Abstract

Un dispositivo vocoder de voz y el método correspondiente sintetiza las ondas de excitación de la voz. El método vincula la reconstrucción (216) de unobjetivo (220) creando segmentos de excitación alineados por medio de (296) normalizar, (298) correlativizar y (300) alinear un segmento de origen y unsegmento objetivo, reconstruyendo los segmentos intervinientes normalizados por medio de la 318 interpolación del ensamble entre el segmento origen y elsegmento objetivo, denormalizando (320)los segmentos normalizados intervinientes (322), una onda de excitación de los segmentos intevinientes, elsegmento origen y el segmento objetivo.
