Análises perceptivo-auditiva e acústica da voz nos momentos pré e pós fonoterapia de pacientes com falsete mutacional

Abstract

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.

Relações entre autopercepção vocal e psiquismo em um grupo de adolescentes do sexo masculino na muda vocal

“…Tal processo requer que o adolescente lide com os efeitos decorrentes da muda vocal na interação com seus interlocutores 2 . Pesquisas fonoaudiológicas 6,7,8,9,10,11 abordam diversos aspectos relacionados à muda vocal, a saber: autopercepção vocal, propostas de intervenção quanto aos cuidados com a voz, aspectos fisiológicos e psicológicos da muda vocal incompleta, análise perceptivo-auditiva e acústica da voz, impacto da muda vocal nas lesões estruturais das pregas vocais e memória da muda vocal.…”

Efeitos imediatos da técnica de vibração sonorizada de língua associada à estimulação nervosa elétrica transcutânea (TENS)

“…The understanding of the effect caused by vocal exercises on vocal quality has been the subject of many research studies which look into various vocal techniques, employing them in isolation (1)(2)(3)(4)(5)(6) or joining techniques in the therapeutic process (7)(8)(9)(10) ; in addition to comparing the effect of the application of different techniques (11)(12)(13) or in programs (14,15) . It is also possible to find literature containing review articles on the application of vocal techniques in various therapeutic proposals (16,17) .…”
