RESUMO

PURPOSE: Literature suggests a dependency of the acoustic metrics, smoothed cepstral peak prominence (CPPS) and harmonics-to-noise ratio (HNR), on human voice loudness and fundamental frequency (F0). Even though this has been explained with different oscillatory patterns of the vocal folds, so far, it has not been specifically investigated. In the present work, the influence of three elicitation levels, calibrated sound pressure level (SPL), F0 and vowel on the electroglottographic (EGG) and time-differentiated EGG (dEGG) metrics hybrid open quotient (OQ), dEGG OQ and peak dEGG, as well as on the acoustic metrics CPPS and HNR, was examined, and their suitability for voice assessment was evaluated. METHOD: In a retrospective study, 29 women with a mean age of 25 years (± 8.9, range: 18-53) diagnosed with structural vocal fold pathologies were examined before and after voice therapy or phonosurgery. Both acoustic and EGG signals were recorded simultaneously during the phonation of the sustained vowels /ɑ/, /i/, and /u/ at three elicited levels of loudness (soft/comfortable/loud) and unconstrained F0 conditions. RESULTS: A linear mixed-model analysis showed a significant effect of elicitation effort levels on peak dEGG, HNR, and CPPS (all p < .01). Calibrated SPL significantly influenced HNR and CPPS (both p < .01). Furthermore, F0 had a significant effect on peak dEGG and CPPS (p < .0001). All metrics showed significant changes with regard to vowel (all p < .05). However, the treatment had no effect on the examined metrics, regardless of the treatment type (surgery vs. voice therapy). CONCLUSIONS: The value of the investigated metrics for voice assessment purposes when sampled without sufficient control of SPL and F0 is limited, in that they are significantly influenced by the phonatory context, be it speech or elicited sustained vowels. Future studies should explore the diagnostic value of new data collation approaches such as voice mapping, which take SPL and F0 effects into account.

RESUMO

PURPOSE: We aimed to evaluate the effect of voice training in patients with head and neck cancer who were undergoing radiotherapy. METHOD: This study used a randomized controlled trial design. IBM SPSS 26.0 was used to randomly divide 74 patients into a control group and an experimental group. The control group followed a swallowing exercises program, and the experimental group additionally received ABCLOVE voice training. Both training programs continued throughout the entire radiotherapy cycle. We compared standardized swallowing assessment (SSA), maximum phonation time (MPT), the Voice Handicap Index-10, and incidence of complications such as difficulty opening the mouth, malnutrition, and aspiration between the two groups at T1 (0 radiotherapy sessions, before radiotherapy), T2 (15-16 radiotherapy sessions, middle of radiotherapy), and T3 (30-32 radiotherapy sessions, end of radiotherapy). RESULTS: 70 participants completed this study. Swallowing function and MPT intergroup and interaction effects were statistically significant between the two groups (P < 0.05). At the end of radiotherapy (T3), the SSA score (20.77 ± 1.96) and MPT (10.98 ± 1.75) s in the experimental group were superior to those in the control group (SSA: 22.06 ± 2.38 and MPT: 9.49±1.41 s), with statistical significance (P<0.05). Moreover, the incidence of malnutrition and aspiration in the experimental group was lower than that in the control group (P < 0.05). CONCLUSION: Voice training can improve swallowing function and MPT and reduce complications related to swallowing disorders in patients with head and neck cancer.

RESUMO

Individuals with Parkinson's disease (PD) experience speech and voice-related symptoms that diminish communication and quality of life. Semi-occluded vocal tract (SOVT) exercises are targeted interventions that, when combined with the positive psychosocial benefits of therapeutic group singing (TGS), may affect outcomes. The purpose of this study was to explore the effectiveness of SOVT exercises, specifically straw phonation combined with TGS, to improve voice quality and mood for individuals with PD. We used a true experimental pretest-posttest between-subjects design (i.e., randomized controlled trial) facilitated by a board-certified music therapist. All participants (N = 27) were randomly assigned to one of three groups (a) straw phonation combined with TGS (SP + TGS, n = 10), (b) TGS (n = 10), and (c) speaking-only control group (n = 7). Participants completed voice recordings for acoustic measures and the Visual Analogue Mood Scale for mood analysis before and after a 30-min intervention. The results demonstrated significant improvement in voice quality evidenced by decreasing Acoustic Voice Quality Index scores following a single session for both SP + TGS and TGS intervention groups when compared to the control. Happiness scores improved in the experimental groups when compared to control. Although not statistically significant, participants in the experimental groups (SP + TGS, TGS) demonstrated better mean mood scores on happiness, anxiety, and angry when compared to control, indicating a positive psychological response to the singing interventions. Overall, this study indicated the effectiveness of SP + TGS and TGS as promising therapeutic interventions for voice quality and mood in individuals with PD.

RESUMO

PURPOSE: The main aim of this study was to investigate the clinical efficacy of speech therapy, delivered via tele-practice to patients with dysphonia. A secondary aim was to verify whether a telerehabilitation-only protocol could have a clinical efficacy similar to a combined telerehabilitation and in-person approach. METHODS: Thirty-two consecutive patients undergoing telerehabilitation for dysphonia were retrospectively considered. Patients were divided into two groups: those who received combined in-person and telerehabilitation treatment, and those who underwent telerehabilitation only. RESULTS: Overall, patients included in this study showed a significant improvement in their VHI-10 scores after treatment (p < 0.001). Such an improvement was also significant in both combined therapy and telerehabilitation only groups (p = 0.019, and p = 0.002, respectively). A significant reduction in general degree of dysphonia (G), roughness (R), breathiness (B) and strain (S) scores (p < 0.001, p = 0.012, p < 0.001, and p < 0.001, respectively) was noticed over the whole sample after treatment. The same parameters showed a significant improvement also in the combined therapy group, while in the telerehabilitation only group, only G, B and S scores significantly improved. Mean phonation time, Jitter and Shimmer values significantly improved in the overall sample as well as in the combined therapy group. A significantly more favorable spectrographic class relative to the vowel /a/ was found after treatment in the whole sample, as well as in both combined therapy and telerehabilitation only groups (p < 0.001, p = 0.002, p = 0.004, respectively). CONCLUSION: This study's results seem to support telerehabilitation as a potentially effective tool to administer speech therapy in dysphonic patients, both as a single modality and in combination with traditional in-person sessions. To better characterize the clinical results of telerehabilitation in dysphonia treatment, large-scale prospective investigations are mandatory.

RESUMO

PURPOSE OF REVIEW: This review addresses the challenges faced by transgender women in achieving congruence between gender identity and voice characteristics and emphasizes the importance of a multidisciplinary approach involving therapeutic and surgical interventions. RECENT FINDINGS: Recent literature on gender-affirming vocal care emphasizes key themes such as assessment, voice feminization therapy, and various surgical techniques, including glottoplasty and its modifications. Recent publications focused on outcomes, duration, and impact on vocal quality and scrutinized complications associated with surgical interventions. SUMMARY: Most publications in the last 18 months advocate for the integration of voice therapy and surgery for optimal outcomes. Utilising a combined approach is significantly more effective in terms of fundamental frequency gain compared to therapy alone. Modified Wendler's glottoplasty remains the preferred and most reliable surgical intervention. However, surgery is not without its complications and vocal trade-offs, in particular, its impact on vocal projection and the risk of long-term dysphonia. Postsurgery rehabilitation improves long-term outcomes. Recent publications on alternative surgical approaches, namely laser reduction glottoplasty and feminization laryngoplasty, show promise but the results are more difficult to generalise. FUTURE DIRECTION: Prospective multicentre studies with standardized protocols are needed to establish best evidence-based practices.

RESUMO

PURPOSE: This systematic review represents an update to previous reviews of the literature addressing behavioral management of respiratory/phonatory dysfunction in individuals with dysarthria due to neurodegenerative disease. METHOD: Multiple electronic database searches and hand searches of prominent speech-language pathology journals were conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. RESULTS: The search yielded 1,525 articles, from which 88 met inclusion criteria and were reviewed by two blinded co-investigators. A large range of therapeutic approaches have been added to the evidence base since the last review, including expiratory muscle strength training, singing, and computer- and device-driven programs, as well as a variety of treatment modalities, including teletherapy. Evidence for treatment in several different population groups-including cerebellar ataxia, myotonic dystrophy, autosomal recessive spastic ataxia of Charlevoix-Saguenay, Huntington's disease, multiple system atrophy, and Lewy body dementia-were added to the current review. Synthesis of evidence quality provided strong evidence in support of only one behavioral intervention: Lee Silverman Voice Treatment Program (LSVT LOUD) in people with Parkinson's disease. No other treatment approach or population included in this review demonstrated more than limited evidence, reflecting that these approaches/populations require urgent further examination. CONCLUSION: Suggestions about where future research efforts could be significantly strengthened and how clinicians can apply research findings to their practice are provided.

RESUMO

PURPOSE: The present study aimed at assessing the efficacy of remote voice therapy (telepractice) implemented with Shaker Medic Plus device in subjects with vocal fatigue. METHOD: Thirty-six participants were initially enrolled in this study. Twenty-four participants with vocal fatigue were finally randomly assigned to one of two treatment groups: (a) voice treatment with Shaker Medic Plus device plus vocal hygiene program (n = 12) and (b) voice treatment with water resistance therapy (WRT) plus vocal hygiene program (n = 12). Laryngoscopic assessment was conducted on all subjects. Before and after voice therapy, participants underwent (a) self-assessment of voice: Vocal Fatigue Index and Vocal Tract Discomfort Scale and (b) instrumental assessment with aerodynamic, acoustic, and electroglottographic measures. The treatment period included six voice therapy sessions within 6 weeks. Each session lasted 30 min. For both groups, exercises consisted of a sequence of nine phonatory tasks performed with Shaker Medic Plus (experimental group) and WRT (control group). Comparisons for all variables were performed between the experimental group and control group. RESULTS: Significant improvements were found for self-reported variables when comparing pre- and postmeasures for both groups. No significant differences were found when comparing groups. No significant main effects or interactions were observed for any of the observed instrumental variables. CONCLUSIONS: Remote physiologic voice therapy with Shaker Medic Plus device and water resistance therapy seem to be both effective to improve voice in subjects diagnosed with vocal fatigue. No differences should be expected between these therapeutic protocols when treating patients with vocal fatigue. Moreover, both are effective at reducing tiredness of voice, voice avoidance, physical discomfort associated with voicing, subjective perception of sensory discomfort in throat, and reduction of physical, emotional, and functional impact of voice problems.

RESUMO

An incompatible voice with one's own identity is a theme frequently pointed out by the transgender population in speech therapy sessions. Speech therapy is a technique that allows the adjustment of the speaker's voice within a range of possibilities. The speech-language pathologist's role is to provide training, guidance, and counseling to this population, taking into account the specificities of each individual. In light of this, this study aims to report the experience of undergraduate students and speech-language professionals in providing care to the transgender population in a communication laboratory. Initially, key concepts, such as the differences between sex, gender, gender identity, and sexual orientation, are presented. Topics addressed include the violence suffered by the transgender population, the pursuit of vocal adaptation, the creation and development of the communication clinic, the support and assistance provided by professionals to the transgender population and their families, as well as the procedures adopted by the clinic. Among the conclusions, it is highlighted that speech therapy has demonstrated the importance of individual-centered care, legitimizing the guarantee of promoting the users' health. Furthermore, the importance of the speech-language professional in the vocal and communicative improvement of this population, which is often stigmatized, is emphasized (AU).


Voz incompatível com a própria identidade é um tema frequentemente apontado pela população transgênera em atendimentos fonoaudiológicos. A fonoterapia é uma técnica que permite a adequação da voz do falante, dentro de um campo de possibilidades. Ao fonoaudiólogo cabe o treinamento, a orientação e o aconselhamento dessa população, levando em conta as especificidades de cada indivíduo. Diante disso, este estudo tem como objetivo relatar a experiência de estudantes de graduação e profissionais de Fonoaudiologia no atendimento voltado à população transgênera em um laboratório de comunicação. Inicialmente são apresentados conceitos-chave, tais como as diferenças entre sexo, gênero, identidade de gênero, e orientação sexual. São abordados temas como a violência sofrida pela população trans, a busca pela adequação vocal, a criação e o desenvolvimento do ambulatório de comunicação, o acolhimento e o suporte prestado pelos profissionais à população trans e a seus familiares, além dos procedimentos adotados pelo ambulatório. Dentre as conclusões, destaca-se que a assistência fonoaudiológica tem mostrado a importância do cuidado centrado no indivíduo, legitimando a garantia da promoção de saúde dos usuários. Ademais, é destacada a importância do profissional de fonoaudiologia no aprimoramento vocal e comunicativo dessa população que é frequentemente estigmatizada (AU).

RESUMO

PURPOSE: Although speech-language pathologists have provided gender-affirming voice training for trans women since the 1970s, evidence for this training's effectiveness remains weak. Our study aimed to redress limitations of earlier studies and evaluate voice training effects on outcomes important to trans women. METHOD: Seventy-four trans women (19-54 years old) who wanted a more female-sounding voice were recruited through two health facilities and provided with an eight- to 12-session voice training program based on contemporary literature, usual clinical practice, and client-centered care principles. Self-reported outcomes and an audio-recorded reading sample were collected 3 months before, immediately before and after, and 3 months after training. Forty cisgender speakers were audio-recorded reading the same sample material as comparison voices. Seventy-nine naive listeners made gender-related voice ratings of an extract from these audio recordings. Training effectiveness was evaluated using group-level analyses (linear mixed-effects models) and individual-level analyses to establish what proportion of participants improved to a predetermined relevant degree. RESULTS: Group-level analyses demonstrated positive training effects, maintained 3 months posttraining, for trans women's vocal satisfaction, perceptions of voice-related social participation, and self- and listener perceptions of their voices. Individual-level analyses also demonstrated positive effects. Two thirds of trans women increased vocal satisfaction to a relevant degree, one third who reported restricted social participation before training reduced this restriction to a relevant degree, and all were rated more female-sounding after training (although not all to a relevant degree). CONCLUSIONS: All trans women participants made progress toward their voice goals and maintained those gains at follow-up. These findings provide evidence that gender-affirming speech-language pathology services warrant prioritization. Further research is warranted to investigate factors predicting outcomes of voice training for trans women.

RESUMO

PURPOSE: This study evaluated the efficacy of a 4-week straw phonation in water (SPW) exercise program on aging-related vocal fold atrophy (VFA), with a secondary objective to examine the immediate effects of SPW exercises. METHOD: Thirty-eight older adults aged 60 years and above formally diagnosed with aging-related VFA were randomly assigned into an experimental group undergoing SPW exercises with an 8-cm depth of straw submersion into water for 4 weeks plus vocal hygiene practice (n = 20), and a control group with only vocal hygiene practice (n = 18). Outcome measures included laryngeal endoscopic measures of glottal gap, auditory-perceptual ratings of voice quality, acoustic measures, aerodynamic measures, and standardized self-assessment questionnaire scores. An additional round of acoustic and aerodynamic assessment following 20 min of SPW exercises was conducted to examine the immediate effects. RESULTS: Significant improvements in normalized glottal gap area, perceptual rating of breathiness, smoothed cepstral peak prominence, harmonics-to-noise ratio (HNR), mean oral airflow, subglottal pressure and laryngeal airway resistance at comfortable loudness, Voice-related Quality of Life scores, and Chinese Vocal Fatigue Index Factor 3 scores were observed in the experimental group relative to the control group. There were also significant immediate effects for HNR, mean oral airflow, subglottal pressure, and laryngeal airway resistance. CONCLUSIONS: These findings suggested significant immediate improvements in vocal function following SPW exercises, with additional significant improvements in vocal function as well as significant improvements in quality of life following the 4-week SPW exercise program. Further studies with more long-term follow-up are recommended to better understand the efficacy of SPW exercises with deep levels of straw submersion into water as an effective clinical option for the management of hypofunctional dysphonia associated with aging-related VFA.

RESUMO

The implantation of a voice prosthesis has become a standard procedure during a laryngectomy. A voice prostheses enables patients to develop speech shortly after surgery, which strongly improves rehabilitation and quality of life.The lifetime of a voice prosthesis is limited and highly variable due to different causes. A replacement is usually necessary several times a year and can easily been done in an outpatient setting with surface anesthesia. In some cases, replacing the prosthesis becomes difficult. This article will take a closer look at different reasons that can lead to difficulties in prostheses replacement and discuss possible solutions, thereby focusing especially on a retrograde technique. The aim of this article is to help colleagues that already have experience with voice prostheses and want to expand their therapeutic armamentarium.

RESUMO

PURPOSE: Dysphonia is a common symptom due to the coronavirus disease of the 2019 (COVID-19) infection. Nonetheless, it is often underestimated for its impact on human's health. We conducted this first study to investigate the global prevalence of COVID-related dysphonia as well as related clinical factors during acute COVID-19 infection, and after a mid- to long-term follow-up following the recovery. METHODS: Five electronic databases including PubMed, Embase, ScienceDirect, the Cochrane Library, and Web of Science were systematically searched for relevant articles until Dec, 2022, and the reference of the enrolled studies were also reviewed. Dysphonia prevalence during and after COVID-19 infection, and voice-related clinical factors were analyzed; the random-effects model was adopted for meta-analysis. The one-study-removal method was used for sensitivity analysis. Publication bias was determined with funnel plots and Egger's tests. RESULTS: Twenty-one articles comprising 13,948 patients were identified. The weighted prevalence of COVID-related dysphonia during infection was 25.1 % (95 % CI: 14.9 to 39.0 %), and male was significantly associated with lower dysphonia prevalence (coefficients: -0.116, 95 % CI: -0.196 to -0.036; P = .004) during this period. Besides, after recovery, the weighted prevalence of COVID-related dysphonia declined to 17.1 % (95 % CI: 11.0 to 25.8 %). 20.1 % (95 % CI: 8.6 to 40.2 %) of the total patients experienced long-COVID dysphonia. CONCLUSIONS: A quarter of the COVID-19 patients, especially female, suffered from voice impairment during infection, and approximately 70 % of these dysphonic patients kept experiencing long-lasting voice sequelae, which should be noticed by global physicians.

RESUMO

Proposta recente de apresentação de Programa de Condicionamento Vocal e Respiratório (CVR I) incentivou a continuidade (CVR II), considerando novas estratégias de treinamento muscular vocal e respiratório que pudessem contribuir para melhor desempenho de profissionais da voz. Para a condução da ação, mais uma vez, houve a participação integrada de fonoaudiólogos e fisioterapeutas e, no papel de participantes, profissionais da voz. Planejada para dez encontros, em que dois deles (início e fim) foram destinados à coleta de dados, a proposta teve como objetivo aumentar ainda mais a resistência vocal e respiratória dos participantes, promovendo melhor rendimento profissional. Exercícios de trato vocal semiocluído e respiratórios foram realizados com o uso dos incentivadores denominados New Shaker® e Respiron Athletic 2®. Trata-se de mais uma experiência relatada na direção de convocar outros profissionais a colocarem em prática ações para o condicionamento vocal e respiratório de profissionais da voz. O uso de incentivadores respiratórios e a parceria com a Fisioterapia são apresentados e recomendados para melhor entendimento e consequente atendimento das questões da voz e da respiração. (AU)


This is a continuation (VRC II) of a recent proposal to present a Vocal and Respiratory Conditioning (VRC I) Program using new vocal and respiratory muscle training strategies aimed at contributing to a better performance of voice professionals. Once again, the initiative included the integrated participation of speech-language pathologists and physiotherapists, as well as voice professionals as participants. Ten meetings were planned in the initial proposal, with the first and last meeting focused on data collection, the proposal aimed to further increase the vocal and respiratory resistance of the participants, promoting better professional performance. Semi-occluded vocal tract and respiratory exercises were performed with using the New Shaker® and Respiron Athletic 2® boosters. This is an experience reported in order to encourage other professionals to put into practice actions for vocal and respiratory conditioning. The use of respiratory boosters and the partnership with Physiotherapy are recommended, aiming at a better understanding and consequent care of voice and breathing issues in voice professionals.

RESUMO

Objectives: This investigation aimed to propose a new rehabilitation technique that combines voice exercises and instrumental postural rehabilitation for patients with muscle tension dysphonia (MTD). Methods: We enrolled nine dysphonic patients (8 women and 1 man, aged 22-55 years). Voice assessment included strobovideolaryngoscopy, Maximum Phonation Time (MPT), perceptual evaluation by GRBAS scale and patient's self-rating by Italian version of the Voice Handicap Index (VHI). Vestibular function was evaluated by the Bed Side Examination and Video Head Impulse test (VHIT). Postural control was evaluated by Dynamic Posturography (DP) using the Sensory Organization Test (SOT) and analysing the Equilibrium Score (ES) and balance subsystems (somatosensorial, visual, vestibular). Results: All cases underwent different types of voice exercises combined with balance training based on NeuroCom Balance Master Protocols, once a week for six 35-minutes sessions. After therapy, an improvement in MPT, VHI, GRBAS scores and endoscopic laryngeal features was obtained. DP results at baseline were normal and after therapy we showed a slight improvement of ES (somatosensorial and visual components). Conclusions: A combined rehabilitation technique for MTD, by improving the attention to postural control, allows for significant improvement in vocal symptoms.

RESUMO

PURPOSE: Limited research has examined the suitability of crowdsourced ratings to measure treatment effects in speakers with Parkinson's disease (PD), particularly for constructs such as voice quality. This study obtained measures of reliability and validity for crowdsourced listeners' ratings of voice quality in speech samples from a published study. We also investigated whether aggregated listener ratings would replicate the original study's findings of treatment effects based on the Acoustic Voice Quality Index (AVQI) measure. METHOD: This study reports a secondary outcome measure of a randomized controlled trial with speakers with dysarthria associated with PD, including two active comparators (Lee Silverman Voice Treatment [LSVT LOUD] and LSVT ARTIC), an inactive comparator (untreated PD), and a healthy control group. Speech samples from three time points (pretreatment, posttreatment, and 6-month follow-up) were presented in random order for rating as "typical" or "atypical" with respect to voice quality. Untrained listeners were recruited through the Amazon Mechanical Turk crowdsourcing platform until each sample had at least 25 ratings. RESULTS: Intrarater reliability for tokens presented repeatedly was substantial (Cohen's κ = .65-.70), and interrater agreement significantly exceeded chance level. There was a significant correlation of moderate magnitude between the AVQI and the proportion of listeners classifying a given sample as "typical." Consistent with the original study, we found a significant interaction between group and time point, with the LSVT LOUD group alone showing significantly higher perceptually rated voice quality at posttreatment and follow-up relative to the pretreatment time point. CONCLUSIONS: These results suggest that crowdsourcing can be a valid means to evaluate clinical speech samples, even for less familiar constructs such as voice quality. The findings also replicate the results of the study by Moya-Galé et al. (2022) and support their functional relevance by demonstrating that the effects of treatment measured acoustically in that study are perceptually apparent to everyday listeners.

RESUMO

INTRODUCTION: Semi-occluded vocal tract exercises (SOVTEs) are frequently used exercises in voice therapy. An important shortcoming to most SOVTEs is the inability to include continuous speech in these exercises. A variation of water-resistance therapy (WRT), during which a patient phonates through a resonance tube ending in water, was developed to include continuous speech: the semi-occluded water resistance ventilation mask (SOVM-WR). The current study investigated the immediate effects of this innovative technique on vocal outcomes of women with dysphonia. METHODS: A pretest-posttest randomized controlled trial was performed. Twenty female participants were randomly assigned to the experimental SOVM-WR group or the WRT (control) group. A blinded multidimensional voice assessment was conducted before and after a 30-minute therapy session with the assigned technique. RESULTS: No significant changes were found in acoustic or auditory-perceptual vocal outcomes in either of the groups, except for a significant increase in lowest frequency in both groups. Patient-reported outcomes (PROMs) showed significant improvements of vocal comfort, vocal effort, and voice quality in both groups, and participants indicated that they would use the techniques at home. CONCLUSIONS: The similar results of the SOVM-WR to WRT and promising PROMs confirm its suitability as an alternative to the latter technique. Potential reasons for a lack of improvement of objective and auditory-perceptual vocal outcomes are vocal fatigue, tube dimensions and immersion, and the small sample size. Large-scale and longitudinal research is needed to examine whether the SOVM-WR has a higher transfer to spontaneous speech than WRT after a full therapy program.

RESUMO

BACKGROUND: Many amateur singers enjoy singing in choirs. They are likely to lack the training and expertise of professional singers and this may have an impact on their vocal health. AIMS: To assess the experiences of amateur singers, their use of warm-up and cool-down sessions, their vocal health, their sources of help and advice and their reactions to receiving a diagnosis and treatment. METHODS AND PROCEDURES: A questionnaire was sent to amateur choir singers. Quantitative data on their use of warm-up and cool-down activities were collected and the singers rated how frequently they experienced adverse voice symptoms after singing. Qualitative data were collected from singers who had sought advice about their voice and from those who had received a diagnosis and treatment. OUTCOME AND RESULTS: Most choirs used warm-up sessions but few used cool-down. Singers who participated in choir warm-ups experienced significantly less vocal symptoms. Individual warm-ups were ineffective. Singers who had previously had a diagnosis continued to have significantly higher symptom scores. A quarter of the singers who had neither sought help nor had a diagnosis had high scores. Singers appeared uncertain about who to consult for help. Those who saw a speech and language therapist were much more likely to receive a diagnosis and treatment either by the therapist or by referral to an ear, nose and throat specialist. Those receiving treatment were mainly positive about it and likely to complete a course of therapy. CONCLUSIONS AND IMPLICATIONS: Warm-up sessions performed by choirs are helpful in avoiding voice symptoms and are recommended. The presence of singers who are unaware of potential damage to their voices is a concern. A simple rating system, as used in this research, may act to alert them to the dangers. Choir leaders could be more active in advising singers and refer them to professionals where necessary. Speech and language therapists appear more sensitive to their problems and could be a first point of contact. WHAT THIS PAPER ADDS: What is already known on this subject Poor vocal health may occur in amateur singers and lead to voice disorders which will reduce the demonstrated benefits of regular singing. They may be less aware than professional singers of potential hazards and may not know how to sing in a way that ensures good vocal health. There has been less research on the extent of voice problems in amateurs or of the actions they may take to resolve the vocal difficulties they encounter. What this paper adds to the existing knowledge This survey demonstrates that choir warm-ups were effective in helping to avoid common symptoms associated with voice problems. A large minority of singers who had not sought help for voice problems had high symptom scores on our assessment. Singers frequently turned to a singing teacher for help. Those who consulted a speech and language therapist were much more likely to be referred for further investigation and treatment. What are the potential or actual clinical implications of this work? We present a simple subjective measure of symptom severity which succeeds in distinguishing between singers who warm up their voices and those who do not and between singers who have received a past diagnosis and those who have not. There are a number of indications in this research that amateur singers are unsure if they need help and are uncertain who can offer it. In these circumstances the use of a simple measure of the severity of vocal abuse may be useful.

RESUMO

BACKGROUND: A promising way to obtain vocal economy and efficiency is by semi-occluding the vocal tract while phonating. Current knowledge about the immediate effects of semi-occluded vocal tract (SOVT) phonation on the laryngeal function and configuration is based mainly on computer modelling or excised larynges studies. In in vivo SOVT studies, electroglottography (EGG) has been the most commonly used laryngeal outcome, showing contradictory results between studies. Therefore, exploring these aspects by direct visualisation of the human larynx during SOVT phonation using strobovideolaryngoscopy (SVL) is needed. AIMS: The aim of this study was to investigate and compare the immediate effects of straw phonation (SP) in air, SP in 2 cm water, and SP in 5 cm water (with stirring straws), on the laryngeal function and configuration of a homogeneous group of vocally healthy female speech-language pathology students, visualised with flexible SVL. METHODS & PROCEDURE: A randomised controlled trial was used. Fifty-two female speech-language pathology students (mean age: 18.7 years, SD: 0.6) were assigned randomly to one of three experimental groups or a control group: (1) SP in air, (2) SP in 2 cm water, (3) SP in 5 cm water or (4) [u] phonation with similar soft onset and slightly pursed lips as in SP but without a straw (control group). The participants underwent flexible SVL during habitual [u] phonation, followed by the specific SOVT exercise of their group assignment. All video samples were evaluated randomly and blindly by two experienced investigators using the Voice-Vibratory Assessment with Laryngeal Imaging (VALI) rating form, first independently and then by consensus. OUTCOME & RESULTS: Compared to habitual phonation, the vibrational amplitude decreased during SP in 5 cm water and SP in 2 cm water, being more prominent in the first, more flow-resistant exercise. The mucosal wave also decreased during SP in 5 cm water. The anteroposterior (AP) supraglottic compression similarly increased during SP in air, SP in 2 cm water, and SP in 5 cm water. Further, a rise in mediolateral (ML) compression and a decrease in phase symmetry and regularity were found during SP in 2 cm water. A similar decrease in regularity was observed during SP in 5 cm water. CONCLUSIONS & IMPLICATIONS: Both SP in air and SP in water cause positive immediate laryngeal effects for voice training opportunities. More AP supraglottic activity found during each SP exercise might indicate epilarynx narrowing, an economic phenomenon associated with SOVT. Immersing the straw in water additionally diminished the vibrational amplitude, lowering vocal fold impact stress and risk for phonotrauma during the exercise. The decreased regularity of the vibrational cycles during SP in water might be due to the varying back pressure created by the water bubbling. The impact of SP in water on ML supraglottic compression needs further investigation. WHAT THIS PAPER ADDS: What is already known on the subject A promising way to obtain vocal economy and efficiency is by semi-occluding the vocal tract while phonating. Current knowledge about the immediate effects of semi-occluded vocal tract (SOVT) phonation on the laryngeal function and configuration is based mainly on computer modelling or excised larynges studies.

Therefore, exploring these aspects by direct visualisation of the human larynx during SOVT phonation using strobovideolaryngoscopy (SVL) is needed. What this paper adds to existing knowledge Group results of the current study generally support earlier computer modelling and in vivo studies, strengthening the current SOVT knowledge. Both SP in air and SP in water cause positive immediate laryngeal effects for voice training opportunities. More anteroposterior (AP) supraglottic activity found during each SP exercise might indicate epilarynx narrowing, an economic phenomenon associated with SOVT. Immersing the straw in water additionally diminished the vibrational amplitude, lowering vocal fold impact stress and risk for phonotrauma during the exercise. The decreased regularity of the vibrational cycles during SP in water might be due to the varying back pressure created by the water bubbling. The impact of SP in water on ML supraglottic compression needs further investigation. What are the potential or actual clinical implications of this work? Current results support that both SP in air and SP in water can be useful exercises in voice training. SP in water has shown the additional gain of lowering the vibrational amplitude during the exercise, hence supporting its appropriateness for vocal warm-ups by minimising vocal fold impact stress and the risk of phonotrauma. In the future, large-scale randomised controlled trials in other subgroups of voice users, including dysphonic patients, are needed to support evidence-based practice. SVL can facilitate the search for individualised training and therapy approaches.

RESUMO

INTRODUCTION: Indirect vocal therapy (IVT) has tools that aim to modify an individual's behavior, emotional factors, and physical environment for restoring vocal quality. Then, vocal health guidance may promote the desire for caring about the voice and prevent or treat behavioral dysphonia. However, studies that used parts of IVT have shown conflicting results. Hence, the main objective of this study was to introduce an IVT program based on the taxonomy of Van Stan et al. [Am J Speech Lang Pathol. 2015;24(2):101-25]. The second objective of this study was to analyze the preliminary effects of the IVT program on vocal comfort through the self-assessment of vocal fatigue, vocal symptoms, vocal handicap, and vocal quality in patients diagnosed with behavioral dysphonia. METHOD: This is an experimental, analytical, and prospective pilot study. Nine participants (five women; four men) aged between 18 and 50 years with behavioral dysphonia participated in this study. They underwent the IVT program with guidance about vocal health, general health, emotional factors, and motivation. The therapy was implemented twice per week, totalizing eight sessions, each lasting 35 min. Participants were assessed before therapy started (M1), after it ended (M2), and 1 month after as a follow-up (M3). As assessment, participants filled in the Vocal Fatigue Index (VFI), Voice Symptoms Scale (VoiSS), and Vocal Handicap Index-30 (VHI-30). Additionally, they had their voices recorded for acoustic measures (i.e., cepstral peak prominence-smoothed, alpha ratio, and L1-L0) and auditory-perceptual analysis using the GRBASI scale. RESULTS: The acoustic measures and auditory-perceptual analysis showed no significant differences between the assessment moments. The auditory-perceptual analysis showed a mild deviation in participants' vocal quality. The participants' scores of the VFI, VoiSS, and VHI were lower in M2 and remained lower in M3. CONCLUSION: The IVT program had positive results in voice-related self-assessment and vocal comfort. However, further studies are necessary to elucidate its effects on the vocal quality of participants with behavioral dysphonia.
