LPC语音识别特征提取算法使用莱文森

Microsoft Speech SDK提供关于语音（Speech）处理的一套应用程序编程接口SAPI（Speech Application Programming Interface）。SAPI提供了实现文字-语音转换（Text-to-Speech）和语音识别（Speech Recognition）程序的基本函数，大大简化了语音编程的难度，降低了语音编程的工作量。

这是一个xmms功能非常强大的插件，能有卡拉OK功能，还有混响、减噪、EQ等等功能，其中混响的效果可达到一定专业水准！强烈向站长推荐！-xmms This is a very powerful plug-in, there will be karaoke function, there is reverberation, noise abatement, EQ functions, and so on, the effect of reverberation can reach a certain professional standards! Strongly recommended to the station!

一个用matlab实现的mp3解码源程序，对进行mp3开发的初学者非常有用-an achievable using Matlab MP3 decoder source of development for beginners mp3 very useful

语音降噪的M程序，原信号加噪声，进行滤波得出原始信号-M procedures, the original signal plus noise, obtained the original signal filtering

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.

The Yin algorithm was developed by Alain de Cheveigné of IRCAM-CNRS and Hideki Kawahara of Wakayama University. It allows for real-time continuous (for each sample) fundamental frequency estimation. It features a very low error rate and few tuning parameters. This implementation is a C++ template, with EMM support for faster processing. Developped in Visual C++ 6.0, but should compile with other compilers.-The Yin algorithm was developed by Alain de Cheveigné of IRCAM-CNRS and Hideki Kawahara of Wakayama University.
