Bethesda have announced that the Kinect patch for Skyrim will be available sometime today.
You will be able to shout in both Dragon and English so ‘Fus Ro Dah’ and ‘Unrelenting Force’ will work equally well.
You could try exclaiming ‘Fix All Bugs’, you never know it might work.
A full list of voice commands can be found here.
