Really, Dragon can't cope with someone sitting ten feet away and speaking at the same time? So I guess no listening to radio, either. Is it just the specifics of speech or is it that noise sensitive.

Maybe someone should do some kind of voice rec "groupware" then, where the relatively louder results of the other person are used to filter out false positives on my end...

The mic I used in the video can actually cope with very noisy environments. With lesser mics, speech recognition is useless with even mild background noise.
