这是一个用于对语音信号进行傅里叶变换，然后画图显示傅里叶变换的变换情况-This is a Fourier transform of the speech signal, and then drawing to show the Fourier transform of the transform

利用三电平中心削波自相关法实现清、浊音判定，并提取一段话音的基频参数，绘制基频曲线，并将该参数曲线合并到前面提取的短时过零率和短时能量参数曲线图中-Using a three-level center clipping from the relevant law to achieve clear, voiced determination, and extract some of the fundamental parameters of the voice, drawing the funda

利用短时自相关分析的方法先求得基音周期，同时画出此时的基音周期走势图；然后对超出基音周期均值的1/5的基音周期点进行去除，再利用中值平滑方法剔除野点，同时对剔除野点后的基音周期点进行绘图，同时求得平均的基音周期。文件中附带实验语音，可验证。-By using the method of short time autocorrelation analysis first pitch is obtained, at the same time draw the pitch at this time

语音信号处理，通过用基因检测男生和女生，用c语言编程调试语音信号，用matlab画图进行结果对比-Speech signal processing, by genetic testing of boys and girls, with the c language programming and debugging voice signal, comparing the results with matlab drawing
