OpenEars has made a decent TTS engine (based on flite) but it is far from the top of the line engines offered by Acapela, Ivona, and NeoSpeech.

somethings in the air ... i coded a little project (also based on kripkens awesome speak.js) a month or so ago (in a little cabana in bolivia while i was travelling) http://lalo.li 100% client side, shareable text2speech voice messages

Read through speakGenerator to see how the data is generated I guess
