- 本文通过对男性和女性声音的语音特征的研究，发现男女声的基音频率存在较大的差异，并设计了基于基音频率分析的男女声识别系统。男女声识别系统由以下三个模块电路构成：话筒放大器，低通滤波器，半波整流电路，单片机测量控制模块。话筒放大器采用NE5532P音前置芯片，对语音信号进行放大；八阶低通滤波器MAX293完成基音信号的提取；单片机STC12C5410AD实现频率测量和控制输出功能。经仿真与电路实测，男女声的识别效果良好。-In this paper, the voices of male and f

- 如果观察比较纯净的语音，可以看到韵母部分的波形呈现出一定的周期特性，这个周期被称为基音周期(pitch/f0)。通常部分声母和静音部分观察不到周期性，也就是没有基音周期。基音周期反映了发音时声门开合的频率特点。 对语音进行短时自相关处理，估计基音周期，考察各种平滑方法对自相关结果的影响。 -If you look at a more pure voice, vowel part of the waveform can be seen showing the cyclical nature
