2. Microsoft's Voice software library

Download: http://download.csdn.net/detail/wyx100/8431269 (with instance project source code)

Two. Development Goals

Make a speech software, can read aloud text;

Multiple Voice libraries: male and female, support English and Chinese reading;

Support for selecting playback devices

Support Speech Speed selection

Support Volume selection

Three development process

1. New Wpfspeechdemo Project

File (vs Dev Platform upper left corner)----new (shortcut ctrl+shift+new)

2. Import Microsoft Voice Library

3. Create a software interface

See start Effect show

4. Software function Development

Support for voice library selection

Support for selecting playback devices

Support Speech Speed selection

Support Volume selection

Four software code
