There have been two issues I have been dealing with in VC for a while now. Just now getting around to looking at it.
1) In XBMC Vox will randomly pause the playback of the song or movie I'm playing. I'm using an amulet remote so I thought it might be it, but I verified many times that the remote was not touched or bumped and had no red light (or any) when the XBMC pauses. The random pausing sometimes is the only inadvertent commands being sent to from VC.
2) The other huge headache VC gives me is how it won't respond sometimes until I restart it. EXAMPLE: I'll come home after a workout leaving the computer on a few hours. I'll try to use Vox and it won't respond. As soon as I restart it, everything is fine. It just seems to ignore any voice commands I give up (in green listening mode of course). I haven't tried to re-install VC yet.
James I am hoping you have some ideas bud.
