The front-end used in many speaker recognition systems extracts, from the input speech signal, a set of coeficients based on a mel-cepstrum technique. This paper addresses the problem of efficiency of melcepstrum coeficients in a speaker recognition system and suggests a technique permitting an appropriate choice of these coeficients. It is shown, by the results obtained, that this technique can significantly increase the performance of a speaker recognition system.
