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

使用gabor变换作语音识别，下载自剑桥的实验室的网站，有兴趣的可以去网站上找资料-used for voice recognition, Cambridge downloaded from the website of the laboratory, interested parties can go to find information on the web site

自编的FASTICA程序，简明实用，并附带两个子程序以及WAV文件，-FASTICA staged by the procedures, concise and practical, and with two subroutine and WAV documents,

语音信号的频域处理,语音虽然是一个时变、非平稳的随机过程。但在短时间内可近似看作是平稳的。因此如果能从带噪语音的短时谱中估计出“纯净”语音的短时谱，即可达到语音增强的目的。由于噪声也是随机过程，因此这种估计只能建立在统计模型基础上。利用人耳感知对语音频谱分量的相位不敏感的特性，这类语音增强算法主要针对短时谱的幅度估计。 -voice signals in the frequency domain processing, voice is a time-varying, nonstationary random process. But in a short period of time can be approximated as smooth. So if Noisy Speech from the short-term spectrum estimate "pure" voice of the short-term spectrum, and reached speech enhancement purposes. As the noise is random process, which can only be estimated based on statistical models based on. Use ear perception of voice spectrum component of the phase sensitive to the characteristics of such speech enhancement algorithms targeted at the rate of short-term spectral estimation.

This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result. The method is Scale on threshold applied to the envelope for detecting scilence periods. The actual threshold is computed by multiplying threshin" by the median value of the envelope samples. The default is (.25), whichis 25 of the median envelope value over input signal .-This code is used to remove silence from a voice signal so that the recognition in voice recognition will give good result.

用VC编的用于实时地对录音的轨迹的测试。可以自动显示-It is developed with VC.It can test the trail of speech at realtime and provide an auto display.

这是解决约瑟夫圜的程序. 注释:这是本人自己编写的.不足之处请各位大哥大姐多多指教,另外请注意版权问题.-Joseph won the procedures. Note : This is my own prepared. Deficiencies Department asked Big Brother Big Sister to the exhibitions, and to copyright issues.

两个使用skypeapi的示例，第一个

该函数可以对语音信号进行加窗和分帧,简洁有效-enframe for speech signals
