RESUMO

Background: Research has shown that potential perpetrators and individuals high in psychopathic traits tend to body language cues to target a potential new victim. However, whether targeting occurs also by tending to vocal cues has not been examined. Thus, the role of voice in interpersonal violence merits investigation.Objective: In two studies, we examined whether perpetrators could differentiate female speakers with and without sexual and physical assault histories (presented as rating the degree of 'vulnerability' to victimization).Methods: Two samples of male listeners (sample one N = 105, sample two, N = 109) participated. Each sample rated 18 voices (9 survivors and 9 controls). Listener sample one heard spontaneous speech, and listener sample two heard the second sentence of a standardized passage. Listeners' self-reported psychopathic traits and history of previous perpetration were measured.Results: Across both samples, history of perpetration (but not psychopathy) predicted accuracy in distinguishing survivors of assault.Conclusions: These findings highlight the potential role of voice in prevention and intervention. Gaining a further understanding of what voice cues are associated with accuracy in discerning survivors can also help us understand whether or not specialized voice training could have a role in self-defense practices.


We examined whether listeners with history of perpetration could differentiate female speakers with and without assault histories (presented as rating the degree of 'vulnerability' to victimization).Listeners' higher history of perpetration was associated with higher accuracy in differentiating survivors of assault from non-survivors.These findings highlight that voice could have a crucial role in prevention and intervention.

RESUMO

Introdução: A voz é um indicador de estados emocionais, influenciada por fatores como o tônus vagal, a respiração e a variabilidade da frequência cardíaca. O estudo explora esses fatores e a relação com a regulação emocional e a prática meditativa como técnica de autorregulação. Objetivo: Investigar a diferença nas características vocais e na variação da frequência cardíaca em meditadores experientes (EM) e novatos (NM) antes e depois de uma prática meditativa e em não praticantes de meditação ­ grupo controle (CG), antes e depois de um teste controle. Métodos: Estudo quase-fatorial 3 x 2. Três grupos foram avaliados (meditadores experientes EM; meditadores novatos NM; e grupo controle CG, não praticantes de meditação) em dois momentos da manipulação experimental ­ antes e depois de uma sessão meditativa para praticantes de meditação, e antes e depois de uma tarefa de busca de palavras para o grupo controle. A frequência fundamental, jitter, shimmer, relação harmônico-ruído e o primeiro (F1), o segundo (F2) e terceiro (F3) formantes da vogal [a]; a variação da frequência cardíaca (SDNN, RMSSD, LF/HF, SD1 and SD2); estado de ansiedade e autopercepção vocal, foram investigados, antes e após a intervenção. Resultados: O grupo EM alcançou ótimo relaxamento do trato vocal. Os grupos NM e CG apresentaram mudanças em F1. Prática meditativa, de longa duração, está associado com grande diferença em F3, SDNN e SD2 na variação da frequência cardíaca. Conclusão: Os resultados sugerem que prática meditativa influencia a expressão vocal e reação emocional, e que a experiência em prática meditativa favorece esta relação. (AU)


Introduction: The voice is an indicator of emotional states, influenced by factors such as vagal tone, breathing and heart rate variability. This study explores these factors and their relationship with emotional regulation and meditative practice as a self-regulation technique. Purpose: To investigate the difference in vocal characteristics and heart rate variability in experienced (EM) and novice (NM) meditators before and after a meditation practice and in non-meditators - control group (CG), before and after a control test. Methods: 3 x 2 quasi-factorial study. Three groups were evaluated (experienced meditators EM; novice meditators NM; and control group CG, non-meditators) at two points in the experimental manipulation - before and after a meditation session for meditators, and before and after a word search task for the control group. The fundamental frequency, jitter, shimmer, harmonic-to-noise ratio and the first (F1), second (F2) and third (F3) formants of the vowel [a]; heart rate variation (SDNN, RMSSD, LF/HF, SD1 and SD2); anxiety state and vocal self-perception, were investigated, before and after the intervention. Results: The EM group achieved optimal vocal tract relaxation. The NM and CG groups showed changes in F1. Long-term meditative practice was associated with a large difference in F3, SDNN and SD2 in heart rate variation. Conclusion: The results suggest that meditation practice influences vocal expression and emotional reaction, and that experience in meditation practice favors this relationship. (AU)

RESUMO

Introduction: The conditions of teachers' work during the COVID-19 pandemic affected teachers' lives regarding voice disorder and stress, even in emergency remote classroom situation. Objective: To analyze the relationship between the presence of voice disorder, job stress, and COVID-19 in teachers when in emergency remote classroom teaching situation at the time of the pandemic. Method: This is a primary, exploratory, observational cross-sectional study with the use of survey forwarded online during the period of emergency classes after the arrival of COVID-19 pandemic in Brazil. The teachers answered the sociodemographic questions about the presence of COVID-19 and the following instruments: Condition of Vocal Production-Teacher [Condição de Produção Vocal - Professor (CPV-P)], Screening Index for Voice Disorder (SIVD), and Job Stress Scale (JSS). Results: Of the 118 teachers analyzed, 94.1% were female; the average age was 44 years. The SIVD recorded the presence of voice disorder in 66.9% of the participants. Regarding the JSS, which are the findings related to stress at work in the demand domain, the teachers showed high levels, a fact which presupposes the existence of pressure of psychological nature to perform their work. Conclusion: The teachers self-reported the presence of voice disorder even in remote class situation, on the occasion of COVID-19, which were more common in older teachers. When comparing the presence of voice disorders, coronavirus symptoms, and stress domains in relation to demand, control, and social support, there was no significance. It is hoped that this study will help to reflect on the need to improve teachers' working conditions, strengthening work-related voice disorder actions and guiding actions for vocal care and well-being.


Introducción: Las condiciones de trabajo de los profesores durante la pandemia de COVID-19 afectaron sus vidas en lo que respecta al trastorno de la voz y el estrés, incluso en situaciones de emergencia en aulas remotas. Objetivo: Analizar la relación entre la presencia de trastorno de la voz, estrés laboral y COVID-19 en profesores cuando se encontraban en situación de emergencia de enseñanza en aulas remotas en la época de la pandemia. Método: Se trata de un estudio primario, exploratorio, observacional de tipo transversal, con el uso de encuesta remitida online durante el periodo de clases de emergencia tras la llegada de la pandemia de COVID-19 en Brasil. Los profesores respondieron a las preguntas sociodemográficas sobre la presencia de COVID-19 y a los siguientes instrumentos: Condición de Producción Vocal-Profesor (CPV-P), Índice de Detección de los Trastornos de la Voz (SIVD) y Escala de Estrés Laboral (JSS). Resultados: De los 118 profesores analizados, el 94,1% eran mujeres; la mediana de edad era de 44 años. El (SIVD) registró la presencia de trastorno de la voz en el 66,9% de los participantes. En cuanto a la JSS, que son los hallazgos relacionados con el estrés laboral en el dominio de la demanda, los profesores mostraron niveles elevados, hecho que presupone la existencia de presiones de naturaleza psicológica para realizar su trabajo. Conclusión: Los profesores autoinformaron de la presencia de trastornos de la voz incluso en situación de clase a distancia, con ocasión del COVID-19, que fueron más frecuentes en los profesores de más edad. Al comparar la presencia de trastornos de la voz, los síntomas del coronavirus y los dominios de estrés en relación con la demanda, el control y el apoyo social, no hubo resultados significativos. Se espera que este estudio ayude a reflexionar sobre la necesidad de mejorar las condiciones de trabajo de los docentes, fortaleciendo las acciones de Trastorno de la voz relacionado con el trabajo (WRVD) y orientando acciones para el cuidado y bienestar vocal.

RESUMO

In recent years, there have been international references to the vocal approach for the specific group of transgender individuals, although the Latin American literature is still very timid on this matter. The purpose of this article is to identify the current norms, statistics, and vocal approach towards transgender individuals in Chile and Argentina, considering the experience of two speech and language pathologists with more than twenty years of experience on voice therapy. Reflections were made on the transgender reality in these countries, the limitations in the implementation of the depathologization of the transgender group were outlined, some current and unreliable statistics were presented, some innovative actions in the public system were highlighted, and the lack of knowledge about the benefits of vocal work for transgender men and women was discussed. The identified aspects could benefit from multicenter research that strengthens speech therapy actions with this group, contributing to depathologization and positive approach.


Desde los últimos años es posible encontrar referencias internacionales sobre el abordaje vocal al grupo específico de las personas transgénero, aunque la literatura latinoamericana sigue muy tímida en este asunto. La propuesta de este artículo es identificar las normas vigentes, estadísticas y abordaje vocal hacia las personas transgénero en Chile y Argentina, considerando la experiencia de dos fonoaudiólogas con más de veinte años de experiencia en terapia vocal. Se hicieron reflexiones sobre la realidad transgénero en los países citados, se delinearon las limitaciones en la puesta en práctica de la despatologización del grupo transgénero, se expusieron algunas estadísticas -vigentes y poco confiables-, se plasmaron algunas acciones novedosas en el sistema público y el desconocimiento sobre los beneficios del trabajo vocal en hombres y mujeres transgénero. Los aspectos detectados podrían beneficiarse de investigaciones multicéntricas que fortalezcan acciones fonoaudiológicas con este grupo, contribuyendo a la despatologización y el abordaje positivo.

RESUMO

Objetivo: Este estudio tuvo como objetivo principal validar el Voice Handicap Index (VHI) y su versión abreviada (VHI-10) adaptados al español rioplatense de Argentina, con objetivos específicos centrados en evaluar su fiabilidad y validez. Metodología: La adaptación cultural incluyó técnicas de traducción directa, síntesis y retrotraducción, evaluación de la equivalencia semántica y aplicación a un grupo piloto. Para la validación se evaluó la fiabilidad de ambos índices adaptados mediante la consistencia interna (coeficiente alfa de Cronbach) y la estabilidad test-retest (prueba de Bland-Altman, CCI y r de Spearman). Además, se examinó la validez de criterio y de constructo. 213 sujetos participaron en la validación del índice adaptado de 30 ítems (123 disfónicos; 90 de control); 113, en la del índice abreviado (63 disfónicos; 50 de control). Resultados: Se constituyó el Índice de Desventaja Vocal (IDV) como la versión adaptada del VHI al español rioplatense de Argentina. Ambos índices demostraron excelente consistencia interna (IDV-30 α = 0,96; IDV-10 α = 0,92) y estabilidad y concordancia (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Se halló alta correlación entre los puntajes de ambos índices y la autoevaluación de la severidad de la disfonía de los participantes (r = 0,85). Ambos índices demostraron capacidad de diferenciar entre individuos con disfonía y sujetos sanos (p< 0,001). El análisis factorial reveló tres factores para el IDV-30 y un factor para el IDV-10. Conclusiones: El IDV-30 e IDV-10 presentan grados adecuados de fiabilidad y validez. Ambos pueden ser incluidos en protocolos de valoración de la función vocal por profesionales de Argentina.


Aim: This study aimed to validate the Voice Handicap Index (VHI) and its abbreviated version (VHI-10) adapted into Rioplatense Spanish from Argentina, with specific goals centered on assessing their reliability and validity. Methods: Cultural adaptation involved direct translation, synthesis and back-translation techniques, followed by an assessment of semantic equivalence and application to a pilot group. For the validation process, the reliability of both adapted indices was assessed through measures of internal consistency (Cronbach's alpha coefficient) and test-retest stability (Bland-Altman test, ICC and Spearman's correlation coefficient). Additionally, we conducted analyses to asses criterion and construct validity. 213 subjects participated in the validation of the adapted 30-items index, (123 with dysphonia; 90 from control group); 113, in the abbreviated version (63 with dysphonia; 50 from control group). Results: The "Índice de Desventaja Vocal" (IDV) was established as the adapted version of the VHI into Rioplatense Spanish from Argentina. Both indeces exhibited excellent internal consistency (IDV-30 α = 0,96; IDV-10 α = 0,92) and satisfactory stability and agreement (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Regarding validity, a strong correlation was observed between the scores of both indeces and the participant's self-assessment of dysphonia degree (r = 0,85). Both indices effectively differentiated between individuals with dysphonia and healthy subjects (p< 0,001). Factor analysis revealed three factors for the IDV-30 and one factor for the IDV-10. Conclusion: The IDV-30 and IDV-10 demonstrate satisfactory levels of reliability and validity. Both indices can be incorporated into the assessment protocols for evaluating the vocal function by professionals in Argentina.

RESUMO

Objective: This study examines factors predicting self-reported voice symptoms in call center workers. Methods: Multivariate analysis and predictive modeling assess personal, work-related, acoustic, and behavioral factors. Generalized Linear Models (GLMs) and Receiver Operating Characteristic (ROC) curves are employed. Results: Age and sleep patterns impacted voice quality and effort, while workplace factors influenced symptom perception. Unhealthy vocal behaviors related to tense voice and increased effort, while hydration was protective. Voice acoustics showed diagnostic potential, supported by ROC data. These findings emphasize voice symptom complexity in call center professionals, necessitating comprehensive assessment. Limitations: This study recognizes its limitations, including a moderate-sized convenience sample and reliance on PROM metrics. Future research should incorporate more objective measures in addition to self-reports and acoustic analysis. Value: This research provides novel insights into the interplay of personal, occupational, and voice-related factors in developing voice symptoms among call center workers. Predictive modeling enhances risk assessment and understanding of individual susceptibility to voice disorders. Conclusion: Results show associations between various factors and self-reported voice symptoms. Protective factors include sleeping more than six hours and consistent hydration, whereas risk factors include working conditions, such as location and behaviors like smoking. Diagnostic models indicate good accuracy for some voice symptom PROMs, emphasizing the need for comprehensive models considering work factors, vocal behaviors, and acoustic parameters to understand voice issues complexity.


Objetivo: Este estudio examina los factores que predicen los síntomas de voz en los trabajadores de call centers. Métodos: Se utilizan análisis multivariados y modelos predictivos para evaluar factores personales, laborales, acústicos y de comportamiento. Se emplean Modelos Lineales Generalizados (GLM) y curvas ROC. Resultados: La edad y los patrones de sueño afectaron la calidad vocal y el esfuerzo, mientras que los factores laborales influyeron en la percepción de síntomas. Los comportamientos vocales no saludables se relacionaron con voz tensa y mayor esfuerzo, mientras que la hidratación fue protectora. Los parámetros acústicos de voz mostraron potencial diagnóstico respaldado por datos de ROC. Los hallazgos subrayan complejidad de síntomas vocales en profesionales de centros de llamadas, requiriendo una evaluación integral. Limitaciones: Este estudio reconoce sus limitaciones, que incluyen una muestra de conveniencia de tamaño moderado y la dependencia de medidas PROMs. Futuras investigaciones deberían incorporar medidas objetivas, además de los autorreportes y análisis acústico. Importancia: Esta investigación aporta nuevos conocimientos sobre factores personales, laborales y síntomas de voz en trabajadores de call centers. El modelado predictivo mejora la evaluación de riesgos y la comprensión de la susceptibilidad individual a trastornos de la voz. Conclusión: Los resultados muestran asociaciones entre diversos factores y los síntomas vocales reportados. Los factores de protección incluyen dormir más de seis horas y una hidratación constante; los factores de riesgo incluyen las condiciones de trabajo, como la ubicación y comportamientos como fumar. Los modelos de diagnóstico indican una buena precisión para algunas PROMs de síntomas de la voz, lo que subraya la necesidad de modelos integrales que tengan en cuenta los factores laborales, los comportamientos vocales y los parámetros acústicos para comprender la complejidad de los problemas de la voz.

RESUMO

Objective: To explore the training and use of auditory perceptual evaluation of the voice reported by Colombian speech-language pathologists. Study Design: Cross-sectional observational research with a quantitative approach. Methods: A digital questionnaire was designed and distributed to gather information regarding professionals' training process and implementation of auditory-perceptual evaluation procedures. Descriptive statistics were applied, and several generalized linear models were adjusted to determine the influence of certain variables on others. Results: The survey received responses from 40 speech-language pathologists, revealing that the most used scales for training and evaluating vocal quality within this group are direct magnitude estimations (82.5% and 77.5%). Similarly, in this group, the tasks most frequently used to train and use as an evaluation strategy are vowel assessments (38%) followed by spontaneous speech (30%). Practitioners of this group were mostly trained using a conceptual framework involving multiple exposures to rating (42.5%). The use of direct magnitude estimation in training with a normal voice showed significance (p = 0.015), as did the use of the vowel /i/ in training with an equal-appearing interval (p = 0.013). The statistical models relating the scale used to the scale on which participants were trained were also significant (p < 0.05). Conclusions: The GRBAS scale is the training tool most used by the group of speech-language pathologists of the study group in Colombia. Future efforts should focus on improving training practices for auditory-perceptual evaluation, exploring alternative conceptual frameworks, and incorporating external references to enhance validity and reliability.


Objetivo: Explorar los reportes de fonoaudiólogos colombianos acerca del entrenamiento y uso de la evaluación perceptual auditiva de la voz. Diseño de estudio: Se eligió un diseño de investigación observacional transversal con un enfoque cuantitativo. Metodología: Se diseñó y distribuyó un cuestionario digital para recopilar información sobre el proceso de formación de los profesionales y la implementación de procedimientos de evaluación perceptual auditiva. Se aplicaron estadísticas descriptivas y se ajustaron varios modelos lineales generalizados para determinar la influencia de ciertas variables en otras. Resultados: La encuesta recibió respuestas de 40 fonoaudiólogos, revelando que las escalas más utilizadas para la formación y la evaluación de la calidad vocal en el grupo son las estimaciones de magnitud directa (82.5% y 77.5%). Del mismo modo, en este grupo las tareas más frecuentemente utilizadas para la formación y el uso como estrategia de evaluación son las vocales (38%), seguidas por el habla espontánea (30%). La mayoría de los profesionales del grupo fueron formados utilizando un marco conceptual que involucra múltiples exposiciones a la calificación (42.5%). El uso de la estimación de magnitud directa en la formación con una voz normal mostró significancia (p = 0.015), al igual que el uso de la vocal /i/ en la formación con intervalos de igual apariencia (p = 0.013). Los modelos estadísticos que relacionan la escala utilizada con la escala en la que los participantes fueron entrenados también fueron significativos (p < 0.05). Conclusiones: La escala GRBAS es la herramienta de formación más utilizada por el grupo de fonoaudiólogos del estudio. Los esfuerzos futuros deberían centrarse en mejorar las prácticas de formación para la evaluación perceptual auditiva, explorar marcos conceptuales alternativos e incorporar referencias externas para mejorar la validez y la confiabilidad.

RESUMO

Purpose: To describe the acoustic characteristics of a classroom, voice quality, fatigue, and vocal load of university professors. Methods: Exploratory, observational, longitudinal, and descriptive study with a single group of participants, including vocal monitoring data over two weeks. Acoustic characterization of the classroom, perceptual-auditory evaluation, and acoustic analysis of voice samples were conducted before and after classes. Vocal dosimetry was performed during classes, and the Vocal Fatigue Index (VFI) was assessed at the beginning of each week. Descriptive analysis of the findings was conducted, and randomization test was performed to verify the internal reliability of the judge. Results: All participants reported speaking loudly in the classroom, with the majority reporting vocal changes in the past six months, and only one participant reported a current vocal change. The classroom had acoustical measures and estimations that deviated from established standards. The professors used high vocal intensities during classes. After the classes, an increase in the absolute values of the aggregated data for CAPE-V, jitter, and fundamental frequency was found, varying within the range of normality. Furthermore, there was an observed increase in both post-lesson intensity and VFI when comparing the two-week period. Conclusions: Vocal intensities and VFI were possibly impacted by the acoustics of the classroom. The increase in average VFI between the weeks may be attributed to a cumulative fatigue sensation. Further research with a larger number of participants and in acoustically conditioned classrooms is suggested in order to evaluate collective intervention proposals aimed at reducing the vocal load on teachers.


Objetivo: Describir las características acústicas, calidad vocal, fatiga y carga vocal de profesores universitarios. Métodos: Estudio exploratorio, observacional, longitudinal, descriptivo con un solo grupo de participantes y datos de monitoreo vocal durante dos semanas. Se realizó caracterización acústica de la sala, evaluación auditiva-perceptiva y acústica de muestras de voz antes y después de las clases. Se realizó dosimetría vocal durante las clases y se verificó el Índice de Fatiga Vocal (IFV) en dos semanas. Se realizó un análisis descriptivo de los hallazgos y una prueba de aleatorización para verificar la confiabilidad interna del juez. Resultados: Todos los participantes informaron hablar en voz alta en clase, la mayoría informó cambios vocales en los últimos seis meses y solo uno informó cambios vocales actuales. La sala presentó mediciones y estimaciones acústicas fuera de las normas establecidas. Los profesores utilizaron intensidades vocales altas durante las clases. Hubo un aumento en los valores absolutos de los datos agrupados para CAPE-V, jitter y frecuencia fundamental, variando dentro de los límites normales, después de las clases. La intensidad después de las clases y el IFV, en la comparación entre las dos semanas, mostraron un aumento. Conclusiones: La dosis vocal y el IFV posiblemente se vieron afectados por la acústica del aula. El aumento del IFV medio entre semanas pudo deberse a la sensación de cansancio acumulada. Se sugieren nuevas investigaciones con un mayor número de participantes y que se realicen en la sala acondicionada acústicamente para evaluar propuestas de intervención colectiva, con el objetivo de reducir la carga vocal de los docentes.

RESUMO

Objectives: To present a simple form of vocal and breathing conditioning for voice professionals based on concepts from vocal science. The vocal conditioning program called Voice Athletes Conditioning uses the principles of exercise physiology to gradually improve vocal and respiratory overload to achieve endurance, power, and flexibility. Methods: Due to our personal experience with high voice users, we synthesized a vocal conditioning program (AVCP) that combines voice science, exercise physiology, sports science and physical therapy principles. This is an 8-week program of daily vocal and breathing exercises with overload enhancement each week using different types of breathing devices and semi-occluded vocal tract exercises, designed and developed according to the specific requirements and performance of the voice professional. Reflections: Professional voice users often experience episodes of vocal fatigue that can directly affect their performance and vocal health. As with physical training for athletes, voice exercises can also contribute to improving vocal conditioning, preventing voice disorders, as well as helping to obtain better performance, greater tolerance to fatigue and shorter recovery time. Conclusions: AVCP is an approach that considers the principles of muscle training aimed objectively at the respiratory and vocal muscles, carried out with a variety of breathing devices and specific vocal exercises in search of greater performance time, less physiological stress, and shorter recovery time in the professional use of the voice.


Objetivos: Presentar una forma sencilla de acondicionamiento vocal y respiratorio para profesionales de la voz, basada en conceptos de la ciencia vocal. El programa de acondicionamiento vocal denominado Voice Athletes Conditioning utiliza los principios de la fisiología del ejercicio para mejorar gradualmente la sobrecarga vocal y respiratoria, con el fin de lograr resistencia, potencia y flexibilidad. Métodos: Debido a nuestra experiencia personal con usuarios de voz aguda, sintetizamos un programa de acondicionamiento vocal (AVCP) que combina principios de la ciencia de la voz, la fisiología del ejercicio, las ciencias del deporte y la fisioterapia. Se trata de un programa de 8 semanas de ejercicios vocales y respiratorios diarios con realce de sobrecarga cada semana utilizando diferentes tipos de dispositivos respiratorios y ejercicios semioclusivos del tracto vocal, diseñado y desarrollado de acuerdo con los requerimientos específicos y el rendimiento del profesional de la voz. Reflexiones: Los usuarios profesionales de la voz experimentan a menudo episodios de fatiga vocal que pueden afectar directamente su rendimiento y salud vocal. Al igual que ocurre con el entrenamiento físico de los deportistas, los ejercicios vocales también pueden contribuir a mejorar el acondicionamiento vocal, prevenir trastornos de la voz, además de ayudar a obtener un mejor rendimiento, una mayor tolerancia a la fatiga y un menor tiempo de recuperación. Conclusiones: El AVCP es un enfoque que considera los principios del entrenamiento muscular dirigido objetivamente a la musculatura respiratoria y vocal, realizado con diversos aparatos respiratorios y ejercicios vocales específicos en busca de un mayor tiempo de actuación, menor estrés fisiológico y menor tiempo de recuperación en el uso profesional de la voz.

RESUMO

Proper timing of flowering under different environmental conditions is critical for plant propagation. Light quality is a pivotal environmental cue that plays a critical role in flowering regulation. Plants tend to flower late under light with a high red (R)/far-red (FR) light ratio but early under light with a low R/FR light ratio. However, how plants fine-tune flowering in response to changes in light quality is not well understood. Here, we demonstrate that F-box of Flowering 2 (FOF2), an autonomous pathway-related regulator, physically interacts with VASCULAR PLANT ONE-ZINC FINGER 1 and 2 (VOZ1 and VOZ2), which are direct downstream factors of the R/FR light receptor phytochrome B (PHYB). We show that PHYB physically interacts with FOF2, mediates stabilization of the FOF2 protein under FR light and end-of-day FR light, and enhances FOF2 binding to VOZ2, which leads to degradation of VOZ2 by SCFFOF2 E3 ligase. By contrast, PHYB mediates degradation of FOF2 protein under R light and end-of-day R light. Genetic interaction studies demonstrated that FOF2 functions downstream of PHYB to promote FLC expression and inhibit flowering under both high R/FR light and simulated shade conditions, processes that are partially dependent on VOZ proteins. Taken together, our findings suggest a novel mechanism whereby plants fine-tune flowering time through a PHYB-FOF2-VOZ2 module that modulates FLC expression in response to changes in light quality.

RESUMO

Introducción: las medidas auditivo-perceptuales subjetivas GRABS (Grade [grado de gravedad], Roughness [aspereza], Asthenia [astenia], Breathiness [soplosidad] y Strain [tensión] y CAPE-V (Consensus Auditory-Perceptual Evaluation of Voice) han sido el estándar de oro en evaluar la voz. La prominencia del pico cepstral suavizado (CPPS) se impone como la medida acústica objetiva más robusta para evaluar la gravedad de la disfonía. Se evaluó el análisis cepstral del programa PRAAT en pacientes con voz patológica y no patológica en hablantes de español colombiano y los valores estándar para el CPPS en lenguaje conectado (CPPSc), comparado con el análisis perceptual de la voz (GRBAS). Métodos: estudio observacional y analítico de prueba diagnóstica, de corte transversal y multicéntrico, con 120 individuos. Se grabó la voz y se analizó el CPPSc con el programa PRAAT. Se aplicó la valoración auditiva-perceptual por dos evaluadores expertos para la escala GRBAS. Resultados: el promedio de edad fue 43,3 años, 64,2 % mujeres. La media del CPPSc en el grupo disfónico fue de 6,40 dB y en el grupo de normofónicos fue 8,54 dB con p=0,000. Sensibilidad de 83,6% y especificidad de 96,2 % para la voz patológica en los pacientes con valores de CPPSc menores a 7,38 dB. Hubo alta correlación del valor de CPPSc con la gravedad de la disfonía. Conclusiones: el valor del CPPSc mediante el programa PRAAT es una medida eficiente por su alta validez, bajo costo y fácil aplicación para evaluar objetivamente la disfonía y su gravedad.


Introduction: Subjective auditory-perceptual measurements, GRABS (Grade, Roughness, Asthenia, Breathiness y Strain) and CAPE-V (Consensus Auditory Perceptual Evaluation of Voice) have been the gold standard in voice evaluation. Recently, the smoothed cepstral peak prominence (CPPS) has been imposed as the acoustic measurement, objective and more robust for dysphonia severity. Objectives: The cepstral analysis of the PRAAT program was evaluated in patients with a patho-logical and non-pathological voice in Colombian Spanish speakers and the standard values for the CPPS in connected language (CPPSc), compared with the perceptual analysis of the voice (GRBAS). Methods: An observational, analytical, cross-sec-tional, multicenter diagnostic test was performed with 120 individuals. The voice was recorded and the CPPSc was analyzed with the PRAAT program. The auditory-perceptual assessment was applied by two expert evaluators for the GRBAS scale. Results: The average age was 43.3 ± 18.1 years, 64.2% were women. The mean CPPSc in the dysphonic group was 6.40 dB, while in the group of normophonic indi-viduals it was 8.54 dB, with significant differences between both groups (p=0.000). Sensitivity of 83.6% and specificity of 96.2%; for pathological voice was established in patients with CPPSc values less than 7.38 dB. A high correlation was found in the CPPSc value with the severity of dysphonia. Conclusions: The value of CPPSc through the Praat program is an efficient measure, due to its high validity, low cost and easy application to objectively evaluate dysphonia and its severity.

RESUMO

La traqueostomía es un procedimiento quirúrgico enfocado en brindar una vía de respiración alterna, en el que sus mayores consecuencias son las afectaciones comunicativas y deglutorias. La evaluación e intervención fonoaudiológica es indispensable dentro del proceso de rehabilitación de pacientes traqueostomizados, teniendo en cuenta las secuelas comunicativas, deglutorias y de fonación asociadas a este procedimiento. El presente artículo tiene como objetivo destacar el rol y actuar fonoaudiológico dentro de la restauración de las funciones alteradas en el caso de una paciente femenina con traqueostomía, quien acude al servicio de urgencias de un hospital público de Bogotá, Colombia. Se aplicaron pruebas estandarizadas y subjetivas para la valoración fonoaudiológica, estableciendo así el plan de manejo enfocado en la restauración de la deglución y la fonación, así como la intervención para el mantenimiento del estado orofacial, sensibilidad y movilidad de las estructuras. Se evidenciaron mejoras en la efectividad y seguridad deglutoria, una exitosa adaptación de válvula fonatoria y mantenimiento de habilidades de lenguaje y cognición, preservando el estado comunicativo. En conclusión, este estudio de caso brinda un aporte significativo con respecto a la importancia del actuar fonoaudiológico, la aplicación de conocimientos y estrategias basadas en la literatura y el análisis, evaluación e intervención.


Tracheostomy is a surgical procedure focused on providing an alternate breathing path, in which its greatest consequences are communication and swallowing impairments.Speech therapy evaluation and intervention is essential within the rehabilitation process of tracheostomized patients, taking into account the swallowing and phonatory consequences associated. The aim of this article is to highlight the role and actions of the speech language therapist in the restoration of altered functions in the case of a female patient with atracheostomy, who went to the emergency department of a public hospital in Bogotá,Colombia, due to swallowing disorders. Standardized and subjective tests were applied for speech therapy assessment. The management plan was developed focused on the restoration of swallowing and phonatory function as well as the intervention to maintain the orofacial state, sensitivity and mobility of the structures. Improvements were evident in swallowing effectiveness and safety, a successful adaptation of the speaking valve and maintenance of language and cognition skills, preserving the communicative state. In conclusion, this case study provides a significant contribution regarding regarding the importance of the speech therapist role, the application of knowledge and strategies based on literature and analysis, evaluation and intervention.

RESUMO

RESUMO Objetivo Investigar a associação entre medidas de desvantagem vocal, sintomas de transtornos mentais comuns e a restrição das atividades de canto ocorrida durante a pandemia de Covid-19 em coralistas amadores. Métodos Estudo descritivo, analítico, transversal, de natureza quantitativa. Para coleta de dados, foram utilizados um questionário de caracterização inicial, o protocolo de Índice de Desvantagem para o Canto Moderno (IDCM) e o SRQ-20, adaptação do Self Reporting Questionnaire, todos eles disponibilizados de forma on-line. A amostra da pesquisa foi constituída por 46 participantes pertencentes aos corais amadores de duas instituições de ensino superior. Resultados As médias do escore total do IDCM e SRQ-20 foram elevadas e estiveram correlacionadas positivamente entre si. Não houve diferença entre as pontuações do IDCM e SRQ-20 para os indivíduos que referiram a infecção por Covid-19, ou não. Indivíduos que afirmaram em suas respostas que sofreram influência da restrição social causada pela pandemia apresentaram escores mais altos do que aqueles que não fizeram essa afirmação. Não houve correlação com o tempo de canto e a desvantagem vocal e a presença de sintomas de transtornos mentais, mensuradas pelo IDCM e SRQ-20, respectivamente. Coralistas que mantiveram suas atividades de canto individual ou coletivamente apresentaram menores prejuízos vocais e emocionais. Conclusão coralistas amadores relataram desvantagem vocal e transtornos mentais comuns possivelmente relacionados às restrições sociais provocadas pela pandemia de Covid-19. Os índices observados, todavia, parecem não estar associados à infecção pelo vírus em si, mas às limitações impostas pela restrição social do período pandêmico.


ABSTRACT Purpose To investigate the association between measures of voice handicap, symptoms of common mental health disorders and the restriction of singing activities that occurred during the Covid-19 pandemic in amateur choristers. Methods This is a cross-sectional, analytical, descriptive and quantitative study. To collect data were used an initial characterization questionnaire, the Modern Singing Handicap Index (MSHI) protocol and the SRQ-20, an adaptation of the Self Reporting Questionnaire, all of which were made available online. The research sample consisted of 46 participants belonging to amateur choirs from two higher education institutions. Results The mean total score for the MSHI and SRQ-20 were high and were positively correlated with each other. There was no difference between the MSHI and SRQ-20 scores between individuals who self-reported Covid-19 infection or not. Individuals who stated that the answers offered in the survey were influenced by the social restrictions caused by the pandemic had higher scores than those who did not make this statement. There was no correlation with singing time and voice handicap and the presence of symptoms of mental health disorders, measured by the MSHI and SRQ-20, respectively. Choristers who maintained their singing activities individually or collectively showed less vocal and emotional damage. Conclusion Amateur choristers reported voice disadvantage and common mental health disorders possibly related to social restrictions caused by the Covid-19 pandemic. The observed rates, however, do not seem to be associated with the virus infection itself, but with the limitations imposed by social restrictions during the pandemic period.

RESUMO

RESUMO Objetivo Descrever o conhecimento de cantores amadores que se apresentam em cultos religiosos sobre saúde e higiene vocal e comparar esses achados em dois momentos distintos. Métodos Pesquisa descritiva, longitudinal, com 100 participantes que praticavam canto amador em cultos religiosos; idades entre 18 e 82 anos (média 33,72 anos), 54 mulheres e 46 homens. Os participantes responderam ao Questionário Inicial, que inclui dados pessoais e autoavaliação vocal, e ao Questionário de Saúde e Higiene Vocal, este em dois momentos, com intervalo de 20 dias e com as questões aleatorizadas. Foi dada devolutiva desse questionário após cada aplicação, por meio da apresentação das respostas corretas de cada um de seus itens. Os dados foram analisados de forma descritiva e inferencial. Resultados A maior parte dos cantores referiu algum grau de alteração vocal e relatou ao menos um sintoma vocal (principalmente pigarro e falha na voz). A pontuação foi maior na segunda aplicação do questionário e não houve correlação entre a autoavaliação vocal e a pontuação obtida. Conclusão Cantores amadores de ambos os gêneros que se apresentam em cultos religiosos demonstraram conhecimento sobre saúde e higiene vocal correspondente ao de indivíduos vocalmente saudáveis, acima do ponto de corte em ambas as aplicações do Questionário de Saúde e Higiene Vocal. Contudo, a maioria referiu alterações e sintomas vocais. Verificou-se aumento do conhecimento sobre saúde e higiene vocal na segunda aplicação, ainda que discreto. O nível de conhecimento sobre saúde e higiene vocal não se correlacionou com o grau de alteração vocal.


ABSTRACT Purpose To describe the knowledge of amateur singers who perform in religious services, about vocal health and hygiene, and compare these findings at two different moments. Methods Descriptive, longitudinal research with 100 participants who practice amateur singing in religious services; ages between 18 and 82 years (average 33.72 years), 54 women and 46 men. Participants answered the Initial Questionnaire (Q1), which includes personal data and vocal self-assessment, and the Vocal Health and Hygiene Questionnaire (QSHV), on two occasions with an interval of 20 days and with the questions randomized. The participants were given a feed-back of the QSHV after each application i.e. the correct answers to each item. The data were analyzed descriptively and inferentially. Results Most singers reported some degree of self-assessed vocal alteration and reported at least one vocal symptom (mainly throat clearing and voice failure). The score was higher in the second application of the QSHV and there was no correlation between the vocal self-assessment and the score obtained in the QSHV. Conclusion Amateur singers of both sexes who perform in religious services demonstrated knowledge about vocal health and hygiene corresponding to that of vocally healthy individuals, above the cutoff point in both applications; however, the majority reported vocal changes and symptoms. There was an increase in knowledge about vocal health and hygiene in the second application, however discreet. The level of knowledge about vocal health and hygiene did not correlate with the degree of vocal alteration.

RESUMO

RESUMO Objetivo avaliar a capacidade de estudantes de medicina para reconhecer emoções pela voz e expressão facial, por meio de avaliações de percepção emocional da entonação vocal e das expressões faciais. Métodos estudo com delineamento transversal observacional. Para avaliação do reconhecimento de emoções pelas expressões faciais, utilizou-se um teste composto por 20 vídeos de microexpressões faciais e, para avaliação do reconhecimento emocional pela voz, utilizou-se o Protocolo de Reconhecimento de Emoções Prosódicas Básicas, baseado no banco de dados de Burkhardt. Para análise estatística, foram utilizados os testes de Friedman, Shapiro-Wilk, teste t de Student ou Mann-Whitney e o coeficiente de correlação de Pearson ou Spearman. Resultados o estudo foi composto por 38 alunos, com média de idade de 20,8 (±2,5). O reconhecimento de emoções pela voz foi significativamente superior, comparado com os resultados do teste de reconhecimento de emoções pelas expressões faciais. Houve correlação positiva entre a idade e a habilidade de reconhecer emoções pelas expressões faciais. O gênero masculino apresentou taxa significativa de acertos, superior ao gênero feminino na habilidade de reconhecer emoções pela expressão facial. As emoções com maior média de acertos pela expressão facial foram surpresa, alegria e desprezo, enquanto, por meio da voz, as emoções foram raiva, medo e tristeza. Conclusão a capacidade de reconhecimento de emoções por estudantes de medicina foi maior na avaliação de percepção emocional por meio da voz.


ABSTRACT Purpose To evaluate the ability of medical students to recognize emotions through voice and facial expression through assessments of emotional perception of vocal intonation and functional expressions. Methods Observational cross-sectional study. To evaluate the recognition of emotions by facial expressions, a test composed of 20 videos of facial microexpressions was used, and to evaluate the emotional recognition by voice, the protocol of prosodic impressions of basic emotions, based on the Burkhardt database, was used. For statistical analysis, the Friedman, Shapiro-Wilk, Student t, Mann-Whitney and Pearson or Spearman correlation coefficient tests were used. Results The study consisted of 38 students, with an average age of 20.8 (±2.5). The recognition of emotions through the voice was significantly superior to the one through facial expressions. There was a positive correlation between age and the ability to recognize emotions through facial expressions. Males had a significantly higher hit rate than females in the ability to recognize emotions through facial expression. The emotions with the highest average success rates through facial expression were surprise, joy and contempt, while, through the voice, the emotions were anger, fear and sadness. Conclusion The ability to recognize emotions by medical students was greater when assessing emotional perception through the voice.

RESUMO

RESUMO Objetivo Traduzir e adaptar de forma transcultural o Iranian Voice Quality of Life Profile (IVQLP) para o português brasileiro (PB). Método O processo de adaptação transcultural foi realizado por meio de cinco etapas: tradução do IVQLP para o PB por três especialistas nativos do PB e fluentes no inglês americano; elaboração de uma versão de consenso; retrotradução por um especialista nativo do inglês americano e fluente no PB; análise por um comitê de cinco especialistas e elaboração da versão final do instrumento em PB, denominado IVQLP-Br; e pré-teste. O IVQLP-Br tem o objetivo de avaliar os impactos da voz de uma forma mais abrangente, englobando vários domínios da vida dos indivíduos, apresenta 43 itens e uma chave de respostas de cinco pontos. Para o pré-teste foi acrescida como opção para o respondente a alternativa "não aplicável". Participaram do pré-teste 36 indivíduos adultos com risco autorrelatado para disfonia. Resultados Na etapa de tradução 10 itens foram modificados e na retrotradução, 15 itens necessitaram de ajustes. Nenhum item precisou ser reformulado após a aplicação na população-alvo, pois a opção "não aplicável" apareceu em doze respostas, porém, sem significância estatística. Conclusão Conclui-se que a versão traduzida do IVQLP para o PB, denominado IVQLP-Br, apresentou equivalência transcultural e pode ser utilizada para uma análise mais detalhada do impacto da voz nos diferentes domínios da vida dos indivíduos. Após a validação, o IVQLP-Br poderá contribuir tanto para a prática clínica, quanto para pesquisas com falantes do PB.


ABSTRACT Purpose To cross-culturally adapt the Voice Quality of Life Profile (IVQLP) into Brazilian Portuguese (BP). Methods The cross-cultural adaptation process was performed in five stages: translation of the IVQLP into BP by three native BP experts fluent in American English; preparation of a consensus version; back-translation by a native American English expert fluent in BP; analysis by a committee of five experts and preparation of the final version of the instrument in BP, which was named IVQLP-Br; and pre-testing. The IVQLP-Br aims to assess the impacts of the voice more comprehensively, encompassing various areas of an individual's life. It has 43 items and a five-level response key. For the pre-test, the alternative "not applicable" was added as a response option. Thirty-six adults with self-reported risk of dysphonia participated in the pre-test. Results In the translation stage, ten items were modified, and during the back-translation, 15 items required adjustments. No questions required reformulation after the application of the IVQLP-Br in the target population, because the option "not applicable" appeared in 12 responses without statistical significance. Conclusion The version of the IVQLP translated into BP, named the IVQLP-Br, exhibited cross-cultural equivalence and was administrable for a more detailed analysis of the impact of the voice in different domains of an individual's life. After validation, the IVQLP-Br will be able to contribute both to clinical practice and to research with BP speakers.

RESUMO

RESUMO Objetivo Avaliar o efeito imediato do exercício inspiratório com incentivador e exercitador respiratório na voz de mulheres sem queixas vocais. Método Participaram 25 mulheres sem queixas vocais, entre 18 e 34 anos, com pontuação 1 no Índice de Triagem para Distúrbio Vocal (ITDV). A coleta de dados foi realizada nos momentos antes e após realização de exercício inspiratório e consistiu na gravação de vogal sustentada /a/, fala encadeada e tempos máximos fonatórios (TMF) de vogais, fonemas fricativos e contagem de números. No julgamento perceptivo-auditivo foi utilizada a Escala de Desvio Vocal (EDV) para verificar o grau geral do desvio vocal. Avaliação acústica foi feita no software PRAAT e foram extraídos os parâmetros frequência fundamental (f0), jitter, shimmer, proporção harmônico -ruído (HNR), Cepstral Peak Prominence Smoothed (CPPS), Acoustic Voice Quality Index (AVQI) e Acoustic Breathiness Index (ABI). Para mensuração das medidas aerodinâmicas, o tempo de emissão foi extraído no programa Audacity. Para comparar os resultados utilizou-se o teste paramétrico t de Student para amostras dependentes na análise das variáveis com distribuição normal e o teste de Wilcoxon para variáveis com distribuição não normal. Resultados Não houve diferenças entre os resultados do JPA e das medidas acústicas, nos momentos pré e pós exercício inspiratório. Quanto às medidas aerodinâmicas foi possível observar aumento significativo no valor do TMF /s/ (p=0,008). Conclusão Não houve modificação na qualidade vocal após o exercício inspiratório com incentivador e exercitador respiratório, porém foi observado aumento do TMF do fonema /s/ após a realização do exercício.


ABSTRACT Purpose To evaluate the immediate effect of the inspiratory exercise with a booster and a respiratory exerciser on the voice of women without vocal complaints. Methods 25 women with no vocal complaints, between 18 and 34 years old, with a score of 1 on the Vocal Disorder Screening Index (ITDV) participated. Data collection was performed before and after performing the inspiratory exercise and consisted of recording the sustained vowel /a/, connected speech and maximum phonatory times (MPT) of vowels, fricative phonemes and counting numbers. In the auditory-perceptual judgment, the Vocal Deviation Scale (VSD) was used to verify the general degree of vocal deviation. Acoustic evaluation was performed using the PRAAT software and the parameters fundamental frequency (f0), jitter, shimmer, harmonium-to-noise ratio (HNR), Cepstral Peak Prominence Smoothed (CPPS), Acoustic Voice Quality Index (AVQI) and Acoustic Breathiness Index (ABI). To measure the aerodynamic measurements, the time of each emission was extracted in the Audacity program. Data were statistically analyzed using the Statistica for Windows software and normality was tested using the Shapiro-Wilk test. To compare the results, Student's and Wilcoxon's t tests were applied, adopting a significance level of 5%. Results There were no significant differences between the results of the JPA and the acoustic measures, in the pre and post inspiratory exercise moments. As for the aerodynamic measures, it was possible to observe a significant increase in the value of the TMF /s/ (p=0.008). Conclusion There was no change in vocal quality after the inspiratory exercise with stimulator and respiratory exerciser, but an increase in the MPT of the phoneme /s/ was observed after the exercise.

RESUMO

RESUMO Objetivo Comparar as medidas acústicas de Cepstral Peak Prominence Smoothed (CPPS) e Acoustic Voice Quality Index (AVQI) de crianças com vozes normais e alteradas, relacionar com o julgamento perceptivo-auditivo (JPA) da voz e estabelecer pontos de corte. Método Gravações vocais das tarefas de vogal sustentada e contagem de números de 185 crianças foram selecionadas em um banco de dados e submetidas a análise acústica com extração das medidas de CPPS e AVQI, e ao JPA. O JPA foi realizado individualmente para cada tarefa e as amostras foram classificadas posteriormente como normal ou alterada, e para as tarefas em conjunto definindo-se se a criança passaria ou falharia em uma situação de triagem vocal. Resultados Crianças com JPA alterado e que falharam na triagem apresentaram valores menores de CPPS e maiores de AVQI, do que as com JPA normal e que passaram na triagem. O JPA da tarefa de vogal sustentada se relacionou ao CPPS e AVQI, e da tarefa de contagem de números relacionou-se apenas ao AVQI e CPPS números. Os pontos de corte que diferenciam crianças com e sem desvio vocal são 14,07 para o CPPS vogal, 7,62 para o CPPS números e 2,01 para o AVQI. Conclusão Crianças com JPA alterado apresentaram maiores valores de AVQI e menores valores de CPPs. O JPA da tarefa de vogal previu todas as medidas acústicas, porém, de contagem previu apenas as medidas extraídas dela. As três medidas foram semelhantes na identificação de vozes sem desvio e vozes disfônicas.


ABSTRACT Purpose To compare the acoustic measurements of Cepstral Peak Prominence Smoothed (CPPS) and Acoustic Voice Quality Index (AVQI) of children with normal and altered voices, to relationship with auditory-perceptual judgment (APJ) and to establish cut-off points. Methods Vocal recordings of the sustained vowel and number counting tasks of 185 children were selected from a database and submitted to acoustic analysis with extraction of CPPS and AVQI measurements, and to APJ. The APJ was performed individually for each task, classified as normal or altered, and for the tasks together defining whether the child would pass or fail in a situation of vocal screening. Results Children with altered APJ and who failed the screening had lower CPPS values and higher AVQI values, than those with normal APJ and who passed the screening. The APJ of the sustained vowel task was related to CPPS and AVQI, and APJ of the number counting task was related only to AVQI and CPPS numbers. The cut-off points that differentiate children with and without vocal deviation are 14.07 for the vowel CPPS, 7.62 for the CPPS numbers and 2.01 for the AVQI. Conclusion Children with altered voices, have higher AVQI values and lower CPPS values, when detected in children with voices within the normal range. The acoustic measurements were related to the auditory perceptual judgment of vocal quality in the sustained vowel task, however, the number counting task was related only to the AVQI and CPPS. The cut-off points that differentiate children with and without vocal deviation are 14.07 for the CPPS vowel, 7.62 for the CPPS numbers and 2.01 for the AVQI. The three measures were similar in identifying voices without deviation and dysphonic voices.
