语音信号分帧加窗程序，许多程序包里都没有的！-Speech signal windowed framing procedure, many programs do not have the bag!

HTK3.4（HTK最新版)源码 + 可执行文件 + HTK book + 其他少量HTK资料（含中文）-HTK3.4 (HTK latest version) source+ Executable file+ HTK book+ Other HTK a small amount of information (including Chinese)

又下来传一个基音检测的论文,一共4片,包括英文文献!!一起学习-Further down the mass of a pitch detection of the papers, a total of 4, including English literature!! With learning

这是一个窗函数分帧函数，它在melcepst这个函数中被调用。（当然也可以用在平常的分帧）-This is a window function and sub-frame function, it melcepst this function is called. (Of course, can also be used in the usual sub-frames)

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.

这是一个的matlab的对语音处理文件。、 包括录音，MFCC特征，VQLBG法的库的形成，与非特定人的识别问题。-This is one of the matlab files for voice processing. , Including the recording, MFCC characteristics, VQLBG law, the formation of the Treasury, with non-specific identification of people.

一个mp3的解码程序，c语言实现。其中只对layer III 进行解码。-A program of mp3 decode,programmed by c language.It can only decode layer 3.
