二相码编码与码组检测，利用matlab实现并仿真

模拟语音信号的动态范围解压缩算法的matlab源码-Analog voice signal dynamic range compression algorithm solution matlab source

用于语音识别的汉语树形词典，完成了6万词汇的建树操作及相关子节点等的查询处理，主要用于指导语音搜索整个建立时间大概为3分钟-for speech recognition dictionary of Chinese tree, completed 60,000 contribution to the vocabulary and related operations, such as sub-nodes of query processing, Pronunciation guide for the main search the entire building for about three hours minutes

实现了语音回放功能，很不错的-Realized the voice playback, it is good

其中大部分采用voicebox库中的函数，需要把voicebox添加到路径中。 模板在测试程序中共有5个，通过i进行设定，命名原则：数字a，如1a 被测试对象一个，命名原则：数字b，如1b 测试程序为dtwTest 其他的都是一些函数原型，包括 dtw MFCC enframe vad

语音识别技术是2000年至2010年间信息技术领域十大重要的科技发展技术之一 语音识别是一门交叉学科，语音识别正逐步成为信息技术中人机接口的关键技术，语音识别技术与语音合成技术结合使人们能够甩掉键盘，通过语音命令进行操作。语音技术的应用已经成为一个具有竞争性的新兴高技术产业。-voice recognition technology from 2000 to 2010 among the field of information technology in 10 major technologies voice recognition is one of an interdisciplinary, voice recognition is gradually becoming the information technology a key man-machine interface technology, voice recognition technology and voice synthesis technologies enable people to get rid keyboard, through voice commands to operate. The application of voice technology has become a competitive emerging high-tech industries.

ADPCM压缩解压编码，实现部分为C语言编写，把它用C++封装为两个接口，编码和解码，方便使用。8K 16bit。-ADPCM compression decompression coding to achieve part of the C language and C Packaging it for two interfaces, Encoding and decoding and user-friendliness. 8K 16bit.

这个才是好东西，语音识别相比大家都知道，但是目前市场上出现的效果都不是太好，这个代码也是语文转换，效果还可以，但是说话不能口音太重-This one is just good thing, speech recognition compare with all know , but now, the effect that appears on market does not be too good , this code is also Chinese conversion, effect return can, but speak can not accent value too

txt2wav.rar文本语音（Text-to-Speech，以下简称TTS），它的作用就是把通过TTS引擎把文本转化为语音输出。代码示范了如何运用Microsoft Speech SDK 建立自己的文本语音转换应用程序。应该事先下载微软的语音SDK里面含微软的语音开发工具原来是sapi5.1现在好像升级了微软的MSDN上有下-txt2wav.rar text pronunciation (Text-to-Speech, hereafter refers to as TTS), its function is transforms through the TTS engine the text as the pronunciation output. How did the code demonstrate has established own using Microsoft Speech SDK text pronunciation transformation application procedure. Should beforehand download Microsoft inside pronunciation SDK to contain Microsoft the pronunciation development kit originally is sapi5.1 now looks like promotes on Microsoft s MSDN to have next
