语音端点检测，是语音压缩时提取特征参数的一个必要的过程，这个程序主要是对这个过程的一个小的程序。希望对学语音的有帮助-Extreme point detecting is a primily process to get the eigenparameter when you compressing the speech.This program is a small one,it will help for the learner.

语音信号的清浊音的提取是研究语音信号的一个必经的过程，如何提取清浊音也是很多初学者面临的问题-Detecting the voice and unvoice is a primily process to study speech signal.How to detect it is also the big problem to the most learner.

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 f
