Abstract

In this work, the general characteristics [2] of a speech signal have been presented and described, and they have been organized judiciously according to the different aspects [5] that can be contained and characterized by such a signal, and Cited various tools [10] that are currently used in a signal, to arrive at a clear and fairly complete description of the latter. Indeed, there are a large number of characteristics that can be extracted from the speech signal; we cite the acoustic, phonetic, morphological characteristics ... Also those which make it possible to discriminate particular classes [8] sound. However, given our goal of a complete description of the speech signal, we will focus more on general characteristics not related to particular classes. Finally, the speech signal can be processed by a set of mathematical and physical tools [8], also via various acquisitions and editing equipment. Once the processing steps have been completed, acoustic vectors [10] will be present which will facilitate their use for recognition [3].
