I mean, lip reading is an iffy science as it is.
And why would you need to lip read if it can recognize voice commands anyway?
Hmm this is interesting. I "heard" 3 or so years ago that Sony was working on lip reading tech on a game that at the time was codenamed "The Getaway 3" but that tech was for next Playstation. I loled at the time. Who knows. Maybe something like that is next gen. can't say i am excited since I know it won't work properly.
I guess something like that is that Lionhead Milo guy wet dream
