几种语音增强关于mmse算法，维纳滤波，掩蔽增强

G.729音频压缩传输协议（ip电话）,ITU的G.729语音压缩编码标准。-G.729 audio compression and transmission protocol (ip phones) The ITU G.729 voice compression standards.

语音识别（Speech Recognition）是让机器通过识别和理解过程把语音信号转变为相应的文本或命令的技术。在课题中，通过采用DTW（Dynamic time warping, 动态时间伸缩）算法，对实现孤立词的识别进行了初步探讨和研究，实现了在MATLAB软件环境下孤立词语的语音识别，并针对DTW的主要特点及不足做出了总结。-Speech Recognition (Speech Recognition) machines is through recognition and understanding of a process which put the voice signal into the corresponding text or command technology. The issue, through the use DTW (Dynamic time warping, dynamic time telescopic) algorithm to achieve an isolated word recognition conducted a preliminary exploration and study, the realization of the MATLAB software environment isolated words of Speech Recognition and DTW against the main features and deficiencies make summarized.

语音识别，跳用JAVA里写的类，a simple test project-voice recognition, dancing with Java, written category, a simple test project

本程序实现用谱减法消除语音中的噪声，其中语音是纯净的，噪声是后加上去的，滤除效果良好-This procedure using spectral subtraction to eliminate the noise in the voice, which voice is pure, after noise is added, and filter out the effect of good

N best hypothesis document N best hypothesis as used H-N best hypothesis document N best hypothesis as used HMM

本程序可以产生一组正态模拟数，用来模拟实际生产中服从或近似服从正态分布的数据，很有用。-This procedure can generate a group of normal simulation the number used to simulate the actual production or similar to obey normal distribution of data, very useful.

基于matlab平台，采用DTW模型实现了汉语10数字的语音识别-Matlab-based platform, using DTW model achieved a 10-digit Chinese Speech Recognition

语音识别系统Sphinx2的测试音频，可以使用Sphinx_Trian对其进行特征抽取后，再利用Sphinx2系统进行识别。-Speech Recognition System Sphinx2 test audio, you can use their Sphinx_Trian feature extraction, and then use Sphinx2 system identification.

本程序采用Visual C++开发,功能为TextToSpeech.-This procedure uses Visual C++ Development, function TextToSpeech.
