This may be a total "derp" moment, but I thought the voice recognition stuff only worked when you used the Playstation Camera. I was testing USB headsets that I owned so I plugged in my Logitech headset (wired version of G930) and it
1. Asked me who was using the headset
2. Immediately started taking voice commands
The ability went away when I went into a party and was using the headset for voice chat but when I went back out of the party it started working again. I was pretty impressed as it picked up what, limited, functionality it had rather well with no frustration. If they can get bluetooth headsets to work with this I think this will be a better way to do voice recognition than the camera.
