用MATLAB开发的语音识别的语音特征提取方法MF

两个使用skypeapi的示例，第一个

txt2wav.rar文本语音（Text-to-Speech，以下简称TTS），它的作用就是把通过TTS引擎把文本转化为语音输出。代码示范了如何运用Microsoft Speech SDK 建立自己的文本语音转换应用程序。应该事先下载微软的语音SDK里面含微软的语音开发工具原来是sapi5.1现在好像升级了微软的MSDN上有下-txt2wav.rar text pronunciation (Text-to-Speech, hereafter refers to as TTS), its function is transforms through the TTS engine the text as the pronunciation output. How did the code demonstrate has established own using Microsoft Speech SDK text pronunciation transformation application procedure. Should beforehand download Microsoft inside pronunciation SDK to contain Microsoft the pronunciation development kit originally is sapi5.1 now looks like promotes on Microsoft s MSDN to have next

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)

WAVE文件作为多媒体中使用的声波文件格式之一，它是以RIFF格式为标准的。RIFF是英文Resource Interchange File Format的缩写，每个WAVE文件的头四个字节便是“RIFF”。WAVE文件由文件头和数据体两大部分组成。其中文件头又分为RIFF／WAV文件标识段和声音数据格式说明段两部分。WAVE文件各部分内容及格式见附表。-WAVE as a multimedia documents used in the acoustic format, it is based on RIFF format as a standard. RIFF English Resource Interchange File Format of the initials, each WAVE document for the first four bytes is "RIFF." WAVE document from the document and data on the first two major components. The first document which is divided into RIFF/logo of WAV files and voice data formats note of two parts. WAVE part of the document content and format of the attached tables.

离散语音信号处理（麻省教材）的配套程序，其中包括最基本的语音处理程序（如谱减法，谱幅度估计，语谱图等）以及语音库。强烈推荐

SUN的ADPCM压缩解压程序,包括G.721,G.723,其中G.723又包括16bit,24bit,40bit的压缩解压-Sun ADPCM compression decompression procedures, including G.721, G.723, G.723 also includes 16bit, 24bit, 40bit compression decompression
