Abstract
Las modalidades de la presente invención proporcionan un método y un aparato para detectar una señal de audio, en donde el método incluye: determinar una señal de audio de entrada como una señal de audio a-ser-determinada; determinar una relación de señal a ruido segmental (SSNR) mejorada de la señal de audio, en donde la SSNR mejorada es mayor que una SSNR de referencia; y comparar la SSNR mejorada con un umbral de decisión de detección de actividad de voz (VAD) para determinar si la señal de audio es una señal activa. De acuerdo con el método y el aparato proporcionado en las modalidades de la presente invención, una voz activa y una voz inactiva se puede distinguir con precisión.
