提取短时能量，短时过零率，清音/浊音自相关函数-Extraction of short-term energy, short-term zero crossing rate, voiceless/voiced autocorrelation function

The short term energy function can be computed by splitting the speech signal into frames of N samples

这是一个matlab程序，该程序的功能是读取一个 .wav 格式的语音信号，画出该语音信号的短时能量。主程序调用了自己编写的两个函数，函数的功能分别是对语音信号进行分帧以及计算每一帧的时间。语音分帧是语音信号处理的关键步骤，该程序可以帮助你快速入门。-This is a matlab program, the function of the program is to read a ' .wav' voice signal format, draw short-term energ
