Abstract

Sintetizador de voz, métodos para sintetizar y mejorar una voz sintetizada y los correspondientes dispositivo de radio y señal de síntesis. Se describen un post-procesador (317) y un método substancialmente para mejorar voz sintetizada. El post-procesador (317) actúa sobre una señal ex(n) derivada de un generador de excitación (211) que comprende típicamente un libro de códigos fijos (203) y un libro de códigos adaptables (204), siendo formada la señal ex (n) a partir de la adición de salidas escaladas del libro de códigos fijos (203) y del libro de códigos adaptables (204). El post-procesador actúa sobre ex(n) añadiéndose una señal escalada pv(n) derivada del libro de códigos adaptables (204). Un factor de ganancia o de escala p es determinado por coeficientes de voz introducidos en el generador de excitación (211). La señal combinada ex (n)+pv (n) es normalizada por la unidad para control de energía adaptable (316) e introducida en un PLC o filtro de síntesis de voz (208), antes de serintroducida en una unidad de proceso de audio (209). Figura 3.
