 附图和源代码

效果展示

一 项目准备

1.vs2012开发平台

2.微软的语音软件库

下载：http://download.csdn.net/detail/wyx100/8431269 (含实例项目源代码)

二.开发目标

制作一个语音软件，可以朗读文字；

多个语音库：男音和女音、支持英文和中文朗读；

支持选择播放设备

支持朗读语速选择

支持音量选择

三 开发过程

1.新建WpfSpeechDemo工程

文件（vs开发平台左上角）----新建（快捷方式 Ctrl+Shift+New）

2.导入微软语音库

3.建立软件界面

见开始  效果展示

4.软件功能开发

支持语音库选择

支持选择播放设备

支持朗读语速选择

支持音量选择

四 软件代码
