给信号加入噪声时，信噪比的控制小程序，基于matlab。

ETSI发布的用于研究分布式语音识别的前端降噪算法-ETSI issued for the study of Distributed Speech Recognition front Noise Reduction Algorithm

程序名：Guard.c //该程序是特定人语音识别 //在程序中通过三条语句的训练演示特定人连续音识别，其中第一条语句为触发命令。 //在程序开始首先训练触发命令，然后提示训练两条命令，训练完毕开始语音识别。 //当识别出触发名称后，发布命令则会听到应答-procedures Name : Guard.c// The procedure is a specific person voice recognition// procedures adopted by the three phrases of training people for a specific demonstration of the sound recognition, the first of which triggered an order for the statement.// First in the beginning of the proceedings training trigger orders, and then suggested training two orders completion of the training started to voice recognition.// Trigger out when name recognition, will be issued an order to hear responses

ITU-T G.729A标准源代码解码端，已创建工程文件，方便初学者，已测试，运行良好-ITU-T G.729A standard decoder source code, project files have been created for beginners, have been tested, well-functioning

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.

将文本按照标点符号分开的程序源码,可以把分开后的源码分开保存到文本文件中.为方便语音识别软件的制作而开发.-punctuation separate proceedings source, can be separated from the source to maintain separate text file. For the convenience of voice recognition software production and development.

采用小波变换实现带噪语音信号的增强，供参考-Wavelet transform realize Noisy speech signal enhancement, for reference

一个基于DTW的的孤立词的语音识别系统，采用率为800，可以识别六个字左右的短语，是特定人的识别系统。运行时请更改工作目录：工程->设置->调试->更改工作目录即可-The DTW-based isolated word speech recognition system, using rate of 800, can identify words around the phrase, a specific person

语音识别中的通道自相关函数，matlab版。自己编的，通过测试-Speech Recognition access autocorrelation function, Matlab version. His series, testing
