首先通过手机录制一段名为“yuyin.wav”的语音，然后通过MATLAB编写程序对这段语音进行分析，分别求出这段语音短时能量、短时过零率、短时幅度以及清音和浊音的自相关函数-First phone to record a section called " yuyin.wav"　the voice, and then through the MATLAB programming analysis of this voice, this voice were calculated short-term energy, short-time zero-crossing rate, short-term rate and the voiceless and voiced the autocorrelation function
