At my university (KIT in Germany [1]), they developed such a system and apply it for live-translation of lectures for international students. Here's a demo: https://www.youtube.com/watch?v=DjXpKz0BiIU https://www.youtube.com/watch?v=DjXpKz0BiIU And a publication from 2008: http://isl.anthropomatik.kit.edu/cmu-kit/861_lt2007%281%29.pdf http://isl.anthropomatik.kit.edu/cmu-kit/861_lt2007%281%29.p...

So huge improvements are to be expected. [1] The professor, Alex Waibel, also has a chair at CMU.
