Description: 分别取长度N=160和N’=N+K的矩形窗函数作用于语音信号上，首先对其进行中心削
波，比较削波前和削波后语音信号波形，并使得削波后的信号进行乘积并求和，计算延迟为0<K<160时的相关值，并且用得到的相关值来检测语音信号的基音周期，用MATLAB画出图形。
-Length N = 160 were taken and N = N+ K rectangular window function in the role of the speech signal, the first center of its cut
Wave, more the speech signal waveform cutting wavefront and after clipping, and that the signal is multiplied after clipping and summed to calculate the delay of 0 <K <160 correlation values , and the correlation value obtained by detecting a voice signal pitch period, using MATLAB to draw graphics.
