| 摘 要： | 基音周期是语音信号最重要的参数之一,旨在比较基音周期提取过程中的带通滤波和中心削波两种方法.并且在此基础上比较自相关函数和平均幅差函数两种基音周期检测算法.经过实验,明显得出:综合带通滤波和中心削波两种方法之后,从而得到改进后的基音检测方法,能够更准确更有效地提取到语音信号的基音周期.

| Abstract: | Pitch Contour was one of the most important speech-signal parameters,it was designed to compare with two methods between band-pass filter and center-wave absorber in the process of detecting the pitch.On the base of it,it also discussed the distinguish between ACF and AMDF.The result of experiments presented,after integrating band-pass filter and center-wave absorber,a improved pitch detection method would detect the pitch more accurately and more effectively. |

| Keywords: | pitch contour band-pass filter center-wave absorber ACF AMDF |
