lpc feature voice its important for extraction 14 coofeecient

说明：  这是matlab编写的一组神经网络的程序,非常好用,只需要改动一些参数即可(It is written in a matlab neural network program, very easy to use, you can only change some parameters)

本文档分别采用A律和U律进行PCM的解码。(This document use A_law and u_law to decode the PCM code.)

说明：  加汉宁窗的低通滤波器，做出干扰信滤波前后的时域图和频谱图(Low-pass filter with Hanning window is used to make time-domain and frequency-spectrum diagrams before and after interference signal filtering.)

潮流算法，研究生作业。挺好用的，已经试过了。哈哈(Flow algorithm, graduate job. Very good use, has been tried. Haha)
