The present study aims at describing voice quality settings by means of long-term, f0 and intensity analysis of samples which integrate the material developed with the purpose of introducing the Voice Profile Analysis Scheme-VPAS in the Brazilian Portuguese context (BP-VPAS). The voice quality database was recorded in a radio studio. The audio samples were analyzed by means of the SG Expression Evaluator, a script developed by Barbosa (2009), which automatically extracts fundamental frequency (f0) and its first derivate (df0), intensity, spectral tilt (SpTt) and Long-Term Average Spectrum (LTAS). These measures have been statistically analyzed by means of multiple and non-linear regression tests. The results contemplate the correlations between perceived voice quality settings and f0 and intensity long-term acoustic measures.
