语音信号的基音检测算法（ amddf法：平均幅度差算法）可直接使用。 -The speech signal pitch detection algorithm (amddf method: the average magnitude difference algorithm) can be used directly.

运用平均幅度差函数AMDF与Viterbi算法的后处理算算法提取语音基音周期一个程序源码，效果还不错 可直接使用。 -The use of the average magnitude difference function AMDF and the Viterbi algorithm, processing count algorithm to extract the voice pitch of a program source code, the results were pretty
