Do folks have experience using one of these (C920-HD-Pro-Webcam) for voice command while racing and using Crewchief, (or a similar program/app)?

The mic would be about 900mm from my mouth, and I race with headphones so the only noise in the room, other than me, would be the clockwork of my G27.

(This is my second post but was told I cannot post a link because "It's my first post" so can not post a link to the camera... Please copy & Google search the product).

Thanks.
