Windows Mobile - voice control + speech synthesis (text to speech)

I've got Windows Mobile 6.5 application and I need to add simple voice control (like "yes" and "no" commands recognition). I'd also like to add possibility of reading text displayed on LCD.

I'd appreciate any suggestions about possible solutions for such problem. 开发者_开发知识库Are there any free libraries with described functionalities?

Thanks for any help, MattheW

Luckly there are also open source alternatives: - espeak for speech synthesis - PocketSphinx for speech recognition

Windows Mobile supports SAPI 5.0, which supports command-based speech recognition and text-to-speech.
