Abstract

Un procedimiento para obtener una estimación de varianza en componentes de ruido de una señal de audio formada por componentes de voz y de ruido, que comprende: obtener dicha estimación de varianza en componentes de ruido de una señal de audio a partir del promedio de estimaciones previas de la amplitud de las componentes de ruido de la señal de audio, en el que las estimaciones de la amplitud de las componentes de ruido de la señal de audio que tienen valores mayores que un umbral se excluyen de o se ponderan con un valor bajo en el promedio de las estimaciones previas de la amplitud de las componentes de ruido de la señal de audio, y en el que cada estimación de la amplitud de las componentes de ruido de la señal de audio es una función de una estimación de varianza en las componentes de ruido de la señal de audio, una estimación de varianza en las componentes de voz de la señal de audio y la amplitud de la señal de audio.
