“…The high prevalence of childhood dysphonia mandates that special attention be paid to the evaluation and diagnosis of children's voices, with objective measures to enable an understanding of the severity of the voice deviance and how it manifests itself at different stages between the ages of 3 and 9 years 1,[19][20][21] .…”

Resumo:OBJETIVO:analisar o poder discriminatório do diagrama de desvio fonatório na avaliação do tipo de voz predominante e da intensidade do desvio vocal em crianças.MÉTODOS:coletou-se a vogal /ε/ sustentada de 93 crianças. A intensidade do desvio e a qualidade vocal foram analisadas por meio da escala analógico-visual. Utilizou-se o diagrama para a análise acústica, com avaliação da distribuição dos sinais vocais de acordo com a área, quadrante, forma e densidade. Realizou-se o teste de igualdade de proporções e o teste Qui-quadrado(x2) para comparar as variáveis, e o teste de Correlação de Spearman para correlacionar as medidas acústicas e perceptivo-auditivas.RESULTADOS: houve correlação entre a classificação de quadrantes e a intensidade do desvio vocal para todos os parâmetros analisados. Houve diferença estatisticamente significante entre a proporção de crianças com rugosidade, soprosidade, tensão e instabilidade em relação à área, ao quadrante e à forma. Não houve diferença estatisticamente significante entre a proporção de crianças com e sem desvio da qualidade vocal em relação a todos os parâmetros analisados, ao considerar a distribuição das vozes nos quadrantes.CONCLUSÃO: o diagrama de desvio fonatório foi capaz de diferenciar a qualidade vocal predominante por meio da distribuição nos quadrantes, embora não tenha discriminado as vozes infantis saudáveis e alteradas.

“…Some studies [6,17,18] have shown a decrease in F₀ standard throughout development, explained by an increase in vocal fold length and mass, expansion and development of the vocal tract, and the approximation of male and female voice-related adult models.…”

“…A recent study [6] demonstrated that there is no typical F₀ for each age range and that there is no correct age for changes to occur, but that there are periods of mild changes for both boys and girls, starting between 11 and 12 years of age. In the present study, there were significant changes after 5 years, corresponding to the end of early childhood, although we have not studied older children to determine whether there are also significant changes in early adolescence.…”

“…Although the importance of characterizing the pediatric voice with subjective and objective data is widely recognized (as this would lead to better identification of vocal deviation and monitoring of the progression of vocal therapy), there are few publications with normal-range data for voice in childhood [6]. …”

Objective: To analyze perceptual-auditory and acoustic characteristics of children's voices of different age ranges. Patients and Methods: Ninety-three 3- to 10-year-old children grouped from 3 to 5, 6 to 7, and 8 to 10 years served as participants. The severity of vocal deviation and the parameters of roughness, breathiness, strain, and instability were assessed using a visual analog scale. We calculated the mean and standard deviation of fundamental frequency (F₀), jitter, shimmer, and glottal-to-noise excitation ratio for the sustained vowel, and the mean of F₀ variability for connected speech. Results: The most affected voices were in the age range 8-10 years, and only the phonation tension level was reduced as a result of aging. There were significant differences between children aged 3-5 years and the other age ranges for F₀ mean for sustained vowels and F₀ variability. Conclusion: Children aged 8-10 years had the highest severity of vocal deviation. There was a significant reduction of phonation tension and measure of F₀, jitter, and shimmer after the age of 5 years.

Sustained vowel utterance and continuous speech samples provide consistent measures of fundamental frequency. Frequency-based analysis of sustained vowel recordings improves the reliability of perturbation measures. Continuous speech recordings can be obtained in children and demonstrate good to excellent reliability across recordings. This suggests that frequency-based analysis of continuous speech may be more representative of a child's voice and therefore may be of use in the study both of the developmental changes of the pediatric voice as well as the study of vocal changes pretreatment and posttreatment in children with voice disorders.
