Descrição da qualidade de voz por meio de proposta de avaliação com motivação fonética

Abstract

To describe the voice quality of a group from a phonetic perspective. Method: 60 samples of speech were evaluated under perspective of the VPAS-BP script. All speech samples were edited by using the program PRAAT. The signal to noise ratio was calculated to guarantee the quality of the sound recorded, to permit an efficient perceptual assessment. After that, 40 seconds of each sample was edited and grouped into a script of perception. 20 samples were randomly selected and repeated to ensure reliability of the judge who subsequently evaluated these samples. This script grouped the speech samples and randomly redistributed them, it assured that the judge did not have access to his own answers at the time of the replications. The perceptual analysis was held by a speech pathologist expert in voice, with more than three years of experience in the application of the VPAS-BP script. Results - In this study, harsh voice setting was present in the majority of the samples, and it appeared in a great correlation with whisper and laryngeal tension. It was observed the interdependence of some voice quality settings and some aspects of the dynamics of the voice. Conclusion: It was possible to describe and to detect some combinations between settings of quality of voice and laryngeal and vocal tract tension that can signal some voice problems
