读取单通道pcm格式音频文件的程序，稍加修改即可作为读取较大音频文件并作相应处理，实际中笔者将该程序和其它程序结合，完成了许多先读取部分文件，在作后续处理的试验。-read channel PCM audio file format of procedures, little changes can be read as larger audio files and dealt with accordingly, in reality the author this program and other procedures, many completed the first reading some documents, as a follow-up to the test.

These are the source codes of the book, Frazier M W. "An Introduction to Wavelets Through Linear Algebra" [M]. New York: Springer, 1999. I wrote them in 2007. All the figures in the book can be reproduced by scripts. Enjoy it.

程序将文本合成为语音，并输入到一个wav文件当中-Procedures for the voice synthesis of text and enter them into a wav file

这个程序主要是用来做动态神经网络结构以记忆语音 图 2.2 是语音信号的预处理的流程图。 从图 2.2 可以看到预处理模块包括预加重， 加窗分 帧和端点检测。 前级预加重、 加窗分帧及端点检测是语音识别的准备工作， 每一个环节对整 个识别系统的性能有着重要的影响。 前级预处理主要是对信号进行一定的滤波和分帧； 加窗 分帧就是将语音信号进行分段处理， 使语音信号连续并保持一定的重叠率： 端点检测是确定 语音有用信号的起始点与终止点， 并通过一定的手段处理， 将没有意义的语音信号去除， 从 而减少语音匹配识别模块的运算量， 同时也可以提高系统的识别率。 预处理不合理或语音起
