Flex Text to Speech Program

I am developing a Adobe Flex Application which speeches some given text inside a text box. Here am supposed to use an inbuilt function or something else, because I dont want to give an outside link to convert the text to speech since I开发者_开发问答nternet connection will not be available. Sample program written in Air are also applicable Can any one post some sample code or link? Thanks in Advance

I ported a HMM based TTS engine to Flash using the Alchemy compiler. Demos, explanation and code are here:

I expect that the simplest way will be get some external executables and wrap them into Air or even rewrite in like http://labs.adobe.com/technologies/alchemy/ but look to platform you are oriented, the best choice will be MS TTS engine or something open source like Festival TTS engine.
