Medidas cepstrais na avaliação da intensidade do desvio vocal

Abstract

PURPOSE: to analyze if there is a correlation between the presence, intensity and type of vocal deviation and the ceptral measurements. METHODS: We used 376 speech samples of both sexes corresponding to the vowel / ε /. Specialized judge performed the auditory perceptual analysis of the intensity of the vocal deviation and the predominant vocal quality of the voice samples, from the analogue-visual scale. RESULTS: There were differences in CPPS values between the groups with and without vocal deviation. There were also differences in the ceptral values as a function of vocal deviation intensity. Differences were observed in CPPS values and spectral decline between roughness, breathness and tense voices. CPPS had a strong negative correlation with GG and GS, moderate negative correlation with GR, and weak negative correlation with GT. As for the spectral decline there was a weak negative correlation with the GS and a moderate positive correlation with the GT. CONCLUSION: There is a correlation between the presence of vocal deviation, the intensity of the deviation, the predominant vocal quality and the ceptral measurements.
