Abstract

Método para procesar parámetros de señales de voz codificados por un codificador con información de los estados, comprendiendo dicho método las siguientes etapas: - decodificación (320) de los parámetros de voz codificados utilizando un decodificador con información de los estados, - procesado (330) de los parámetros de voz decodificados, y - recodificación (340) de los parámetros de voz decodificados procesados, caracterizado porque los parámetros de voz decodificados procesados se vuelven a codificar utilizando un segundo codificador con información de los estados, y porque el método comprende además las siguientes etapas: - actualización (350) del estado del decodificador que tiene información de los estados por lo menos parcialmente con el estado del segundo codificador que tiene información de los estados, y - sustitución (360) de por lo menos un parámetro de voz codificado con un parámetro de voz que se ha vuelto a codificar para producir parámetros de voz codificados procesados.
