The Phonatory Deviation Diagram: A Novel Objective Measurement of Vocal Function

Abstract: Aim: To identify the discriminative characteristics of the phonatory deviation diagram (PDD) in rough, breathy and tense voices. Methods: One hundred and ninety-six samples of normal and dysphonic voices from adults were submitted to perceptual auditory evaluation, focusing on the predominant vocal quality and the degree of deviation. Acoustic analysis was performed with the VoxMetria (CTS Informatica). Results: Significant differences were observed between the dysphonic and normal groups (p < 0.001), and also… Show more

“…Thus, the shorter the period of singing voice development, greater will be the perceived vocal disadvantages 15,16 . However, one should take into account that this study includes mostly individuals over 45 years old, age after which begins the presbylarynx process, which constitutes the aging of laryngeal structures, leading consequently to varying vocal impacts 17 .…”

“…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) .…”

“…Sabe-se que as pesquisas que envolvem avaliações perceptivo-auditivas, geralmente tem mais de um juiz (BELE, 2005;ENGLERT et al, 2015;FINK et al, 2015;MADAZIO;LEÃO;BEHLAU, 2011;KIM;KIM, 2015;MARYN et al, 2010;NEMR et al, 2012;TEIXEIRA;BEHLAU, 2015), não havendo um consenso quanto ao número de juízes indicado.…”

“…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).…”
