可以对处理后的语音进行一个客观上的评判，提供客观评价因子。(It is possible to make an objective evaluation of the processed speech and provide an objective evaluation factor.)

双通道语音增强算法，消除环境噪声。采用归一化自适应方法，噪噪声抵消10dB，语音保持较好可懂度。(The dual-channel speech enhancement algorithm to eliminate ambient noise. Using normalized adaptive noise noise offset by 10dB, and the voice to maintain good intelligibility.)

基于麦克风阵列用盖尔圆法进行信源数目估计。输入数据位麦克风采集的信号，阵元数目为10.(Based on microphone array，the number of sources is estimated by Gerschgrid method. Input data is obtained by microphone array and the number of array elements is 10.)

语音信号的矢量量化，其中vector_quantization.m为读取音频文件，转换成语音帧，求lpc及lsf参数以及进行矢量量化的主程序，a_lsf_conversion.m为主程序调用的lpc转lsf参数的子程序，INLS1.wav为音频文件。(Vector quantization of speech signals, wherein vector_quantization.m to read audio file, converted into speech frames, seeking lpc and lsf parameters and vector quantization of the main program, a_lsf_conversion.m main program calls a subroutine parameter lsf lpc turn, INLS1.wav as an audio file.)
