采用自相关法提取基音周期，提取周期与实际值误差较小(Using autocorrelation method to extract the pitch period extraction cycle with the actual value of the error is smaller)

ga的一个仿真例子程序，还不错，用起来效果比较好，需要自己根据项目情况写适应度函数(ga a simulation example of the procedure, but also good to use effect is better, the basis of project information required to write their own fitness function)

用Matlab以及c语言求语音序列的倒谱 这某段语音信号求FFT、取模、取log、IFFT得到倒谱，并画图。选取一段进行分析，分别对浊音和清音各自求倒谱。(Using Matlab, as well as for c language serial Cepstral voice that voice signal for a certain period of FFT, check mode, check log, IFFT been cepstrum, and drawing. Select a section of the analysis, respectively, and the voiceless to voiced their demand cepstrum.)
