[PMID: 37838586 DOI: 10.1016/j.jvoice.2023.08.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 08/22/2023] [Accepted: 08/22/2023] [Indexed: 10/16/2023]
Abstract
OBJECTIVE Verify the results from intensive short-term vocal therapy using the Finger Kazoo technique about the spectrographic vocal measurements of teachers. METHODS Controlled and randomized trial. Spectrographic vocal assessment was performed by judges before and after intensive short-term vocal therapy with Finger Kazoo. Sample was composed of 41 female teachers. There were two study groups (with vocal nodules and without structural affection of the vocal folds) and the respective control groups. For the statistical analysis of the data, nonparametric tests were used (Mann-Whitney test and Wilcoxon test). RESULTS After intensive short-term vocal therapy with Finger Kazoo, improvement in voice spectral parameters, such as improvement in tracing (color intensity and regularity), greater definition of formants and harmonics, increased replacement of harmonics by noise, and a greater number of harmonics, mainly in the group without structural affection of the vocal folds. CONCLUSION There was an improvement in the spectrographic vocal parameters, showing greater stability, quality, and projection of the emission, especially in female teachers without structural affection of the vocal folds.

Abstract
PURPOSE to identify a set of requirements for the development of an auditory-perceptual training simulator (APT) based on the experience of professors who provide APT. METHODS This is a cross-sectional, descriptive study with a quantitative approach. Twenty-two professors answered an online questionnaire containing 31 items related to APT, involving items about the professional profile, conditions for APT in undergraduate and postgraduate courses in Speech Therapy, APT structure, and evaluation of the APT effect. RESULT it was observed that there is a variation in APT procedures performed in Brazil. The main requirements indicated by the respondents for the APT involve the use of synthesized voices in the initial moments, followed by human voices later; the use of speech tasks with sustained vowels and connected speech; the insertion of complementary information such as gender, age, the profession of the speaker and the spectrography of the vocal signal; training with a minimum time of six hours; the evaluation of the training effect by comparing intra- and inter-judge agreement before and after training; the addition of the parameters of general degree of vocal deviation, roughness, breathiness, and strain; the use of validated continuous and numerical scales; and offering it from the second year of the undergraduate program. CONCLUSION although there is variability in the response of experts, a minimum set of requirements indicated for performing APT with new judges was identified.

Abstract
PURPOSE To present the translation into Brazilian Portuguese and cross-cultural adaptation of the Apraxia of Speech Rating Scale (ASRS) version 3.5. METHODS Validation study restricted to translation and cross-cultural adaptation. The following steps were carried out: translation and synthesis of translations; verification of applicability of the scale synthesis by judges recruited for this purpose; analysis of the relevance and feasibility of the scale calculated by the Content Validity Index (CVI), individual (CVI-I) and total (CVI-T). Eighteen speech therapists were selected. Their answers were used for the analysis of agreement (intraclass correlation coefficients - ICC) and for the calculation of the Content Validity Index (CVI). Finally, the synthesis of the translation was matched in terms of semantic, idiomatic, experiential, conceptual, syntactic, grammatical, and operational equivalence. RESULTS The ICC ranged between 0.83 and 0.94. Six items obtained values higher than 0.9. The other items presented values between 0.8 and 0.9. The CVI-I and CVI-T had excellent values (CVI ≥ 0.78) for relevance and feasibility. CONCLUSION The Brazilian version of the ASRS 3.5 presents semantic, idiomatic, experiential, conceptual, and syntactic/grammatical equivalence to the original document. Thus, it is ready for the next validation steps.

Abstract
During the XXVIII Brazilian Congress of SBFa, 24 specialists met and, from a leading position on scientific research as a tool for connecting laboratory and clinic, five fronts of knowledge of the voice specialty were discussed as following: Perceptual-auditory judgment of vocal quality; 2. Acoustic analysis of the vocal signal; 3. Voice self-assessment; 4. Traditional techniques of therapy; 5. Modern techniques of electrostimulation and photobiomodulation (PBMT) in voice. Part "a" of this publication was associated with the consolidation of the analyses of the first three aspects. The trend in the perceptual-auditory judgment of vocal quality was related to the use of standard protocols. The acoustic evaluation of the vocal signal is accessible and can be done descriptively or by extraction of parameters, thus preferring multiparametric measures. Finally, the analysis of the individual himself closes this triad of voice documentation, which will be the basis for the conclusion of the evaluation, reference for monitoring progress, and evaluation of treatment results.

Abstract
INTRODUCTION Children with speech sound disorders (SSDs) who present the devoicing of plosive and/or fricative sounds may have difficulties with glottal respiratory control. OBJECTIVE To analyze acoustic vocal measures, spectrographic aspects and the risk of dysphonia among children with devoicing SDDs and compare the results with those of other groups of children. METHODS Twenty-five boys aged between six and 12 years participated. They were divided into four groups: the SSD-devoicing (PPDG), dysphonia (DG), SSDs other than devoicing (PPOG) and control groups (CG). The vocal tasks were recorded, and perceptual-auditory and acoustic voice analyses were performed. The children's parents answered questions about voice-related aspects (to determine a dysphonia risk score). All data were compared among the groups. RESULTS Due to the sample size, an effect size analysis was considered, and the results showed possible differences between the PPDG and the other groups in measures of fundamental frequency (F0), jitter, shimmer, harmonic-to-noise ratio, maximum frequency of harmonic definition and dysphonia risk score. CONCLUSIONS The PPDG showed a high F0 and abnormal jitter and shimmer values. Although the voices of the children in this group had more harmonics than noise, the maximum frequency for defining the harmonics was very restricted. The PPDG had the lowest dysphonia risk score among all of the groups. Variations in F0, jitter and shimmer may indicate difficulties with controlling vocal adjustments, which appear to be hyperfunctional and not to impact vocal projection or voicing.

Zenari MS, Cota ADR, Rodrigues DDA, Nemr K. Do Professionals Who Use the Voice in a Journalistic Context Benefit from Humming as a Semi-occluded Vocal Tract Exercise? J Voice 2021:S0892-1997(21)00100-4. [PMID: 33895007 DOI: 10.1016/j.jvoice.2021.03.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 03/05/2021] [Accepted: 03/12/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION Many vocal enhancement and rehabilitation programs for voice professionals define vocal exercises without analyzing their effects on that specific population in which they will be applied, in the established dose and often without considering the presence and absence of vocal alteration. Journalists have sought the voice clinic due to new professional vocal demands and a vocal program is being elaborated. OBJECTIVE To determine the immediate effect of humming in professionals with and without voice disorders who work under high vocal demand in a journalistic context. METHOD Thirty-six individuals who completed the Dysphonia Risk Screening Protocol and underwent voice recording participated in the study. Three speech therapists defined the presence and/or absence of vocal changes by consensus. Subsequently, five repetitions of humming were proposed; the exercises lasted five seconds each and were separated by five seconds of complete silence, and recordings were made before and after the exercise (vowel and phrase). For the pre and post comparison between the groups with and without vocal changes, acoustic measurements and spectrogram, including the classification of the signal type, were performed. RESULTS The sample had a similar distribution of men and women and a mean age of 39.9 years. Most of the professionals were journalists or reporters. The risk of dysphonia was high for half of the sample, and the presence of vocal changes, predominantly mild ones, was identified in 56%. After the exercise, a decrease in noise at low frequencies and an improvement in the series of harmonics and the signal type were observed in both groups; a decrease in irregularity was observed only in the participants without vocal changes. CONCLUSION The proposed humming exercise had an immediate positive effect on the voice of professionals working in a journalistic context, and the changes were particularly evident in aspects of the voice that were initially altered.

Abstract
OBJECTIVE in order to contribute of the collective actions of the teacher's vocal health, the specific goal was to build a guide gathering the appliable didactic content in these actions. That being, the stages performed in the instrument elaboration of the denominated Teachers' Vocal Health Guide (TVHG) will be presented. MATERIAL AND METHODS The elaboration process of the guide is composed of three stages: (1) parameter selection to compose the guide based on a literature review; (2) submission to a specialist examining board, with the calculation of the Content Validity Index (CVI) and the Kappa agreement coefficient; (3) content validation - the instrument was submitted to an analysis of a judges committee, and from the results the Cronbach Alfa coefficient and the CVI were calculated. RESULTS The elaboration of the TVHG underwent three stages. In the first stage, called parameter selection, 20 didactic contents were found, consisting of 14 theoretical and six practices. In the second stage, an evaluation of the guide was performed by a specialist examining board and two contents were excluded since their CVI was below 8. The result of the Kappa Coefficient Calculation was 0.281. In the third stage, the TVHG underwent evaluation of a new group denominated judges committee, and the items were punctuated as very relevant and completely relevant. The result of the Cronbach Alfa coefficient for the instrument with 18 items was 0.721, and this value categorizes the instrument as valid. It is necessary to continue the process of instrument validation, possibly investigating the applicability of TVHG in the teachers' opinion. CONCLUSION The current study presents the TVHG from the description of the three stages performed to elaborate a systematized instrument denominated TVHG, which suggests a gathering of didactic content that are appliable in collective actions of vocal health with this professional category.

Abstract
OBJECTIVE To verify the validity in the internal consistency in the spectrographic analysis protocol (SAP). MATERIAL AND METHODS Thirty-nine students of the Speech-Language Pathology graduate program and 38 speech-language pathologists, specialized in voice, participated in the study. The participants made visual inspections of 10 spectrograms and marked the items of the SAP. For analysis of the internal consistency in the SAP, the exploratory factor analysis (EFA) and confirmatory factor analysis were performed. RESULTS Most items showed corrected item-total correlation above 0.3, indicating that the items have a good relationship with each other and with the SAP as a whole. Six items presented values below the average, suggesting the exclusion of these from the construct. However, three of these were maintained because they were judged as important parameters in clinical practice, requiring the training of judges when using the SAP to properly understand the items. The EFA regrouped the previous domains of the SAP into three factors. All items presented a factor load above 0.4, suggesting the retention of all, except for the items previously indicated, for exclusion. The confirmatory factor analysis corroborated with the EFA and its indexes. CONCLUSION The SAP has good internal consistency. All items have a good degree of relationship with each other and contribute positively to the protocol as a whole. The final version of the SAP, at this stage, has 15 items (from the 25 items of the initial SAP version), distributed among three domains.

Abstract
OBJECTIVE To present evidence of the reliability and validity in the Spectrographic Vocal Assessment Protocol. METHODS The sample consisted of 50 female participants, aged 25-62 years old, 24 with a otorhinolaryngological diagnosis of the normal larynx or posterior glottal gap, and 26 diagnosed with vocal fold disturbances. The emission of the vowel /a:/ was analyzed by the Real Time Spectrogram software. The spectrographs were analyzed with a protocol by two speech therapist judges. For reliability analysis, inter- and intrajudge analysis were performed using the Kendall coefficient. For criterion validity, the t test for matched samples with Bonferroni correction was used to compare the average performance of the protocol between the two groups of subjects. RESULTS Protocol reliability: for broadband items, the agreement between judges ranged from moderate (0.462) to almost perfect (0.888), and it is significant for all items, and an intrajudge agreement was almost perfect and significant (0.865-1.000) for all items. For narrowband items, the agreement between judges ranged from moderate (0.469) to almost perfect (0.922), and it is significant for all items except for the presence of "subharmonics in high frequencies" where agreement was moderate (0.504), but not significant, and the intrajudge agreement was almost perfect (0.874-1.000) and significant for all items. Criterion validity: for most broadband and narrowband items, the groups with normal or altered diagnosis differed statistically. CONCLUSION The Spectrographic Vocal Assessment Protocol presented adequate evidence in reliability and validity.

Abstract
OBJECTIVE To develop and seek evidence of content validity of a spectrographic vocal assessment protocol. METHODS Methodological study for development and validation of an assessment instrument. A broad literature search was conducted to develop and substantiate a spectrographic vocal assessment protocol. The protocol items were sent to five expert judges, speech therapists, nonauthors of the research, doctors, and clinicians, with experience in the field of voice and spectrographic acoustic analysis, who individually analyzed the protocol items. For data analysis, the Gwet analysis and the Content Validity Ratio formula were used. RESULTS The Spectrographic Vocal Assessment Protocol was developed, subdivided into Broadband and Narrowband. Twenty-four protocol items had Content Validity Ratio 1.0 and 25 items had 0.6. Gwet analysis indicated substantial agreement (0.656) for broadband and almost perfect (0.848) for narrowband items. CONCLUSION Evidence of satisfactory content validity was obtained in the development of the protocol.

Abstract
RESUMO Objetivo Verificar se existe associação entre a presença de alteração laríngea, a análise perceptivo-auditiva da qualidade vocal e a classificação espectrográfica do sinal vocal em indivíduos com distúrbio de voz. Métodos Participaram 478 pacientes com distúrbios de voz. Foi realizada gravação da vogal /Ɛ/ sustentada e o exame médico para estabelecimento de diagnóstico laríngeo. Os espectrogramas da vogal foram utilizados para classificação dos sinais em Tipo I, II, III e IV. Resultados Vozes de indivíduos sem alteração laríngea foram classificadas, predominantemente, como Tipo I e Tipo II, enquanto sinais de indivíduos com alteração laríngea foram classificados nos Tipos III e IV. Vozes desviadas foram classificadas, predominantemente, como Tipo II, enquanto os sinais de pacientes com desvio vocal foram categorizados, predominantemente, como Tipos II e III. Apenas os sinais de indivíduos com desvio vocal foram classificados como Tipo IV. Sinais Tipo III e IV apresentaram valores mais elevados no grau geral do desvio e nos graus de rugosidade e soprosidade, em relação aos sinais Tipo I e Tipo II. Os sinais Tipo IV apresentaram maior grau geral e graus de rugosidade e soprosidade, em comparação aos sinais Tipo III. Apenas os sinais Tipo IV apresentaram valores mais elevados no grau de tensão, em relação aos sinais Tipo I, II e III. Conclusão Há associação entre a presença de alteração laríngea, a análise perceptivo-auditiva e a classificação espectrográfica do sinal vocal em indivíduos com distúrbio de voz.
