I use a jabra Headset with the phone most of the time. In looking around the internet I found that you can configure the headsets to use Microsoft Voice Command with the headset rather than speaking into the mic in the phone. By default when you press the headset button it starts the inbuilt voice quick dial. I never use this anymore. This is the standard phone voice dial where you have to teach it everyone of your contacts you want to assign a voice command to.

What this registry change does is load up the voice command software instead when you press the button

Install Voice Command to the default location.
Fire up a registry editor
Go to: HKEY_LOCAL_MACHINE\SOFTWARE\OEM\VoiceCommand
Modify the string marked "path" from the default \Windows\SDDialer.exe to \Program Files\Voice Command\VoiceCMD.exe
