What kind of voice commands? Well, players will be able to access their "entire menu of shouts" just by speaking the magic words, so screaming "Fus Roh Dah!" at the TV will actually do something other than making you look like a crazy person. You'll also be able to give commands like "follow" and "attack" to your allies simply by speaking them, and assign hotkeys for weapon and spell combinations without having to dive into a menu.
