说明：  语音信号处理，语音识别，大致知道要经过预处理，特征提取，矢量化和匹配计算等几个步骤， 用matlab对一个语音信号进行滤波，分桢，加窗或者端点检测． 注：网上下voicebox工具箱，用做语音处理
(Voice signal processing, speech recognition, more or less know to go through pre-processing, feature extraction, vectorization and matching calculation several steps, using matlab on a voice signal filtering, sub-ching, windowed or endpoint detection. Note: The online toolbox VoiceBox used to do voice processing)
