在evmdm642平台下的一个语音采集-回放任务，用48K/秒的采样率采集立体声音频输入，用给定的FIR 滤波参数处理数据后再播放出来。注：内附个人整理的详细操作文档。(evmdm642 platform in a speech to the gathering-intervals task with 48 K/s sampling rate Acquisition stereo audio input, used to the FIR filter parameters for data processing later. Note : with a detailed personal finishing operations documentation.)

对语音信号进行脉冲编码调制，采用A律13折线(Voice signal pulse coding modulation, using A Law 13 polyline)

利用mfcc特性进行语音识别，分类算法为svm。(Speech recognition using MFCC characteristics)

验证码小识别源码程序，结合易语言位图支持库，调用易语言模块实现验证码识别。(Little recognition source code program , combined with easy language bitmap support library , call easy language module verification code recognition .)

说明：  基于统计模型的谱减法，程序复杂度不高，优于传统谱减法．(statistical model based on the spectral subtraction, the complexity of the procedure is not high and superior to the traditional spectral subtraction.)

基于MFCC的GMM的说话人识别，是很好的语音处理程序(MFCC of the GMM based speaker recognition, speech processing is a very good program)

蓝牙全双工语音和数据传输 蓝牙调制和跳频 蓝牙语音传输的相关程序(Bluetooth full duplex voice and data transfer Bluetooth modulation and frequency hopping Bluetooth voice transmission procedures)

c#写的语音识别程序，识别效率还算可以。且根据识别可以给出相应的识别百分比。适合研究语音识别以及tts的参考！(c# to write the speech recognition process, identify efficiency figure. And recognition can be given according to the percentage of the corresponding identification. Tts speech recognition, as well as for research reference!)
