Implementation of background subtraction algorithm using Gaussian mixture model.

语音的消噪程序，传统普减法的改进，有效去除背景噪声-Speech de-noising process, the traditional S & P subtraction improvements, effectively remove background noise

利用谱减法对语音的背景噪声进行消除，matlab仿真 仿真通过，自带录制好的语音-Using spectral subtraction of background noise on speech is eliminated, through the MATLAB simulation, with recorded speech.
