“…Results show that all patients had a decrease in the mean, maximum, and minimum fundamental frequency values, characterizing lower emissions. This result is correlated to the auditory-perceptual analysis in this study, with presence of lower pitch, which agrees with literature results (7)(8)(9)(10) . A study with ten teenagers with mutational falsetto in preand post-therapy conditions showed mean f0 values of 221 Hz and 119 Hz, respectively.…”

“…A study with ten teenagers with mutational falsetto in preand post-therapy conditions showed mean f0 values of 221 Hz and 119 Hz, respectively. These values are very close to those found in this research (222.4 Hz and 120.9 Hz) (9) . Researchers (10) acoustically analyzed the voices of 15 individuals with mutational dysphonia in pre-and post-therapy conditions, and verified vocal quality improvement and decrease of f0 after therapy.…”

“…These findings agree with literature that indicates speech-language therapy as the elected approach to treat mutational dysphonia, showing good results in the improvement of patients' voices (3,(7)(8)(9)(10) . With regards to auditory-perceptual analysis, the overall grade of dysphonia (G) improved in all the participants after intervention, corroborating other studies (7)(8)(9) . The pitch parameter was different in pre-and post-therapy conditions, in all analyzed voices, and it was a distinguishing factor.…”

The most common mutational voice disorder is the mutational falsetto. The voices of four young male patients with mutational falsetto were acoustically and auditory-perceptively analyzed in pre-and post-therapy situations to verify the result of speech-language intervention. For data collection, the patients were asked to say the days of the week. Four speech-language pathologists performed auditory assessment of these emissions using auditory-perceptual parameters: overall grade of dysphonia, roughness, breathiness, strain, instability, and pitch. The emissions of each patient corresponding to pre-and post-therapy were randomly presented to the evaluators, who did not have prior knowledge of the condition being analyzed. The assessment was performed by comparison, and the evaluators should inform whether the second emission was better, worse or unchanged when compared to the first. When change was observed, they should select three auditory-perceptual parameters regarding the expressive modification. The evaluators were informed only about subjects' age and gender. Mean, maximum and minimum fundamental frequencies were extracted from each emission of the patients using the Praat Program (version 5132). Semitone values were also extracted and analyzed. Data was statistically analyzed. In the post-therapy condition, the evaluators found an improvement in the vocal quality of all patients, as well as a decrease in the mean, minimum and maximum fundamental frequencies and in the semitones, resulting in a deeper and more stable vocal pattern.

“…5,7,8 In this study, voice therapy also helped to enhance confi dence and self image of the speaker due to psycho social improvement which is confirmed by decrease in emotional component of VHI score. These findings are similar to a study done by Alam N et al 6 Further studies consisting of larger group of patients are needed with newer techniques of acoustic analysis and quality of life measures to confirm the results and to improve our understanding about mutational falsetto.…”

“…Didaticamente, as disfonias relacionadas à muda vocal ou puberfonias podem ser classificadas em seis tipos, de acordo com a característica mais evidente no quadro: mutação prolongada, mutação precoce, mutação retardada, mutação excessiva, falsete mutacional e mutação incompleta. Podem coexistir duas ou mais alterações da muda vocal em um mesmo paciente (Anelli, 1999;Behlau & Pontes, 1995b;Behlau & Pontes, 2001;Behlau et al, 2001b;Hammarberg, 1987;Prathanee, 1996).…”

Este artigo tem por finalidade discutir criticamente os aspectos fisiológicos e psicológicos da disfonia funcional psicogênica por puberfonia do tipo muda vocal incompleta, esclarecendo os objetivos da terapia fonoaudiológica e os fatores que podem interferir no prognóstico. O estudo foi realizado a partir de uma consulta sistemática a fontes clássicas e atuais da literatura científica nacional e internacional. Com base nos aspectos abordados, foi possível concluir que a conduta fonoaudiológica fundamenta-se em técnicas que visam à diminuição da frequência fundamental a partir do abaixamento da laringe. No entanto, faz-se necessário um trabalho interdisciplinar, visto que as causas deste quadro são predominantemente emocionais.
