RESUMO

Despite the lack of findings in laryngeal endoscopy, it is common for patients to undergo vocal problems after thyroid surgery. This study aimed to predict the recovery of the patient's voice after 3 months from preoperative and postoperative voice spectrograms. We retrospectively collected voice and the GRBAS score from 114 patients undergoing surgery with thyroid cancer. The data for each patient were taken from three points in time: preoperative, and 2 weeks and 3 months postoperative. Using the pretrained model to predict GRBAS as the backbone, the preoperative and 2-weeks-postoperative voice spectrogram were trained for the EfficientNet architecture deep-learning model with long short-term memory (LSTM) to predict the voice at 3 months postoperation. The correlation analysis of the predicted results for the grade, breathiness, and asthenia scores were 0.741, 0.766, and 0.433, respectively. Based on the scaled prediction results, the area under the receiver operating characteristic curve for the binarized grade, breathiness, and asthenia were 0.894, 0.918, and 0.735, respectively. In the follow-up test results for 12 patients after 6 months, the average of the AUC values for the five scores was 0.822. This study showed the feasibility of predicting vocal recovery after 3 months using the spectrogram. We expect this model could be used to relieve patients' psychological anxiety and encourage them to actively participate in speech rehabilitation.

RESUMO

With the acceleration of the modernization of human society, natural ecology is continuously destroyed, which inevitably brings about the crisis of the human spirit, and human beings progressively lose the ability to draw power from nature. Similarly, music is losing its function of freeing people from secularity and becoming a carrier of pure utility. For a long time, there have been some disharmonious factors in the ecological environment of vocal music teaching. For example, some vocal music teaching facilities are out of date, vocal music course resources are single and scarce, vocal music courses are comparatively isolated and lack organic integration with other courses, and relevant art practices and scientific research activities of teachers and students are not carried out well after class, comprehensive quality of teachers cannot be effectively improved, and external communication of colleges and universities is not enough. This has affected the quality of vocal music teaching to a certain extent. Accordingly, an environment-friendly ecological vocal education emerged. In addition, both building and music are the supplement and creation of the human living environment by the material organization. Consequently, their performance has similar characteristics of origin. Thus, from the perspective of the building, we touch the music, listen to the building, and analyze the integration of ecological vocal music education and building. The empirical test verified the effect of ecological vocal music teaching under the building vision.

RESUMO

During the COVID-19 pandemic, a number of infection clusters associated with choral singing have been reported. Singing generates droplets and carries the risk of spreading infection. However, no reports have explored droplet flight and aerosol production rates by singing and speaking in Japanese. First, we conducted an observation experiment evaluating the maximum flight distance and number of droplets generated by singing in Japanese, using a high-speed camera and particle counter. Twenty amateur choir members, 10 male and 10 female (five members for each of the four voices), participated in the experiment. Subsequently, although the maximum distance that droplets traveled by singing in Japanese was 61 cm for men (median of 46.5, interquartile range, 36-57) and 56 cm for women (median of 27.5, interquartile range, 20-50), droplets were observed anteriorly and laterally to be up to 66.8 cm. At the singer's mouth, ≥ 5 µm droplets were observed, whereas not observed at 1 meter toward the front of the singers in women and men, respectively. In German singing, droplets were observed up to 111 cm toward the front of the singer, possibly reflecting differences in pronunciation. In Japanese reading aloud, droplets were also observed up to 47 cm toward the front, whereas no droplet dispersion was observed by speaking the Japanese /a/ vowel or singing with wearing surgical mask toward the front. The aerosols produced when reading singing the /u/ vowels were significantly higher than those in other vowels. When singing in a choral group, keeping a sufficient distance at the front and side is recommended in minimizing infectious spread. If distance is not possible, practicing with /a/ vowels and avoiding consonants may be an alternative method. Our observations lasted only 50 seconds per song, and further observational studies are needed to determine the dynamics of aerosols that stay for long periods.

RESUMO

OBJECTIVE: Voice quality disorders remain a problem with classical surgical method which is expected to decrease with new minimally invasive methods. We aimed to examine whether there is an impairment in voice quality among our patients who have undergone open minimally invasive parathyroid surgery. METHODS: Forty-seven primer hyperparathyroidism patients included in the study. Their video laryngoscopic evaluations and voice analyses were done in pre-operative and post-operative 6th month, and changes in the voice quality were examined. RESULTS: Eighty-five (85.1%) of patients were female, with a mean age of 51.5 ± 9.4. According to the voice analysis in the preoperative-postoperative 6th months, F0 (%): 210.616-211.443, Jitt (%): 0.699-0.735, RAP (%): 0.420-0.444, Shim (%): 2.535-2.736, NHR (dB): 0.119-0.123, and VTI: 0.044-0.045, respectively. No significant differences were observed in any of the acoustic parameters between the pre- and post-operative periods. CONCLUSION: No deterioration in voice quality was observed in patients undergoing novel minimally invasive surgical technique. In this respect we think that this new method will be much more advantageous in terms of preserving the voice quality in eligible patients.


OBJECTIVO: Los trastornos de la calidad de la voz siguen siendo un problema con el método quirúrgico clásico y se espera que disminuyan con los nuevos métodos mínimamente invasivos. Nuestro objetivo fue examinar si existe un deterioro en la calidad de la voz entre nuestros pacientes que se han sometido a una cirugía abierta de paratiroides mínimamente invasiva. MÉTODOS: Se incluyeron en el estudio 47 pacientes con hiperparatiroidismo primario. Sus evaluaciones videolaringoscópicas y análisis de voz se realizaron en el sexto mes preoperatorio y posoperatorio, y se examinaron los cambios en la calidad de la voz. RESULTADOS: Ochenta y cinco (85,1%) de los pacientes eran mujeres, con una edad media de 51,5 ± 9,4. Según el análisis de voz en el sexto mes preoperatorio-posoperatorio, F0 (%): 210.616-211.443, Jitt (%): 0.699-0.735, RAP (%): 0.420-0.444, Shim (%): 2.535-2.736, NHR (dB): 0,119-0,123 y VTI: 0,044-0,045 respectivamente. No se observaron diferencias significativas en ninguno de los parámetros acústicos entre el pre y postoperatorio. CONCLUSIÓN: No se observó deterioro en la calidad de la voz en pacientes sometidos a una técnica quirúrgica mínimamente invasiva novedosa. Teniendo en cuenta que este método brindará la oportunidad de preservar la calidad de la voz en pacientes elegibles.

RESUMO

PURPOSE: Postswallow voice abnormality is often assumed to indicate the presence of material in the laryngeal airway (MIA), but prior research has not shown definitive evidence of a causal relationship. This study investigated if endoscopically confirmed MIA (prandial material or secretions) generates specific voice quality attributes that can be perceptually identified by experienced listeners. METHOD: Forty-four dysphagic adults underwent endoscopic evaluation of swallowing. Time-linked audiovisual recordings of pre- and postswallow phonation were analyzed to determine the presence, amount, and location of prandial material or secretions in the larynx during phonation. Expert listeners completed auditory-perceptual ratings of phonation samples. RESULTS: Voice quality ratings did not differ significantly when there was MIA during postswallow phonation. However, judgments of voice quality abnormality for MIA samples were elevated when analyses controlled for effects of baseline dysphonia. Listeners were most likely to perceive voice quality abnormality when larger amounts of secretions were present, as compared to prandial material. Interrater reliability was variable and ranged from low to moderate across perceptual parameters. CONCLUSIONS: MIA during phonation occurred for many participants, but perception of voice quality abnormality was variable when MIA was present. Baseline dysphonia is common among individuals with dysphagia and may limit perception of voice quality abnormalities generated by MIA. Secretions in the laryngeal airway may have a greater impact on voice quality parameters.

RESUMO

Background and Objectives: The efficiency and optimal voice rest period following phonosurgery remains debatable. Platelet-rich plasma (PRP) is a safe and cheap alternative to many bioactive agents being studied on animal models, and is already in use in many medical areas. We investigate the short-term effects of PRP and voice rest on voice outcomes following phonosurgery as an alternative to voice rest alone. Materials and Methods: A prospective single-blinded pilot study was conducted. Sixteen patients with a diagnosis of vocal fold cyst and polyps were included, forming equal groups (PRP and voice rest vs. voice rest alone). Voice analysis was carried out on the preoperative day, day three, and week three following surgery. The measured parameters were fundamental frequency (F0), noise-signal ratio (NSR), harmonic poverty (HP), attack alteration (AL), pitch instability (PI), and amplitude instability (AI).VHI(Voice Handicap Index)-30 questionnaires were carried out before surgery and three weeks following surgery to assess the impact of subjective voice change on quality of life. PRP was obtained using commercial kits with separator gel. Results: An average 3.68-fold increase in platelets was obtained with PRP. No side effects were noted after injection. All voice parameters improved on day three and week three following surgery. Statistical significance was noted only in the fundamental frequency of male patients (p = 0.048) in favor of the PRP-voice rest group. In addition, the VHI- 30 questionnaire results between preoperative and postoperative assessments showed statistically significant differences in total VHI score (p = 0.02) as well as the physical (p = 0.05) and emotional (p = 0.02) scale in favor of the PRP-voice rest group. Conclusions: PRP presents short term safety in patients who undergo phonosurgery, although long-term outcomes are unknown. PRP and voice rest are superior to voice rest alone when considering subjective assessment of the voice. When analyzing acoustic parameters, PRP and voice rest are not superior to voice rest alone.

RESUMO

Objective: Patients with locally advanced laryngeal and hypopharyngeal cancer (LHC) are often treated with chemo-radiotherapy to avoid total laryngectomy, although voice problems may occur even if not markedly manifest. We sought to evaluate the impact of chemoradiation on voice and quality of life. Methods: We studied 21 patients with locally advanced LHC with tumour control at least two years after chemo-radiotherapy. None manifested clinical symptoms related to the treatment and maintained an activity considered as within normal limits. All patients had a voice handicap index (VHI) of less than 15. Voice function was evaluated by perceptual vocal analysis (CAPE-V) and aerodynamic and acoustic study. Quality of life was assessed with the EORTC-H&N35 (voice items 46, 53 and 54). Results: Voice changes were frequent, with alterations in all CAPE-V attributes, and predominantly type II and III spectrograms in acoustic analysis (78%). The EORTC-H&N35 scale showed a reduction in scores in 10-40% of items related to voice. Conclusions: Subclinical voice disorders are common after chemo-radiotherapy. Although patients consider vocal impairment to be very minor and to not interfere with their daily life, it may contribute to a reduced quality of life.

RESUMO

PURPOSE: To analyze and compare the degree of cervical disability in singers with dysphonia and in singers without self-reported vocal complaints. METHODS: A cross-sectional observational analysis. Sixty-two singers participated in the study: Thirty-two singers without vocal complaints and 30 singers with a speech-language pathology and otorhinolaryngological diagnosis of dysphonia. For singers without vocal complaints, two questionnaires were applied via Google Forms: A three-question questionnaire regarding vocal complaints and how each singer perceived their speaking and singing voice, and the Copenhagen Neck Functional Disability Scale (CNFDS). Data on singers with dysphonia were extracted from a database previously collected by a team of researchers at the speech-language pathology department of the Federal University of Minas Gerais. The difference in data collection methodology between the two groups was due to restrictions presented by the coronavirus pandemic. The Mann-Whitney test was used to compare the two groups, at a significance level of 5%. RESULTS: There was a significant difference between the groups (p=0.0001), demonstrating that singers with dysphonia suffered more from cervical pain and discomfort than singers without vocal complaints. CONCLUSION: Singers with dysphonia have more cervical pain and discomfort than singers without vocal complaints, thus presenting with greater cervical disability.


OBJETIVO: analisar e comparar o grau de incapacidade cervical em cantoras disfônicas e em cantoras sem queixas vocais autorreferidas. MÉTODO: estudo observacional analítico transversal. Participaram do estudo 32 cantoras sem queixas vocais e 30 cantoras com diagnóstico fonoaudiológico e otorrinolaringológico de disfonia. Para as cantoras sem queixas vocais foram utilizados dois questionários aplicados virtualmente via GoogleForms, sendo um questionário composto por três perguntas referentes às queixas vocais e como cada cantora percebia sua voz de falada e de forma cantada e a Escala Funcional de Incapacidade do Pescoço de Copenhagen (EFIPC). Os dados referentes às cantoras disfônicas foram extraídos de um banco de dados previamente coletado por uma equipe de pesquisadores no Observatório de Saúde Funcional em Fonoaudiologia da Universidade Federal de Minas Gerais e a diferença na metodologia de coleta de dados entre os dois grupos deu-se devido às restrições apresentadas pela pandemia causada pelo coronavírus. Para a comparação entre os dois grupos, foi utilizado o teste Mann-Whitney e foi considerado um nível de significância de 5%. RESULTADOS: Houve diferença significativa entre os grupos (p=0,0001), demonstrando que as cantoras disfônicas sofrem mais com dores e desconfortos cervicais do que as cantoras sem queixas vocais. CONCLUSÃO: cantoras disfônicas apresentam mais dor e desconforto cervical do que as cantoras sem queixas vocais, caracterizando uma maior incapacidade cervical.

RESUMO

With the continuous improvement of people's living standards, the requirements of music majors for their training standards are also increasing, which leads to the development of music training in the direction of intelligence. This paper discusses the problems of breathing, coordination, and muscle control ability in vocal training and puts forward a vocal training method based on dynamic adjustment factor and Monte Carlo algorithm to solve the difficult problem of vocal training for college students and understand the relationship between vocal training and exercise. Firstly, the sports training set and vocal pronunciation training set are constructed in the form of clustering, and the samples in the set are analyzed discretely to ensure that the samples conform to normal distribution; then, using the Monte Carlo algorithm analyzes the two sample sets and finds out the relationship between exercise and vocal training. Finally, according to breathing, coordination, muscle control ability, and other indicators, calculate the impact of exercise on vocal sound. MATLAB simulation shows that the method proposed in this paper can analyze the influence of exercise on vocal vocalization from the perspective of breathing, coordination, muscle control ability, and other indicators. The accuracy of judgment results is more than 95%, and the time is less than 1 min. All indicators are better than traditional vocal training methods (90%, 2 min), which shows the effectiveness of the method proposed in this paper.

RESUMO

PURPOSE: Vocal roughness is often present in many voice disorders but the assessment of roughness mainly depends on the subjective auditory-perceptual evaluation and lacks acoustic correlates. This study aimed to apply the concept of roughness in general sound quality perception to vocal roughness assessment and to characterize the relationship between vocal roughness and temporal envelop fluctuation measures obtained from an auditory model. METHOD: Ten /ɑ/ recordings with a wide range of roughness were selected from an existing database. Ten listeners rated the roughness of the recordings in a single-variable matching task. Temporal envelope fluctuations of the recordings were analyzed with an auditory processing model of amplitude modulation that utilizes a modulation filterbank of different modulation frequencies. Pitch strength and the smoothed cepstral peak prominence were also obtained for comparison. RESULTS: Individual simple regression models yielded envelope standard deviation from a modulation filter with a low center frequency (64.3 Hz) as a statistically significant predictor of vocal roughness with a strong coefficient of determination (r 2 = .80). Pitch strength and CPPS were not significant predictors of roughness. CONCLUSION: This result supports the possible utility of envelope fluctuation measures from an auditory model as objective correlates of vocal roughness.

RESUMO

BACKGROUND: Auditory-perceptual evaluation of dysphonic voice is an essential clinical activity that characterizes the nature of dysphonia and aids in planning its clinical management. Although there are multidimensional acoustic measures that correlate well with overall severity ratings, they tend to include measures that have only small or moderate correlations with individual voice characteristics frequently perceptually measured (e.g., breathiness or roughness). Given this difference between perceptual and acoustic measures, it is unclear how much individual voice characteristics contribute to a listener's perception of overall severity of dysphonia. PURPOSE: The purpose of this study was to explore individual voice characteristics' relative contribution to the rating of overall dysphonia severity and to explore sex-related differences. METHOD: Two hundred ninety-six voice samples were accessed from the Perceptual Voice Qualities Database. Roughness, breathiness, asthenia, strain, pitch, and loudness ratings from the Grade, Roughness, Breathiness, Asthenia, Strain and Consensus Auditory-Perceptual Evaluation of Voice scales were used to predict overall voice quality severity in linear regression with bootstrapped coefficients. RESULTS: Roughness, breathiness, and strain were the strongest predictors of overall severity. Asthenia and, to a lesser extent, pitch were also significant predictors of overall severity. Loudness was not a significant predictor. There were several sex-related differences noted, as well as differences related to the scale used. CONCLUSIONS: Breathiness, roughness, and strain were all important predictors of overall severity for all regressions. Clinicians should be aware of scale-related differences if they are using auditory-perceptual measures to choose voice therapy targets. Analyses accounting for perceptual strategy differences were recommended for future studies.

RESUMO

Objective:To analysis speech pathology based on dysphonia in speech and voice(ADSV). Methods:The acoustic signals of continuous vowels and continuous speech of one-hundred and thirteen individuals were collected, including 93 vocal cord polyps cases, 20 glottis laryngeal carcinoma cases and 47 volunteers without speech sound disorders. Cepstral peak prominence(CPP), CPP standard deviation(CPP SD), L/H spectral ratio(L/H ratio), L/H ratio standard deviation(L/H ratio SD) and cepstral/spectral index of dysphonia(CSID) were analyzed by ADSV to explore the role of these parameters in the recognition of speech pathology. Results:In the acoustic signal of continuous vowels, CPP and L/H ratio in normal group were higher than those in pathological voice group(P<0.001), while CPP SD and CSID were lower than those in pathological voice group(P<0.001), CPP and CSID areas under ROC curve were 0.95 and 0.99, respectively, which were important acoustic parameters for diagnosing pathological voice. In continuous speech acoustic signals, CPP, CPP SD and L/H ratio in the normal group were all higher than those in the speech disorders group(P<0.001), and the area under the curve of CPP SD was 0.90, which showed high accuracy in diagnosing pathological voice. The ADSV voice analysis parameters CPP, CPP SD, CSID, and L/H ratio also showed significant differences between the vocal cord polyp group and the glottic laryngeal cancer group. The results of the discriminant analysis model show that the use of ADSV voice parameters can distinguish vocal cord polyps and laryngeal cancers. Conclusion:The ADSV voice analysis parameters can not only distinguish the voice signals of the normal group and the pathological group, but also distinguish different types of pathological voices. It has high sensitivity and specificity in diagnosing pathological voices.

RESUMO

Feminization Laryngoplasty evolved from the aim to change a voice from a male quality to a female quality. Larynx and pharynx in a male have undergone enlargement during puberty and as there is no endocrine method for shrinking structures, a surgery that reduces the size of male structures toward the size of female structures might appropriately alter the voice. A smaller larynx and pharynx might raise both the fundamental frequency of the voice and the resonant frequency of the vocal tract. The surgery is used for transgender individuals who desire a female voice, for individuals who fail speech therapy and for complications of tracheal shave procedures whereby the vocal cords have been loosened.

RESUMO

Vocal dysphoria is present for many transgender individuals. Voice goals are defined by each individual client. Voice modification work can be challenging for both clinicians and clients, involving both direct and indirect aspects of intervention. The latter are likely to be less known to otolaryngologists but can form a significant part of clinical practice for experienced speech pathologists. Varying experience levels of treating clinicians can in turn have a bearing on the vocal outcomes achieved by clients. Those who do seek surgical assistance benefit from appropriate presurgery speech and language therapy evaluation and postsurgical voice rehabilitation and treatment.

RESUMO

BACKGROUND: Vocal cord palsy after cervical mediastinoscopy is usually reported at less than 1%. However, its incidence might be underestimated and no follow-up studies are available. Our study aimed to evaluate the incidence of voice changes after cervical mediastinoscopy and report on long-term outcomes, including quality of life, after at least one-year follow-up. METHODS: A retrospective cohort study was performed, considering all patients who underwent cervical mediastinoscopy in our center between January 2011 and April 2016. Patients with pre-existing voice changes, voice changes only after pulmonary resection and patients who underwent neoadjuvant chemo(radio)therapy were excluded. Voice changes with full recovery within 14 days were attributed to intubation-related causes. Follow-up questionnaires, including the standardized Voice Handicap Index, were sent to patients with documented voice changes. RESULTS: Of 270 patients who were included for final analysis, 17 (6.3%) experienced voice changes after cervical mediastinoscopy, which persisted > 2 years in 4 patients (1.5%), causing mild to moderate disabilities in daily living. Twelve patients (out of 17, 71%) were referred for otolaryngology consultation, and paresis of the left vocal cord suggesting recurrent laryngeal nerve injury was confirmed in 10 (3.7% of our total study group). Additionally, 83% of the patients who were referred for otolaryngology consultation received voice treatment. Recovery rate after vocal exercises therapy and injection laryngoplasty was respectively 71% and 33%. CONCLUSIONS: Voice changes after cervical mediastinoscopy is an underreported complication, with an incidence of at least 6.3% in our retrospective study, with persisting complaints in at least 1.5% of patients, leading to mild to moderate disabilities in daily living. These findings highlight the need for appropriate patient education for this underestimated complication, as well as the exploration of possible preventive measures.

RESUMO

A description of pitch reduction thyroplasty has been around for decades, primarily used for high-pitched voice disorders in cisgendered men. Currently, the application of an Isshiki type III thyroplasty and its modifications is mainly used in transgendered men who fail to achieve sufficient pitch reduction from speech therapy and masculinizing gender-affirming hormone therapy. The current state of the procedure with a description of commonly used modifications is reviewed.

RESUMO

OBJECTIVE: People with dysphonia are judged more negatively than peers with normal vocal quality. This preliminary study aims to (1) investigate correlations between both auditory-perceptual and objective measures of vocal quality of dysphonic and non-dysphonic speakers and attitudes of listeners, and (2) discover whether these attitudes towards people with dysphonia vary for different types of stimuli: auditory (A) stimuli and combined auditory-visual (AV) stimuli. Visual (V) stimuli were included as a control condition. METHOD: Ten judges with no experience in the evaluation of dysphonia were asked to rate A, AV and V stimuli of 14 different speakers (10 dysphonic and 4 non-dysphonic speakers) Cognitive attitudes, evaluation of voice characteristics and behavioral attitudes were examined. Pearson and Spearman correlation coefficients were calculated to examine correlations between both Dysphonia Severity Index (DSI) values and perceptual vocal quality as assessed by a speech-language pathologist (PVQSLP) or perceptual vocal quality as assessed by the judges (PVQjudge). Linear mixed model (LMM) analyses were conducted to investigate differences between speakers and stimuli conditions. RESULTS: Statistically significant correlations were found between both perceptual and objective measures of vocal quality and mean attitude scores for A and AV stimuli, indicating increasingly negative attitudes with increasing dysphonia severity. Fewer statistically significant correlations were found for the combined AV stimuli than for A stimuli, and no significant correlations were found for V stimuli. LMM analyses revealed significant group effects for several cognitive attitudes. CONCLUSION: Generally, people with dysphonia are judged more negatively by listeners than peers without dysphonia. However, the findings of this study suggest a positive influence of visual cues on the judges' cognitive and behavioral attitudes towards dysphonic speakers. Further research is needed to investigate the significance of this influence.

RESUMO

This study replicates and extends the recent findings of Lee, Keating, and Kreiman [J. Acoust. Soc. Am. 146(3), 1568-1579 (2019)] on acoustic voice variation in read speech, which showed remarkably similar acoustic voice spaces for groups of female and male talkers and the individual talkers within these groups. Principal component analysis was applied to acoustic indices of voice quality measured from phone conversations for 99/100 of the same talkers studied previously. The acoustic voice spaces derived from spontaneous speech are highly similar to those based on read speech, except that unlike read speech, variability in fundamental frequency accounted for significant acoustic variability. Implications of these findings for prototype models of speaker recognition and discrimination are considered.
