基于HTK的命令字识别系统

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。

从说话人的语音信号中提取说话人的个性特征是声纹识别的关键。主要介绍语音信号特征提取方法中的Mel倒谱系数 -From the speaker s voice signal to extract the speaker s personality traits is the key to Voiceprint identification. Mainly introduces the speech signal feature extraction method in Mel cepstral coefficients

很好的语音识别程序！可能对有些人有用！-excellent source for speech recognition.It can be helpful for somebody

线性量化。读取WAV文件，用不同的比特数量化，抽样频率在8khz-Linear quantization. Read WAV files, with different number of bits, the sampling frequency of 8kHz

很多人不会在windows里编译htk,因此所有htk3.2.1的程序在windows里编译了一次,可以在命令窗口下直接使用这些指令.-many people will not compile the windows Lane HTK, all the procedures htk3.2.1 windows Lane compiler, the one window in order to use them under direct orders.

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)
