Abstract

Se presenta un sistema de reconocimiento de voz (204, 206, 207, 208) que genera una rigurosidad de rechazo variable como una funcion de al menos un nivel de ruido de fondo medido durante las mediciones de la senal de ruido y entrenamiento, realizadas durante una pronunciacion de entrada hecha durante el modo de operacion del reconocimiento. Como una funcion de la rigurosidad de rechazo variable se asigna una penalizacion por entrada de palabra.
