说明：  求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。(The short-time zero-crossing rate, short-time energy and short-time autocorrelation characteristics of speech signal are solved, and the experimental results are analyzed. The pitch period and resonance peak of speech signal can be analyzed by the parameters obtained by time-domain analysis method.)

布谷鸟搜索(CS)算法是根据生物界中布谷鸟的寄生繁殖机理而提出的一种仿生智能优化算法，由于布谷鸟搜索算法具有优秀的全局搜索和局部搜索能力，并且控制参数少，收敛速度快(The Cuckoo Search (CS) algorithm is a bionic intelligent optimization algorithmbased on the mechanism of biological reproduction in parasitic cuckoo proposed. Dueto the advantages of the excellent global search and local search capabilities, fastconvergence, less control parameters,)
