Eh...
Watching the video, there's really noticeable lag between the command and activation. I'll give it a shot with the demo but it seems to be about the same delay as pausing and using the menu commands.

This really seems more like a feature for people who are interested in picking the 'Action' style playthrough of ME3 - the kind of people that hate RPGs and Menus and shouldn't be playing Mass Effect to begin with.

halo CEA had some strange voice commands too. the "analyze" and "scan" commands for adding intel to your library is pretty cool, but the rest are useless.

i like the idea of giving your team mates commands via voice commands. all the combat commands seem really silly though. timing is so important in combat that it just doesn't seem practical at all.

Test this guys, can you say this sentence faster than pressing a button on the controller - "Yeah, I guess we should use Kinect for voice-activated gimmicky stuff like this, that is pointless".

Been mulling it over and a major concern comes to mind - can you still combine powers with the Kinect commands? If I tell Liara to do Singularity, can I command Miranda to hit it with a Warp in time to actually cause the Singularity to detonate? Will it know to combine the powers?

Will I have to sit there highlighting guys in real-time to make it work? Because it seems like a whole less work (and safer on higher difficulties) to just pop that menu open and look around.

I have a simple test for Voice Commands. If it can understand the phrase "Liara! MOVE YOUR BLUE *** OUT OF THE WAY!" and Liara actually moves out of the way, then I will call Kinect voice commands a success.

Until then, this is nothing more than compounding the embarrassment of the "Go, Go Gadget Lightsaber!" Epic fail of the Kinect Star Wars demo last year. It's nothing more than fluff. Xbox is so desperate to make Kinect something more than a Dance game interface, they'll throw in any kind of goofy gadget to any blockbuster game and claim it's "Better with Kinect."

This is supposed to be cutting edge video gaming, and all they can do for voice commands are simple one word commands? This kind of voice recognition has been around since the late 1990's. We've got two year old iPhone apps with more intuitive voice recognition than this.
