摘　　要：在确保语音信号基音检测算法准确度和稳健性的前提下,降低其复杂度,增强实时性.首先给出了基音周期提取过程的实现框图,而后结合流程图详细阐述了提出的新算法,最后通过对仿真实验结果的分析,表明新算法在噪声环境下,仍能精确地提取基音周期.In the premise of ensure the accuracy and stability of the pitch signal, the article aims at reducing complexity and enhancing real-time. First of the pitch bining with pitch track extraction process is gived, then the proposed new algorithm in flow chart in details, the new algorithm still extracts the pitc detection algorithm of speech of all, the realization diagram this article is expounded com- h accurately and gets smooth ,in the case of noise, through analysis of the simulation results in the end.
