Microsoft Research presents bilingual avatars at the TechFest 2012. The Monolingual TTS can translate the user's speech into another language and in a voice that sounds like the original user's. Imagine, the tool recognizes your native tongue, translates it to a different language, and plays it with a great deal of approximation of what you sound like!
The demo at Microsoft this week used an avatar of Craig Mundie, Microsoft's chief research and strategy officer, to illustrate the system in action.
