Voz, monotonia e autonomia no ambiente de trabalho de professores / Voice, monotony, and autonomy in teachers' work setting / Voz, monotonía y autonomía en el entorno laboral docente

Introdução: a relação entre voz e trabalho é objeto de estudo constante. Ainda não há investigação sobre a relação de monotonia e autonomia com queixas vocais. Objetivo: investigar a relação entre a monotonia e a autonomia no ambiente de trabalho com o surgimento de queixas vocais entre professores. Método: estudo exploratório, qualitativo e descritivo, realizado a partir de grupo focal considerando o ineditismo da temática do estudo. Dez professores triados em estudo anterior com suspeita de distúrbio de voz pelo Índice de Triagem de Distúrbio de Voz, que indicaram percepção de monotonia e falta de autonomia no ambiente de trabalho por meio do instrumento Condições de Produção Vocal de Professores foram convidados a participar. Sete professores aceitaram e foram conduzidos dois grupos focais. Perguntas disparadoras sobre monotonia e autonomia no ambiente de trabalho foram feitas. Após análise de conteúdo, foram criadas quatro categorias principais e subcategorias de análise. Resultados: os participantes debateram questões relacionadas à quebra de expectativas sobre o trabalho, frustrações, rotina e desafios diários. Considerações sobre a voz estavam relacionadas ao uso repetitivo e por longos períodos e ambiente com acústica desfavorável. Queixas como rouquidão e baixa projeção vocal foram citadas. Conclusão: monotonia no ambiente de trabalho foi percebida como algo repetitivo e as relações com o surgimento de queixas vocais podem estar relacionadas a situações de uso da voz de forma intensa e constante. A falta de autonomia parece ocasionar a monotonia e, consequentemente, desmotivação, frustração com a carreira e adoecimento, dentre eles, o distúrbio de voz. (AU)

Introduction: the relationship between voice and work is the subject of constant study. There is still no investigation into the relationship between monotony and autonomy and vocal complaints. Objective:to investigate the relationship between monotony and autonomy in the workplace with the emergence of vocal complaints among teachers. Method: exploratory, qualitative and descriptive study, carried out through a focus group considering the novelty of the study theme. Ten teachers screened in a previous study with suspected voice disorders using the Voice Disorder Screening Index, who indicated a perception of monotony and lack of autonomy in the work environment using the Teacher Vocal Production Conditions instrument were invited to participate. Seven teachers accepted and two focus groups were conducted. Triggering questions about monotony and autonomy in the workplace were asked. After content analysis, four main categories and subcategories of analysis were created. Results: participants discussed issues related to broken expectations about work, frustrations, routine and daily challenges. Considerations about the voice were related to repetitive use for long periods and an environment with unfavorable acoustics. Complaints such as hoarseness and low vocal projection were cited. Conclusion: monotony in the work environment was perceived as something repetitive and the relationship with the emergence of vocal complaints may be related to situations of intense and constant use of the voice. The lack of autonomy seems to cause monotony and, consequently, demotivation, frustration with one's career and illness, including voice disorders. (AU)

Introducción: la relación entre voz y trabajo es objeto de constante estudio. Todavía no se ha investigado la relación entre monotonía, autonomía y quejas vocales. Objetivo: investigar la relación entre monotonía y autonomía en el lugar de trabajo con la aparición de quejas vocales entre docentes. Método: estudio exploratorio, cualitativo y descriptivo, realizado a través de un grupo focal considerando la novedad del tema de estudio. Se invitó a participar a diez docentes evaluados en un estudio previo con sospecha de trastornos de la voz mediante el Voice Disorder Screening Index, que indicaron una percepción de monotonía y falta de autonomía en el ambiente de trabajo utilizando el instrumento Teacher Vocal Production Conditions. Siete profesores aceptaron y se realizaron dos grupos focales. Se formularon preguntas desencadenantes sobre la monotonía y la autonomía en el lugar de trabajo. Luego del análisis de contenido, se crearon cuatro categorías y subcategorías principales de análisis. Resultados:los participantes discutieron cuestiones relacionadas con expectativas rotas sobre el trabajo, frustraciones, rutina y desafíos diarios. Las consideraciones sobre la voz estuvieron relacionadas con el uso repetitivo por períodos prolongados y un ambiente con acústica desfavorable. Se citaron quejas como ronquera y baja proyección vocal. Conclusión: la monotonía en el ambiente laboral fue percibida como algo repetitivo y la relación con la aparición de quejas vocales puede estar relacionada con situaciones de uso intenso y constante de la voz. La falta de autonomía parece provocar monotonía y, en consecuencia, desmotivación, frustración con la propia carrera y enfermedades, incluidos trastornos de la voz. (AU)

Estudantes de fonoaudiologia: autoavaliação da voz, sintomas vocais e diagrama de desvio fonatório / Speech pathologist students: voice self-assessment, vocal symptoms and phonatory deviation diagram / Estudiantes de fonoaudiología: autoevaluación de la voz, síntomas vocales y diagrama de desviación fonatoria

Introdução: considera-se importante que fonoaudiólogos apresentem suas vozes como modelo ao realizar uma intervenção fonoaudiológica. Objetivo: conhecer a autoavaliação da voz e sintomas vocais de um grupo de acadêmicos de fonoaudiologia relacionando os achados ao diagrama de desvio fonatório. Método: estudo do tipo analítico, observacional, com 88 estudantes de Fonoaudiologia de uma mesma faculdade, 82 mulheres e seis homens, média de idade de 21,9 anos, sem diagnóstico de disfonia, autorreferidos saudáveis. Foram registrados e comparados dados relativos à autoavaliação da voz e de sintomas vocais, utilizando-se a Escala de Sintomas Vocais. Numa segunda etapa os estudantes foram convidados a realizar uma análise acústica de suas vozes e os que aceitaram (63,6%) procederam com a coleta das amostras de voz, programa VoxMetria® ­ CTS. Para tratamento dos dados foram utilizados Teste T ­ student e Matriz de Correlações construída com os resultados do Teste T- student (nível de confiança de 95%, alpha 5%). Resultados: a Escala de Sintomas Vocais revelou 44,31% dos participantes com escores brutos igual ou superior a 16 pontos, indicando risco vocal, com maior comprometimento do domínio físico. Alunos do último ano obtiveram escores mais elevados, com predomínio de secreção e pigarro na garganta. Houve correlação positiva entre fumar (7,95%) e aumento da nota final. A análise acústica revelou 40% das vozes com diagrama de desvio fonatório fora do quadrante de vozes normais, irregularidade da voz, jitter e shimmer alterados. Conclusão: a combinação dos dois instrumentos utilizados para conhecimento de risco de disfonia em estudantes de Fonoaudiologia mostra-se relevante e reforça a importância de programas de prevenção de saúde vocal também em futuros fonoaudiólogos.

Introduction: speech therapists must present their voices as a model for a speech therapy intervention. Objective: to understand the voice self-assessment and vocal symptoms of a group of speech therapy students, relating the findings to the phonatory deviation diagram. Method: an analytical observational study was conducted with 88 speech therapy students from the same college, consisting of 82 women and 6 men, averaging 21.9 years old, who reported no diagnosis of dysphonia, and self-reported as healthy. Data relating to voice self-assessment and vocal symptoms were recorded and compared, using the Vocal Symptoms Scale (VoiSS). In the second stage, students were invited to perform an acoustic analysis of their voices and those who accepted (63.6%) proceeded with the collection of voice samples, using the VoxMetria® ­ CTS program. To process the data, the T-student Test and Correlation Matrix constructed with the results of the T-student Test (confidence level of 95%, alpha 5%) were used. Results: The Vocal Symptoms Scale (student T-test) revealed 44.31% of participants with raw scores equal to or greater than 16 points, indicating vocal risk and greater impairment of the physical domain. Final year students obtained higher scores, with a predominance of secretion and throat clearing. There was a positive correlation between smoking (7.95%) and an increase in the final grade. The acoustic analysis revealed 40% of the voices with a phonatory deviation diagram outside the quadrant of normal voices, voice irregularity, altered jitter, and shimmer. Conclusion: The combination of the two instruments used to understand the risk of dysphonia in speech therapy students is relevant and reinforces the importance of vocal health prevention programs for future speech therapists.

Voice Disorder, Job Stress, and COVID-19 in Teachers: Impacts in Times of Pandemic

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

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

Vocal Approach to Transgender Individuals: The Journey Taken in Chile and Argentina

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

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

Adaptación y validación del Voice Handicap Index y su versión abreviada al español rioplatense de Argentina

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

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

Behind the Headset: Predictive Accuracy of Patient-Reported Outcome Measures for Voice Symptoms in Call Centers

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

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

Surveying Colombian Speech-Language Pathologists on their Reported Training & Practices of Auditory-Perceptual Evaluation of Voice

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

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

Vocal Load of University Professors: Preliminary Results

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

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

Presentation of the ATLETAS DA VOZ™ Conditioning Program

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

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

Outcomes of a Community of Practice on Quebec Speech Language Pathologists' Voice Assessment Practices and Professional Identity

In a context where different protocols for recommended practices in clinical voice assessment exist, while there are gaps in the literature regarding the evidence base supporting assessment procedures and measures, clinicians from regions where a strong community holding expertise in clinical and scientific voice practices lack can struggle to confidently develop their voice assessment practices. In an effort to improve voice assessment practices and strengthen professional identity among speech-language pathologists in Quebec, Canada, a community of practice (CoP) was established, with the aim of promoting knowledge sharing, implementing change in clinical practice, and improving professional identity. Thirty-nine participants took part in the CoP activities conducted over a four-month period, including virtual meetings and in-person workshops. Participants had a high rate of attendance (> 74% participation rate in virtual meetings), and were highly satisfied with their participation and intended to remain involved after the project's end. Statistically significant changes in voice assessment practices were observed post-CoP, regarding probability of performing assessments (p < .001), and perceived importance of assessment for evaluative purposes (p <.001), as well as improvements in assessment specific confidence, specifically for procedure of auditory-perceptual assessment (p < .001) and purpose of aerodynamic assessment (p = .05). Moreover, there was an increase in professional identity post-CoP (p < .001) and participants felt they made significant learnings. The present study highlighted the need to involve SLPs in future research to identify assessments that are relevant to the specific evaluative objectives of SLPs working with voice, and suggests CoPs are an efficient tool for that purpose.

En un contexto en el que existen diferentes protocolos para las prácticas recomendadas en la evaluación vocal clínica, y en el que se presentan vacíos en la literatura respecto a la base de evidencia que respalda los procedimientos y medidas de evaluación, los profesionales de regiones donde no hay una comunidad sólida con experiencia en prácticas vocales clínicas y científicas pueden enfrentar dificultades para desarrollar con confianza sus prácticas de evaluación vocal. Con el propósito de mejorar las prácticas de evaluación vocal y fortalecer la identidad profesional entre los logopedas de Quebec, Canadá, se estableció una comunidad de práctica (CdP). Esta tenía como objetivo fomentar el intercambio de conocimientos, implementar cambios en la práctica clínica y mejorar la identidad profesional. Un total de treinta y nueve participantes se involucraron en las actividades de la CdP, llevadas a cabo durante un período de cuatro meses, que incluyeron reuniones virtuales y talleres presenciales. Los participantes tuvieron una alta tasa de asistencia (> 74% de participación en las reuniones virtuales) y expresaron un alto grado de satisfacción con su participación, manifestando su intención de continuar involucrados después de la finalización del proyecto. Se observaron cambios estadísticamente significativos en las prácticas de evaluación vocal posterior a la CdP, en lo que respecta a la probabilidad de llevar a cabo evaluaciones (p < .001) y la percepción de la importancia de la evaluación con fines evaluativos (p < .001), así como mejoras en la confianza específica en la evaluación, particularmente en el procedimiento de evaluación auditivo-perceptual (p < .001) y el propósito de la evaluación aerodinámica (p = .05). Además, se registró un aumento en la identidad profesional posterior a la CdP (p < .001) y los participantes sintieron que obtuvieron aprendizajes significativos. El presente estudio destacó la necesidad de involucrar a los logopedas en investigaciones futuras, para identificar evaluaciones pertinentes a los objetivos evaluativos específicos de los logopedas que trabajan con la voz, y sugiere que las CdP son una herramienta eficiente con ese propósito.

Relação entre meditação, regulação emocional e expressão vocal: estudo de intervenção / Relación entre meditación, regulación emocional y expresión vocal: estudio de intervención / The relationship between meditation, emotional regulation and vocal expression: interventional study

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

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

Effect of recorded mother's voice on emergence delirium in pediatric patients: a systematic review with meta-analysis

Abstract Objective: Emergence delirium is a common complication in children. Recorded mother's voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother's voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother's voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger's voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger's voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother's voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

Correlation of acoustic voice analysis and Voice Handicap Index in patients with postoperative unilateral vocal cord paralysis after thyroid surgery

Unilateral vocal cord paralysis is frequently observed in patients who undergo thyroid surgery. This study explored the correlation between acoustic voice analysis (objective measure) and Voice Handicap Index (VHI, a self-assessment tool). One hundred and forty patients who had thyroid surgery with or without postoperative unilateral vocal cord paralysis (PVCP and NPVCP) were included. The patients were evaluated by the VHI and Dysphonia Severity Index (DSI) tools. VHI scores were significantly higher in PVCP patients than in NPVCP patients. Jitter (%) and shimmer (%) were significantly increased, whereas DSI was significantly decreased in PVCP patients. Receiver operating characteristics curve revealed that VHI scores were associated with the diagnosis of PVCP, of which VHI total score yielded an area under the curve (AUC) of 0.81. Among acoustic parameters, DSI was highly associated to PVCP (AUC=0.82, 95%CI=0.75 to 0.89). Moreover, we found a correlation between VHI scores and voice acoustic parameters. Among them, DSI had a moderate correlation with functional and VHI scores, as suggested by an R value of 0.41 and 0.49, respectively. VHI scores and acoustic parameters were associated with the diagnosis of PVCP.

A Study on the Influence of the Type of Finals on the Onset Time of the Stop Voice of Hearing Impaired Children / 听力学及言语疾病杂志

Objective To investigate the effect of final vowel types on the voice onset time(VOT)of differ-ent stops in children with hearing impairment,and to provide a basis for the acquisition and correction of stop sounds.Methods A total of 22 hearing-impaired children aged 3～6 and 22 children with normal hearing were ran-domly selected-18 consonant-vowel(CV)syllables composed of 6 stops and 3 single finals were recorded,using first tone.Using Praat 6.1.29 software to analyze and extract the stops VOT.Two-way ANOVA was used for each stop,the dependent variable was VOT,and the independent variables were hearing status and final type.Results Children in the hearing-impaired group had articulation errors in/t/,/g/,and/k/.Hearing status had significant effect on the main effect of plosives/g/,/p/,/t/,/k/(P＜0.05),and the VOT of slurs/g/,/p/,/t/,/k/in the normal hearing group significantly greater than the hearing-impaired group(P＜0.05).The main effect of finals on the VOT of the stops/b/,/p/and/t/was significant(P＜0.05).Hearing status and final type had an interac-tive effect on the stop/t/,and the simple main effect showed that the difference in VOT of/ti/between the hear-ing-impaired group and the normal hearing group was greater than that of/ta/and/tu/.Conclusion The stops/g/,/p//t/,/k/VOT of hearing-impaired children are smaller than those of with normal hearing.The difference in VOT of/ti/sound between the hearing impaired group and the normal hearing group is greater than that of/ta/sound and/tu/sound.In the teaching of the initial/t/sound for hearing-impaired children,we can start with/ta/and/tu/with less difference,and the/ti/sound is consolidated later.Pay attention to breathing and oral exercise training,to lay a good foundation for clear pronunciation.

A realist review of effective university-based wellness programs on physical activity, occupational balance, and vocal health

Background@#Wellness programs can be implemented in a university setting and may include varied elements such as physical activity, occupational balance, and vocal health. However, there is limited information that highlights and synthesizes why and how these programs work. Therefore, this study aimed to understand effective programs on physical activity, occupational balance, and vocal health for university constituents in relation to the implementation contexts, mechanisms, and outcomes (CMO).@*Methodology@#Guided by the Health Belief Model in the context of a realist review design, the researchers conducted an iterative search among seven peer-reviewed electronic databases in the health and education fields using a predetermined set of eligibility criteria. @*Results@#The search identified 6564 records, of which programs from 20 records contributed to data synthesis. Nine CMO statements were created, with physical activity programs accounting for most configurations. Key themes identified were tailored and individualized interventions, medium-term incentivization, lifestyle education programs utilizing information and communications technology, interdisciplinary multi-component programs, use of self-monitoring strategies, social support, and shared experiences among employees and students. Analysis of the mechanisms of these effective university programs revealed processes and structures that were consistent with elements of the Health Belief Model.@*Conclusion@#Effective university-based PA programs result from a health-supporting culture among staff and students, utilizing self-based, technological, and social approaches that target and address individual and organizational behaviors in physical activity, occupational balance, and vocal health. This realist review provides practical information that may guide the development of university-based programs and policies targeting these areas of wellness.
