- Résumé : Concerned with pathological voice assessment, this paper aims at characterizing dysphonia in the frequency domain for a better understanding of related phenomena while most of the studies have focused only on improving classification systems for diagnosis help purposes. Based on a first study which demonstrates that the low freqencies ([0-3000]Hz) are more relevant for dysphonia discrimination compared with higher frequencies, the authors propose in this paper to pursue by analyzing the impact of the restricted frequency subband ([0-3000]Hz) on the dysphonic voice discrimination from a phonetical point of view. In this sense, performance of the GMM-based automatic dysphonic voice classification system is measured according to different phoneme classes and frequency bands ([0-3000] and [0-8000]Hz).

- Résumé : For fifteen years, we have developed and studied different techniques and methodologies to assess voice quality in a clinical context. This paper exposes recent results obtained by complementary approaches. 449 speakers (including 391 dysphonic patients) participated in the experiment where voice quality was evaluated by (1) perceptual voice assessment performed by a jury and (2) instrumental voice assessment using acoustic and aerodynamic data. Results showed that a combination of 7 instrumental measures allowed the classification of 82% voice samples in the same grade as the jury. We evaluate the methodological situation and we also discuss some theoretical aspects which are often forgotten in the performance race.
