Diagnostical analysis of voice based on glottal pulses

Abstract

This paper deals with methods for the estimation of glottal pulses from speech signal and their analysis for finding appropriate criterions to describe a selected diagnosis. The method Iterative Adaptive Inverse Filtering is presented more in details. This method was applied to the speech under stress aimed to investigate the influence of stress by speaker on the generating glottal flow. Using two developed criterions, the best stress detection rate achieved 89 % on a small available database of speakers. ©2009 IEEE.
