I have been looking at VoiceCentral due to the static issue with MS VoiceCommand and BT headsets.

I sent VC a message about BT Headset support for voice recognition and this is their response:

-Currently VoiceCentral does not support Bluetooth headsets because Microsoft does not expose the necessary functions to third party software developers. We are working with Microsoft to resolve this issue and hope to have a solution available in the coming months.-
