说明：  语音系统的MATLAB仿真，实现断点见的K系数，语音能量与过零率的对比。(MATLAB simulation of voice systems, the realization of a breakpoint, see the K coefficient, voice, energy and zero-crossing rate of the contrast.)

维纳滤波器是基于最小平方的最优滤波器，有广泛的使用，用于改变信号，提高分辨率(Wiener filter is based on the least squares optimal filter, widely used for the signal changes to improve the resolution)

一种计算复杂度低的双端通话检测算法。在Benesty提出的方法上改进。减小算法复杂度缺点分析： 在自适应回波抵消中常用的双端对讲检测技术是互相关检测技术。这种算法存在一个问题，就是在某些时刻， 比如在近端干扰信号结束的时刻， 干扰信号的能量陡然下降为零，由于算法中采用了遗忘因子，信号的能量估计是缓慢减小的，因此造成检测结果的延迟。
