Abstract
Un método para procesar señal de voz antes de la codificación de una señal digital que comprende datos de audio incluye seleccionar la codificación de dominio de frecuencia o la codificación de dominio de tiempo con base en una tasa de bits de codificación que se va a utilizar para codificar la señal digital y una detección de retraso de tono corto de la señal digital.
