short-circuit detector

An improved speech/ silence detector is developed by combining a noise parameter estimation method based on short time stationarity of speech signal with a statistical model based speech/ silence detection method.

基于语音信号短时平稳性以及语音信号和噪声的统计模型，提出了一种语音信号有声/无声的检测方法.该方法可对所有语音短时帧更新噪声参数的估值，因而提高了检测的准确性。
