基于自相关函数最大值的语音端点检测算法,即使在较低信噪比情况下采用该算法仍能较准确地检测出语音信号的端点位置。-The maximum of autocorrelation function of sonant and sonata′s autocorrelation function characteristics after autocorrelation function filtered through a lowpass are studied，this method can detect the voice endpoint exactly even in a low SNR environment.
