摘要：In this paper, we introduce new voicing parameters to describe the speech signal and we study their effects on the classification of disordered voices. These parameters concern the fundamental frequency and the open quotient. The open quotient is defined as the ratio of the open phase by the pitch period. These parameters are calculated using the multiscale product method (MPM). The classification is operated on two pathological databases MAPACI and MEII using SVM classifiers multi-class one-against-all. We consider two types of classifications: a binary classification into normal and pathological voices for female and male speakers and a three- category classification into edema, nodule and normal voices for the female speakers only. The effects of these new parameters are studied when added to the MFCC coefficients, delta, delta second, and the energy.
