语音信号的G.711编码。 The source code has been modified by simplifying the ADPCM algorithm to increase running speed. Here, the quantizer scale factor, y(k), is determined by "unlocked" factor yu(k) only. The factor yl(k) and speed-contral factor al(k) are ignored.-G.711 speech signal coding. The source code has been modified by simplifying the ADPCM algorithm to increase running speed.

很好的语音识别程序！可能对有些人有用！-excellent source for speech recognition.It can be helpful for somebody

基于matlab 提取语音信号中的特征参数mfcc的源程序。-Matlab-based extraction of speech signal in the MFCC feature parameters of the source.

Based on short-term energy detection and short-term cross zero rates detection in speech reorganization,the paper presents two-threshold endpoint detection.In addition,an accurate speech segmentation algorithm is achieved with the wavelet transform and statistics signal frequency domain characteristics.using cepstrum transform and cepstrum distance with the background noise,the paper achieved the speech segmentation algorithm.Analysis and Implementation of Speech Endpoint Detection
