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...

极小边际熵等价于叉四阶累积量的平方和最小。通过迭代使四阶累积矩阵对角化，实现交叉四阶累积量的平方和的极小化。他是语音识别的重要预处理算法-minimum entropy equivalent to the marginal four bands fork cumulative amount of square and smallest. Through iterative four bands so that the cumulative matrix diagonalization, four bands to achieve cross-cumulative amount of square and the minimization. He is an important voice recognition algorithm pretreatment

频谱方差在语音信号端点检测中的应用，matlab程序，实用。-spectrum of the voice signal variance endpoint detection, the application procedures Matlab and practical.

此文件是好将声音发送到 dsk 6700 和处理的任何声音。您可以配置此代码由 dsk 海缆无源探测格式然后通过调整可以将声音发送到 dsk 的 aic23 编解码器寄存器的端口处理它，然后回 aic23 和 dsk 的输出中听到它。它是任何一个想要使用 dsk 来学习如何初始化 dsk 的好榜样。

可以讲mulaw语音数据转换成线性pcm数据-can speak mulaw voice data converted into linear data pcm

匈牙利算法的实现，比较简单，本人自己写，望大家赐教-Hungarian algorithm is simpler, I wrote it myself, hope everybody with us

基于CHMM模型的语音识别系统，能很好的实现汉语语音识别功能。

本软件是一套完全基于神经网络的语音识别处理软件。 本软件为纯绿色软件，无须安装，解压到任意一个目录下，直接运行主程序 whd.exe ，卸载时删除所在目录即可，软件不会给系统留下任何垃圾，请放心试用，但为了您的数据安全，在使用时请先将重要数据保存备份，呵呵，我信不过微软啊:) 本软件使用的是本人自行开发的神经网络处理系统，但因工程浩大，且本人穷，只能独立编写，所以现在这个试用版所使用的神经网络系统并不完整，只实现了我最初设计的一半功能，识别效果还不是很理想，正在改进中:) 但还是希望大家能对软件提出宝贵意见，我的邮箱：whd_china@etang.com 或 yinshishan@sina.com -this a completely software based on neural network speech recognition processing software. The software for the pure green software, no installation, to extract an arbitrary directory and run the main program whd.exe. unloading directory will be deleted, the software system will not leave any garbage, please rest assured that trial. But for the sake of your data security, the post will be used to preserve important data backup, Oh, I trust Microsoft ah : ) This is the software I use to the development of the neural network processing system, but the project is a huge one, himself poor, only independent prepared, the trial version now used by the neural network system is incompl

C54X语音压缩编码，采用ADPCM算法，- C54x speech compress codec,based on ADPCM algorithm.

这个程序是基于zcpa语音特征提取方法的-This procedure is based on zcpa Voice Feature Extraction Method
