Abstract

Un aparato (100) de codificación de voz para emitir primeros datos codificados que corresponden a una señal de voz que contiene un componente de voz y segundos datos codificados que corresponden a una señal de voz que no contiene el componente de voz, comprendiendo el aparato (100) de codificación de voz: una sección (102) de codificación que está adaptada para codificar una señal de voz introducida en unidades de sección predeterminadas y generar datos codificados; una sección (106) de determinación que está adaptada para determinar si la señal de voz introducida contiene o no el componente de voz por sección predeterminada; y una sección (104) de síntesis que está adaptada para obtener los primeros datos codificados y los segundos datos codificados llevando a cabo síntesis de datos de ruido para, de los datos codificados, únicamente los datos codificados generados desde la señal de voz introducida de una sección de voz inactiva determinada que no contiene el componente de voz; caracterizado porque la sección (104) de síntesis está adaptada para sustituir un bit de los datos codificados generados desde la señal de voz introducida de la sección de voz inactiva con los datos de ruido.
