Abstract :
This paper describes an automatic speaker recognition method for telephone speech, using acoustic processing of a single trisyllabic Portuguese word. Cepstrum coefficients are extracted from the linear predictive coefficients and no further processing is needed. In this method, the traditional classification method (non-Euclidean distance measurement) was efficiently substituted by a multi-layer neural network with encouraging results
