Is there any plugin available to implement Voice recognition capability for PhoneGap app.

I came across ;

[Combine **Phono Mobile** with Tropo’s Cloud Communications API to create voice-enabled self-service applications which can include: speech recognition and text-to-speech in 24 languages, conferencing, call recording, voice transcription, and call transfers.](http://blog.phono.com/2011/07/22/introducing-phono-mobile/)

But the Tropo is a paid service, is there any open service available?
