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, seeki

已知语音文件求出其LPC系数后，调用a_lsf_conversion.m函数求其对应的LSF-Known find their voice files LPC coefficients, call a_lsf_conversion.m corresponding LSF function evaluation
