Description: 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 plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.

Description: 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 of the graph Then the pitch is beyond the average removal of pitch point 1/5, reusing the median smoothing method to eliminate outliers, at the same time to eliminate outliers of pitch point after drawing, and calculated the average pitch period.File attached experimental phonetics, can test and verify.
