Abstract

La presente invencion se refiere a un método y sistema para el reconocimiento de locutor, el cual aplica una evaluacion de componente adaptativo a cada marco de lenguaje para atenuar los componentes del aparato no vocal y normalizar los componentes de lenguaje. Se utiliza un modelo de todos los polos de prediccion lineal para formar una nueva funcion de transferencia que tiene un componente promedio en movimiento. Un espectro normalizado es determinado a partir de la nueva funcion de transferencia. El espectro normalizado está definido como que tiene características mejoradas para los componentes del lenguaje. A partir de los componentes de lenguaje mejorados, se obtiene un reconocimiento de locutor mejorado sobre un canal.
