Abstract

We propose in this study, a method allowing us to characterize a speech occurred in a stress situation. For this, we created an artificial disturbance (stress lip) and then, we analyzed the effects of stress on the acoustic parameters of the signals produced. We have developed a methodology allowing us to analyze the timing, the fundamental frequency, formants frequencies (calculated with wavelet transform methodology) and the coarticulation between consonant and vowel. These parameters are generally used to produce vector descriptors in communication systems. Articulatory interpretation of results typifies well the constraint used.
