Banco de vozes brasileiro nas variações das emoções (EMOVOX-BR): elaboração e validação

Abstract

This dissertation expanded studies on the theme related to voice and emotions from the creation and validation of a voice bank with emotional variations of individuals from the Brazilian population. This dissertation is divided into two articles: 1) It is an observational and cross-sectional study that aimed to validate the construction of a voice bank and to list the findings of the perceptive evaluation of expert judges in voice and 2) It is a cross-sectional study, descriptive and quantitative that proposed to analyze acoustic parameters of a Brazilian Bank of Voices in the varied emotions (EMOVOX-BR). The first study had 182 audios produced by actors or students of Performing Arts, who obtained better quality of signal noise ratio (SNR). These underwent auditory perceptual evaluation by speech therapists with voice expertise. It is concluded that the speech therapists were able to identify the emotions, valence and power, besides realizing the voice and speech modifications in the varied emotions. In the second study were selected the 39 audios that obtained better results of the analysis of the degree of intra-audios reliability and inter-judges agreement. The fundamental frequency (F0), mean, deviation, minimum and maximum measurements were extracted; jitter; Shimmer; harmonic-to-noise ratio (PHR); intensity; mean and maximum glottal extraction (GNE). The results obtained allow identifying characteristics of important variations in acoustic parameters in the expression of emotions through voice.
