You cannot change the laws of physics. The further a microphone is from one's mouth, the stronger the pickup signal has to be because your voice drops off geometrically. Therefore the stronger pickup signal of an Omni directional microphone is also going to pick up stray sounds in your environment. This will make it anywhere from difficult to even more impossible for Dragon to recognize your speech as words. This is why close talk microphones work best for speech recognition. As a matter of fact, even the best noise canceling microphones work better in quiet environments than non noise canceling microphones.

Great minds make great strides. I think your project is impractical. Had you enough money, processing power and time it might be possible.

 

I have read on another web page something about speech analytic tchnology, that is used to transcribe telefon conversations in some callcenter software. Do you know if this is the same principle used in DNS? Could maybe this be a solution?

Why don't you contact Nuance (they manufacture Dragon) and ask.

Impractical and would be a waste of money. Speech to Text speech recognition uses large speaker dependent vocabularies to achieve high accuracy. This means to work well (text produced is understandable), each user needs to train their individual speech profile. In addition, best results occur when speakers train themselves to enunciate each word and speak in phrases, not conversationally.
