本文系统的介绍了语音识别的技术及其实现方法

语音识别中的矢量量化（vq）的matlab程序，希望可以帮到需要的人-Speech Recognition vector quantization (vq) Matlab procedure, the desire to help people in need

用标准C语言实现的基于DTW算法的特定人孤立词语音识别系统，能实现汉语数字0至9个语音发音的识别，具有很好的识别性能。-Using standard C language based on the DTW algorithm to achieve the specific words were isolated speech recognition system, to achieve Chinese figures 0-9 voice pronunciation recognition, with good recognition performance.

A wonderful ica toollbox about blind source separation for the beginners

关于bp算法来逼近一个函数，还有一些关于一些简单的matlab实验程序，包括切比雪的滤波-On the bp algorithm to approximate a function, there are some simple matlab on experimental procedures, including snow Chebyshev filter

用VC编的用于显示语音的波形图，可以将microphone中的语音波形显示促。是自动的显示程序。-VC series of the show for the wave of voice, the microphone to voice waveform display promoting. The show is automatic procedures.

fir filter 程序 老师上课留的作业，在这里跟大家分享一下，希望能有所帮助-fir filter procedures teacher in the class to stay the operation here to share with you, hope can be helped

这个函数就是用来进行离散的DFT运算了。它可以指定运算的长度。-This function is used for computing the discrete DFT. It can specify the length of operations.

提供信号处理中的Rasta变换的实现过程，并可以给出相应参数。开发环境为VC。- Provides in the signal processing the Rasta transformation realization process, and may produce the corresponding parameter. The development environment is VC.

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.
