Sustained vowels and continuous speech in the auditory-perceptual evaluation of dysphonia severity

Abstract

Based upon the results, both types of speech/voice tasks (i.e., sustained vowel and continuous speech) should be elicited and judged by clinicians in the auditory-perceptual rating of dysphonia severity.

Análise perceptivo-auditiva de vozes rugosas e soprosas: correspondência entre a escala visual analógica e a escala numérica

“…This study used the sustained vowel aiming to associate it in the future with acoustic analysis and works found in the literature using the chain speech samples (10,17) . It is known that the type of sample, speech or sustained vowel contribute to the variability of the auditive perceptual evaluation (5,7) . In sustained vowels there is a subglottic and the supraglottic condition relatively constant, whereas in continuous speech are observed temporal and spectral variations caused by start and word end, breaks, deaf phonemes, phonetic context, prosodic fluctuations in fundamental frequency and intensity, speed speech, among others (5) .…”

“…The auditory-perceptual analysis is the main vocal assessment procedure used in clinical practice by the speech therapist (1) , able to characterize the voice quality, pointing diverted vocal parameter and the degree of vocal deviation, and inferences about their social impact (2)(3)(4)(5) . On the other hand, the auditory-perceptual assessment has a essentially perceptive character, which makes it subject to mistakes and variations as it can be affected by several factors as evaluator past experience (6) , knowledge or not of the clinical data, type of assessed task -voice or speech (5,7) and protocol used (8) .…”

Aplicação de uma rede neural artificial para a avaliação da rugosidade e soprosidade vocal

“…A avaliação perceptivo-auditiva da voz, com caracterização do grau e tipo de disfonia, é considerada o padrão-ouro da avaliação vocal realizada pelo fonoaudiólogo (MADAZIO; LEÃO; BEHLAU, 2011;ROY, 2012;OATES, 2009). Por meio dela é possível descrever as características vocais e inferir sobre o impacto social da disfonia, visto que o julgamento da qualidade vocal é essencialmente perceptivo e intuitivo (MADAZIO; LEÃO;BEHLAU, 2011;ROY, 2012;OATES, 2009;SHRIVASTAV, 2003).…”

Contudo, por se tratar de uma avaliação subjetiva, está sujeita a erros e variações, mesmo entre avaliadores treinados, pois é influenciada por fatores como a experiência prévia do avaliador, conhecimento ou não dos dados de anamnese, tipo de tarefa avaliada, que pode ser de voz ou fala, (MARYN; ROY, 2012; ZRAICK;…”
