MATLAB对语音信号加噪去噪处理，对语音信号进行高通、低通滤波-MATLAB adding noise to the speech signal denoising processing, speech signal high-pass, low-pass filtering

利用MATLAB执行LPC分析和合成语音文件和显示原始语音信号通过滤波,提取LPC的错误(激发)信号,然后使用逆LPC的滤波误差信号,可以完全恢复原始语音信号。-This MATLAB exercise performs LPC analysis and synthesis on a speech file and shows that by filtering the original speech signal, extracting the LPC error (excitation) s
