- 采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。-Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a pluralit

- 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
