基于倒谱距离—频带方差的端点检测方法

Endpoint Detection Method Based on Cepstrum Distance-Frequency Band Variance

为了提高语音信号端点检测的准确率,提出了一种基于倒谱距离—频带方差的检测方法。该方法将语音信号倒谱距离和频带方差结合起来,作为检测语音信号起始位置和终止位置的参数。仿真实验表明,该方法比传统方法更有效、更优越,能够比较准确地检测语音信号。

In order to increase the accuracy of speech endpoint detection, the speech endpoint detection method based on cepstrum distance-frequency band variance is proposed. The speech signal cepstrum distance and frequency band variance is combined as a parameter to detect the starting position and ending position of speech signals in this method. Simulation ex- periment shows that this method is more effective and superior than traditional methods, which could comparative accuratly detect speech signal.
