Because that's what we want in a motion control sports game.
Rare engineer David Quinn says that the studio is investigating ways to make Kinect understand 'natural conversation'.
"We pushed speech pretty hard in Sports 2, but it was also a very say-what-you-see approach; in golf, you change clubs [by saying] 'four iron', kind of thing," said Quinn, talking to Gamasutra.
"What I'd like to see and what we're investigating now is a more natural conversation way of talking to the Kinect, so you can say, 'Hey, caddy, give me a five iron,' or 'Hey, caddy, what should I use now?'"
Quinn added that he liked the way Mass Effect 3 managed to make use of voice commands.
"I think is an excellent use of speech. You can use speech in Kinect in a more core title, and it really demonstrated that. I think from here on in you'll see a lot of speech in core games."
Recent core titles to use Kinect's vocal recognition include Skyrim and the forthcoming FIFA 13 and Splinter Cell: Blacklist.
