So far Ive not been able to find either of my chargers for my bluetooth headsets so I have not been up to try it yet,
I have found firefox and other software like VLC media player dosent work that great with speech recognition which is a shame because speech recognition seems to work really well for dictating and picks up how you say certain words very quickly,
I would have thought it would have been easy enough to implement a learn feature where you could record button clicks and give them a vocal name so you could teach speech recognition what "play" or "pause" is in VLC player,
you could also teach it the names of tabs in firefox or in fact anything i guess, i really cant see it being that hard and im a bit suprised MS hasnt already done it.
at the moment i dont think controlling the pc with speech really works that well, but it could.
