转换音频Wav到PCM PCM

Voice_Band_Audio_Processor_Interface_source_code

这是用vc++编写的程序,在语音识别中经常用用到,是语音识别的第一步:time alignment. 分别用两种方式完成:1.非递归2.递归-This a vc++ program which is useful in voice recognizing and it is also the basic of the voice recognizing .I use two ways to accomplish it:1 nonrecursion 2.recursion

该函数可以对语音信号进行加窗和分帧,简洁有效-enframe for speech signals

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。

本系统在Windows XP系统下编译通过。使用VC环境开发。(robot)-This system is compiled successfully under Windows XP,developed by vc

mp3解码源代码，音频压缩算法，vc编写，包括layer3编码源码和mp3解码源码两部分-MP3 decoder source code and audio compression algorithm, vc preparation, including source code and layer3 MP3 decoder source of two parts

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.
