What differentiates this technology from other machine translation systems is the fact that it is able to deal with spontaneous speech, rather than requiring a limited vocabulary and perfect diction.  The technology even employs a morphing system that changes the image of the speaker’s face so that his or her lips appear to be forming words in the language the listener hears.  While still experimental, the system may ultimately be employed not just in video conferences but in live meetings and even on telephone calls.
