Variation of voice disorders among speakers in the database TIMIT and TIMIT

In this article we present the variation of the speech signal of the database TIMIT and NTIMIT with its morphological characteristics of the speakers as well as the extrinsic variability related to the conditions of transmission and acquisition of the signal. For this study we measured the timbre and the intensity in order to choose the best indices that give us a good effect for the identification of the speakers.
