Characterization of the Pathological Voices (Dysphonia) in the frequency space
Résumé
This paper is related to the dysphonic voice assessment. It aims at studying the characteristic of dysphonia on the frequency domain. In this context, a GMM based automatic classication system is coupled to a frequency subband architecture in order to investigate which frequency bands are relevant for dysphonia characterization. Through various experiments, the low frequencies [0- 3000] Hz tend to be more interesting for dysphonia discrimination compared with higher frequencies.
