Abstract

Un método y aparato para mejorar la modulación de algunos sonidos de voz, tales como sonidos de vibrante, son proporcionados para radios que utilizan vocodificadores digitales; una corriente de voz digitalizada es muestreada y el muestreo es ajustado para determinar, detectar y mejorar nulos de vibrante en la corriente de voz digitalizada por uno o más de: cambio de trama de la corriente de entrada de voz digitalizada previo a la vocodificación, expansión en tiempo de una corriente de voz digitalizada previo a la vocodificación, compresión en tiempo de una corriente de salida de voz digitalizada después de la vocodificación, y/o mejora de modulación y filtración de la corriente de salida de voz digitalizada después de la vocodificación.
