RESUMO

Coaching is one of the most common words in our modern vocabulary and has many meanings depending on the setting in which it is used. Coaching facilitates positive changes to achieve a goal, usually through indirect approaches, including improving an individual's outlook on their behaviors or attitudes. Its application has spread beyond the corporate world, and many medical specialties use coaching principles. The goals of this article are to introduce coaching as a profession, and to explore the function of a vocal coach to improve communicative and vocal performance. Moreover, differences between voice therapy and voice training are highlighted, including the principles subjacent to these interventions and the use of coaching strategies. Four strategies of professional coach practitioners adapted to the training and therapy of the voice with applications to both are described. These are: powerful questions, active listening, changing habits, and implementation intention. The use of these strategies may help individuals to achieve high voice performance. Most importantly, the speech-language pathologist voice specialist can apply these strategies particularly in cases of behavioral dysphonias, which can be resistant to traditional voice therapy.

RESUMO

OBJECTIVE: To propose a short instrument for the screening of dysphonia in the Brazilian population through the investigation of traditional voice self-assessment instrument items. METHODS: We analyzed the medical records of 139 individuals with an average age of 37.4 years and a minimum and maximum age of 18 and 77 years, respectively. The participants were classified as dysphonic (D) or non-dysphonic (ND) according to an analysis of the combination of vocal complaints and laryngological reports. Responses to the items of the following self-assessment instruments were collected: the Questionário de Qualidade de Vida em Voz - QVV (Voice-Related Quality of Life - V-RQOL), the Índice de Desvantagem Vocal - IDV (Voice Handicap Index - VHI) and the Escala de Sintomas Vocais - ESV (Voice Symptom Scale - VoiSS). These items were analyzed regarding their predictive capacities for dysphonia through logistic regression models. RESULTS: The model containing items of the QVV was not observed to be valid. The model for the IDV produced a set of three items (10, 13, and 14), and the ESV model showed two items (4 and 20) to be significant. A Global model combining the previous models shows that items "I feel I have to force my speech" from the IDV and "Is your voice hoarse?" from the ESV are the most significant in the classification of the presence of dysphonia. This decision-making model was considered the most efficient to identify the dysphonia, with the highest level of accuracy compared to the other models investigated (83.4%). CONCLUSION: Dysphonia screening can be performed using a simple, rapid protocol with a high-efficiency index that includes two items taken from traditional voice self-assessment instruments.

RESUMO

OBJECTIVE: To assess the concurrent validity and the diagnostic accuracy of the Acoustic Breathiness Index (ABI) in Brazilian Portuguese. METHODS: The counting numbers 1-20 and the vowel /a/ of 150 subjects were recorded (37 vocally healthy and 113 with dysphonia). The analyzed samples were the counting number 1-11 and 3 s of the sustained vowel. Nine voice specialists performed the perceptual judgment of the degree of breathiness. The Spearman Correlation and the receiver operating characteristic (ROC) curve were used to assess ABI's concurrent validity and diagnosis accuracy. RESULTS: Results from five listeners were chosen for the study analyses due to moderate and substantial intra-rater reliability (Cohen's Kappa values = 0.520-0.772) and moderate inter-rater reliability (Fleiss Kappa = 0.353). The ABI presented a high concurrent validity (r = 0.746); 55.6% of the breathiness vocal deviation can be explained by the acoustic analysis (r 2 = 0.556). The ROC curve presented good diagnostic accuracy (85.2%). At a threshold of 2.94, the sensitivity was 75.3% and the specificity was 93.4%. CONCLUSION: The ABI is a valid tool for screening and patient's follow-up regarding breathy vocal qualities in the Brazilian Portuguese language.

RESUMO

PURPOSE: To verify the association between laryngopharyngeal reflux (LPR) with age, gender, vocal deviation and voice complaints. METHODS: The study included patients between 18 and 70 years old, referred to the Otorhinolaryngology service for complaints of voice or reflux, of both sexes. Endolaryngeal findings were classified using the Reflux Finding Score (RFS) scale. The presence or absence of vocal and reflux complaints was verified and correlated with the RFS classification. On the same date, they were submitted to sustained vowel voice recording and chained speech. The auditory-perceptual assessment was performed by a speech therapist, classifying the general degree of vocal deviation based on the GRBASI scale. RESULTS: Ninety-seven patients were evaluated, with a mean age of 42. 6 years, 62. 3% female, and mean RFS scores of 6. 26 points. Among the patients, 48 subjects had vocal complaints, 34 women with a mean age of 44. 9 years and an average RFS score of 6. 94 points. The other 49 individuals had no vocal complaints, and of these 27 were women, with a mean age of 41. 2 years and a mean RFS score of 5. 5 points. The variables "reflux complaint", "vocal complaint" and age were the ones that most correlated with the RFS scale scores. CONCLUSION: There is a relationship among reflux complaints, laryngeal findings and vocal complaint.

RESUMO

OBJECTIVE: To evaluate the Acoustic Voice Quality Index (AVQI) and its isolated acoustic measures accuracy in discriminating voices with different degrees of deviation. METHODS: Two hundred and fifty-eight voice samples (160 dysphonic; 98 vocally healthy). Information regarding acoustic analysis and overall degree of deviation (G) were considered. The acoustic analysis consisted of the AVQI total score and its isolated acoustic measures: smoothed cepstral peak prominence (CPPs); harmonic-to-noise ratio (HNR); shimmer local and dB (Shim, ShdB); the general slope of the spectrum (Slope) and tilt of the regression line through the spectrum (Tilt). The auditory-perceptual judgment was the median G score of five voice specialists (Cohen's = 0.605-0.773; Fleiss = 0.370). Quadratic discriminant analysis and accuracy, sensitivity, and specificity of performance measures were used to investigate the discriminatory power of these measures. RESULTS: AVQI presented acceptable accuracy to differentiate voices with no vocal deviation and with vocal deviation (73.9%) and among the degrees of deviation (mild vs. moderate = 70.49%; mild vs. moderate = 71.39%; moderate vs. severe = 87.5%). No isolated acoustic measurement was consistent with differentiating voice quality among all degrees of deviation. A combination of five acoustic measures (CPPs, HNR, ShdB, Slope, Tilt) had the highest accuracy to differentiate between healthy and deviated voice (75.55%). Shimmer was more accurate to discriminate between voices with mild, moderate, and severe deviation; almost all isolated acoustic measurements were accurate to discriminate voices with moderate and severe deviation. The combination of acoustic measures presented higher accuracy (mild vs. moderate = 70.21%-74.29%; mild vs. moderate = 71.53%-76.11%; moderate vs. severe = 86%-95.50%). CONCLUSION: AVQI is an accepted tool to discriminate among different degrees of vocal deviation, and more accurate between voices with moderate and severe deviations. Isolated acoustic measures perform better when discriminating voices with a higher degree of deviation. A combination of acoustic parameters, with the same weight, is more accurate to discriminate different degrees of deviation, however, not consistent.

RESUMO

INTRODUCTION: Since the beginning of the new pandemic, COVID-19 health services have had to face a new scenario. Voice therapy faces a double challenge, interventions using telepractice, and delivering rehabilitation services to a growing population of patients at risk of functional impairment related to the COVID-19 disease. Moreover, as COVID-19 is transmitted through droplets, it is critical to understand how to mitigate these risks during assessment and treatment. OBJECTIVE: To promote safety, and effective clinical practice to voice assessment and rehabilitation in the pandemic COVID-19 context for speech-language pathologists. METHODS: A group of 11 experts in voice and swallowing disorders from five different countries conducted a consensus recommendation following the American Academy of Otolaryngology-Head and Neck Surgery rules building a clinical guide for speech-language pathologists during this pandemic context. RESULTS: The clinical guide provides 65 recommendations for clinicians in the management of voice disorders during the pandemic and includes advice from assessment, direct treatment, telepractice, and teamwork. The consensus was reached 95% for all topics. CONCLUSION: This guideline should be taken only as recommendation; each clinician must attempt to mitigate the risk of infection and achieve the best therapeutic results taking into account the patient's particular reality.

RESUMO

OBJECTIVE: To investigate the psychometric properties of the Voice-Related Quality of Life (V-RQOL) questionnaire in Brazilian Portuguese by assessing its reliability and conducting exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). METHODS: This research was carried out in two stages: (1) a document-based retrospective approach and (2) a field study step. The study included 566 dysphonic and vocally healthy individuals. For data collection, the Vocal Screening Protocol and the V-RQOL questionnaire were used, and these measures were later statistically analyzed through descriptive analysis, reliability tests, CFA, and EFA. Ethical issues were considered. RESULTS: A Cronbach's alpha coefficient of 0.916 was observed, indicating good internal consistency for the V-RQOL questionnaire. The item-total correlation coefficient indicated that the items had good correlation with each other and with the construct, with values higher than 0.30. EFA was performed based on the Kaiser-Meyer-Olkin index and Bartlett's test of sphericity, which indicated the adequacy of the tested sample. The items presented commonality of >0.30 and satisfactory factor loadings, resulting in a single factor. The unifactorial structure of the V-RQOL questionnaire was confirmed by CFA. CONCLUSION: EFA and CFA indicated that a single factor should be adopted to encompass all the items of the V-RQOL questionnaire.

RESUMO

OBJECTIVE: To verify the relationship between self-regulation and voice behavior according to national and international literature. METHODS: A literature survey was performed using the PubMed, LILACS, and SciELO databases. The search terms used were the following: self-regulation, self-control, combined with voice, voice disorders, and dysphonia, in Portuguese, English, and Spanish. Articles that addressed self-regulation and voice behavior or voice disorders published in English, Spanish, or Portuguese were included, without restriction of date. The variables preselected for the data organization were authors, database, country, impact factor, journal, type of study, sample size, sample characteristics, methods for data collection, group comparison, objective, and outcome. RESULTS: A total of 10,176 articles were identified in the databases, of which 10 were selected based on title, read in full, and kept for data analysis. The studies were found predominantly in American journals and were published between 2013 and 2019. The United States published most articles, and the predominant methodological aspect was observational and cross-sectional. CONCLUSION: Despite the small number of articles, the studies analyzed can show self-regulation as an important factor in vocal behavior and call attention to its performance in voice disorders.

RESUMO

INTRODUCTION: The Consensus Auditory Perceptual Evaluation of Voice (CAPE-V) scale is a modern, clinical-scientific approach to voice analysis. It has been translated and culturally adapted to Brazilian Portuguese, but it still lacks validation. OBJECTIVE: To validate the Brazilian Portuguese version of the CAPE-V scale using the previously translated and culturally adapted version. METHOD: Forty voice samples were selected (30 dysphonic, 10 nondysphonic), and the degree of vocal deviation was evaluated by a committee of three voice specialists. Nine voice specialists judged the 40 voice samples plus 20% repetition (total of 48 samples) using the CAPE-V. To ensure construct validity of the CAPE-V, its analysis was compared to the Grade-Roughness-Breathiness-Asthenia-Strain (GRBAS) scale that was performed 48-72 hours later. Finally, the intra- and inter-rater reliability values were verified and the correlation between the nine judges and the previously defined evaluation was analyzed. RESULTS: The Brazilian CAPE-V presented significant intra (0.860-0.997) and inter-rater reliability values (0.707-0.964) for the overall degree and strong correlation with GRBAS (above 0.828). Deviant voice quality had greater consensus among raters than normal voices. A strong correlation was observed between the analysis of the nine raters and that of the committee. CONCLUSION: CAPE-V is an important diagnostic instrument that contributes to the standardization of vocal quality evaluation in several languages, including Brazilian Portuguese. Thus, its usefulness is neither related to a single language nor to a single set of raters.

RESUMO

The goal of this study is to compare and combine different acoustic features in discriminating subjects with and without voice disorders. A database of 484 adult patients participated in the research. All subjects recorded a sustained vowel /Ɛ/ and underwent a laryngoscopic examination of the larynx. From the results of the laryngeal examination performed by a physician and the auditory-perceptual judgment performed by a Speech-Language Pathologist, the subjects were allocated to the group with (n = 52) and without (n = 432) voice disorder. Four types of acoustic features were used: traditional measures, cepstral measures, nonlinear measures, and recurrence quantification measures. Recordings comprised the emission of the vowel /ε/. Quadratic discriminant analysis was used as classifier. Individual features in the context of traditional, cepstral, and recurrence quantification measures achieved an acceptable performance of ≥70%. Combination of measures improved the classifier performance. The best classification result (86.43% accuracy) was obtained by combining traditional linear and recurrence quantification measures. Results shown that Traditional, Cepstral, and recurrence quantification measures are promising features that capture meaningful information about voice production, which provides good classification performances. The findings of this study can be used to develop a computational tool for voice disorders diagnosis and monitoring.

RESUMO

OBJECTIVE: To analyze the variations that different voice sample length (VSL) has on the perceived degree of voice quality deviation and on the Acoustic Voice Quality Index (AVQI) accuracy. METHODS: Voices of 71 subjects (53 dysphonic; 18 vocally health) were recorded: numbers 1-20 (42 syllables) + vowel/a/. Three different VSL were edited: VSL_long, 1-20 + 3 seconds vowel/a/; VSL_cust, customized length, were voiced-segments of the continuous speech had the same length of the vowel (mean = 18.73 syllables corresponding to 3 seconds of only-voiced segments) + 3 seconds vowel/a/; VSL_short, 1-10 (15 syllables) + 3 seconds vowel/a/. Three voice specialists perceptually judged the overall voice quality (G); 3 sessions were performed to evaluate each VSL variant. AVQI's precision and Spearman correlation were assessed. RESULTS: The intra-rater reliability was "almost perfect" (kappa >0.826) for all evaluators in VSL_short; "substantial" (0.684) and "almost perfect" (0.897) in VSL_cust and "fair" (0.447) to "almost perfect" (1.000) in VSL_long. The inter-rater reliability was "moderate" (0.554) for VSL_long, "substantial" (0.622 and 0.618) for VSL_cust and VSL_short. The Gmean and AVQI_mean were perceived as more severe for longer samples and less severe for shorter samples. Considering the AVQI, VSL_short (r = 0.665) presented the higher correlation. VSL_cust presented the best area under the ROC curve (0.821). VSL_long and VSL_cust specificity was 100%, VSL_short specificity was 75%; higher sensitivity was observed for VSL_short (74%). CONCLUSION: The voice quality outcomes changes for different VSLs. Longer VSLs seem to be perceived as more deviated, shorter VSLs seem to be more reliable and have better correlation with the acoustic analysis. The AVQI best accuracy was found at a customized length. Thus, to increase the voice analysis reliability, standardized procedure must be followed, including a precise speech material control allowing comparison among clinics and voice-centers.

RESUMO

PURPOSE: To evaluate the ability that in tune and out of tune individuals have to identify normal and deviated voice qualities and to compare it with their performance in auditory processing tests and perceptual judgment. METHOD: The study investigated 15 in tune and 15 out of tune individuals. Participants were matched for age and sex, were amateur choir singers, had normal hearing thresholds and normal vocal quality. All individuals underwent Pitch-matching scanning to be classified as in or out of tune. Next, they performed the Pitch Pattern Sequence (PPS) and the Duration Pattern Sequence (DPS) tests and the perceptual judgment of 36 voices plus 20% of repetition for reliability analysis. RESULTS: The out of tune individuals had worse performance in the PPS and DPS for both ears (p=0.002 RE; p=0.001 LE; p=0.009 DPS); no difference was observed in the perceptual judgment and the reliability (p=0.153). However, participants with normal PPS and DPS had better performance in the perceptual judgment and better reliability (p=0.033). Thus, individuals with disorders in temporal auditory processing skills have greater difficulty in the perceptual judgment and have lower intra-rater reliability, despite being in or out of tune. CONCLUSION: It can be observed that voice tone is not required to guarantee good perceptual judgment. However, temporal patterns and intra-rater reliability are essential to perceptually assess normal and altered voice qualities. Therefore, auditory training should be included in programs that aim to develop voice perceptual judgment abilities.

RESUMO

OBJECTIVES: To complete the validation and to study the psychometric properties of the Brazilian Portuguese version of the Vocal Fatigue Index (IFV). MATERIAL AND METHODS: This is a validation study of a diagnostic instrument utilizing a cross-sectional design and phases with quasi-experimental design. The total sample was composed of 212 participants, divided into two groups: Dysphonic Group and Vocally Healthy Group. All participants answered the VFI protocol. Data analysis consisted of the following steps: exploratory factor analysis, validity analysis, reliability analysis, sensitivity analysis, receiver operating characteristic, and area under the curve analysis. RESULTS: The Brazilian Portuguese version of the VFI called Índice de Fadiga Vocal-IFV, has 17 items and four factors. The IFV is a valid, reliable and sensible instrument to measure the self-perception of vocal fatigue. The threshold values for each factor was: 4.50 for tiredness and voice impairment; 3.50 for avoidance of voice use; 1.50 for physical discomfort and 8.50 for improvement of voice symptoms with rest. The threshold value for the total score was 11.50. CONCLUSION: The Brazilian Portuguese version of the VFI is a valid instrument to assess the self-perception of vocal fatigue, especially in dysphonic individuals.

RESUMO

PURPOSE: Verify the perception of popular and classical singers in relation to vocal symptoms and their possible relations regarding knowledge of health and vocal hygiene. METHOD: This study was composed of 242 singers, aged between 17 and 60, of both sexes. A total of 56 singers were selected, with 186 singers, divided into 104 Popular Singers Group (PSG) and 82 Classical Singers Group (CSG). All participants answered the questionnaire for identification and also vocal self-assessment, and two protocols were applied, namely: Brazilian validated version of Voice Symptom Scale - VoiSS (Escala de Sintomas Vocais - ESV) and Questionário de Saúde e Higiene Vocal (QSHV). RESULTS: The largest number of participants was female. The classical singers presented more time of singing class than the popular ones. Show hours of 1-2 hours was higher in the number of subjects responding to both groups of singers. Classical singers presented greater perception of vocal symptoms when compared to the popular ones for total and emotional scores of the Brazilian validated version of VoiSS. The popular and classical groups do not make any difference regarding health and vocal hygiene, even though the groups obtained values above the QSHV normality score. There was no correlation between knowledge about vocal health and hygiene and vocal symptoms in singers. CONCLUSION: Classical singers are more affected by vocal changes, especially women. The singers obtained a good degree of knowledge in vocal hygiene, not differing about the styles. The perception of vocal alteration in popular and classical singers seems to have no relation with the degree of health knowledge and vocal hygiene.

RESUMO

OBJECTIVE: To translate and cross-culturally adapt the Cough Severity Index to Brazilian Portuguese. MATERIAL AND METHODS: This is a study with observational, cross-sectional, and analytical design. The procedure for translation and cross-cultural adaptation followed the recommendations of the Scientific Advisory Committee of the Medical Outcomes Trust and was performed in five stages: translation, synthesis, back translation, committee review, and pretesting. The sample for the pretest consisted of 34 participants with refractory chronic cough, 11 males and 23 females, with an average age of 48 years and 1 month. RESULTS: The title of the questionnaire, the answer options, and seven of the ten questions were agreed upon by three judges, the remaining three questions were retranslated by a fourth judge. After back-translation and committee review, editing of question five was necessary. The option "never" was more frequently selected for four questions and the option "always" for six questions. There was a significantly higher proportion of other response categories of the instrument compared to the response category "not applicable." CONCLUSION: This study resulted in the elaboration of a translated and cross-culturally adapted version of the Cough Severity Index in Brazilian Portuguese.

RESUMO

OBJECTIVE: To compare vocal symptoms and self-regulatory behaviors between Chileans having behavioral dysphonia and those who were vocally healthy; and to correlate their vocal symptoms and self-regulatory behaviors. MATERIAL AND METHODS: The 100 Chileans who participated in this study were divided into the dysphonic group (DG) having behavioral dysphonia and the vocally healthy group (VHG). The DG and VHG each had 50 participants (32 females and 18 males), whose mean ages were 28.3 and 28.6 years, respectively. The participants responded to the Chilean Spanish versions of the Short Self-Regulation Questionnaire (SSRQ-Ch) and Voice Symptom Scale (VoiSS) instruments. The data were analyzed using descriptive and inferential statistics. RESULTS: The VHG Chileans had significantly lower scores in the VoiSS domains and significantly higher scores in the total and impulse control domains of SSRQ-Ch as compared to the DG Chileans. There was a negative correlation between all VoiSS domains as well as the total and impulse control domains of SSRQ-Ch. CONCLUSION: The DG Chileans had more vocal symptoms and less self-regulation of general behavior and impulse control than the VHG Chileans. There was an inverse relationship between the frequency of vocal symptoms and the self-regulated general and impulse control behaviors.

RESUMO

OBJECTIVE: This study aims to translate and cross-culturally adapt the throat scale of the Voice Handicap Index to the Brazilian Portuguese language.uracy. MATERIAL AND METHODS: This was performed in five phases translation, synthesis, back translation, review, and pretest. Fifty subjects participated in the pretest, of which 22 participants had chronic cough, 13 had laryngopharyngeal reflux, and 15 had behavioral dysphonia. Of the 50 participants, 40 were female and 10 male, with an average age of 44 years and six months. RESULTS: In the translation process, only question four had to be translated by a fourth judge. After the back-translation and committee review steps, it was necessary to make adjustments to questions one, four, five, seven, eight, nine, and 10. With regard to question five, the "never" option was significantly associated with the clinical group with behavioral dysphonia (P = 0.016), and with regard to question eight, the option was occasionally significantly associated with the clinical group with laryngopharyngeal reflux (P = 0.015). For question six, all the response categories of the questionnaire, had a significantly higher proportion compared to "not applicable" (P < 0.001). For the other questions, no participants selected the "not applicable" option. CONCLUSION: The translation and cross-cultural adaptation of the throat scale of the Voice Handicap Index to Brazilian Portuguese was performed successfully; the Voice Handicap Index in Brazilian Portuguese prepared herein was called the Índice de Desvantagem Vocal-Garganta.

RESUMO

OBJECTIVES: To elaborate reduced versions of the Pediatric Vocal Symptoms Questionnaire (PVSQ) protocol for the two forms of application of the instrument: self-evaluation (SE) and parental evaluation (PE). METHODS: The Brazilian validation database of the PVSQ was used (Zip code: 758,309). Data were collected from 716 people, comprising 367 children and adolescents and 349 parents/guardians with and without voice complaint and/or vocal alteration. Three major procedures were adopted: 1. Verification of suitability of the database; 2. Determination of the extraction technique and the number of factors to be extracted, and 3. Decision on the type of factor rotation. For factor analysis, the Kaiser rule and Varimax rotation were used; Spearman's correlation analysis was used to verify the degree of relationship between the PVSQ variables, both of the SE and PE. The Mann-Whitney test was used to analyze the ROC curve of the general score of vocal symptoms of each version. A 5% significance statistical level was adopted. RESULTS: Factor analysis made it possible to elaborate four new versions of the PVSQ, called: "common core of the PVSQ" (SE and PE), "common core of the PVSQ reduced version" (SE and PE), "PVSQ SE reduced version" and "PVSQ PE reduced version". The most complete version of the PVSQ has 7 domains in the SE and 5 in the PE. The common core of the PVSQ SE reduced version had a better area under the ROC curve (AUC), efficiency and sensitivity, and the PVSQ PE reduced version had better specificity. CONCLUSIONS: Four new reduced PVSQ versions are available, containing 10 to 26 items. Aspects of specificity, efficiency and sensitivity, as well as discriminating capacity should be considered in the choice of the version and is a prerogative of the clinician who applies the instrument. As the questionnaire allows the comparison between the parental evaluation and the self-evaluation, it is recommended to apply the same version for parents and children.
