摘要
为解决男女声音识别的问题,将基音频率作为鉴别男女声音的标准,分别采用傅里叶变换和基于自相关的方法进行了语音的基音提取,并用MATLAB编写程序进行解算,然后通过分析比较得出基音频率。仿真结果表明,根据程序获得的基音频率,能够有效和较为准确地进行男女声音识别。
In order to solve the problem of voice recognition between men and women,this paper uses pitch frequency as the standard to discriminate male and female voices. The pitch of the voice is extracted by the Fourier Transform and the autocorrelation-based method,and these algorithms are programmed by using MATLAB to get the pitch frequency. The simulation results show that the voice recognition of men and women based on the pitch frequency obtained by the program can be effectively and accurately performed.
