Intel's Trying To Help Stephen Hawking Get His Speech Back Up to Speed

Stephen Hawking is a survivor. He's been valiantly holding his own against ALS disease for 50 years now, but it's still taking its toll. The cheek-twitching mechanism he's been using to talk for the past 10 years isn't quite as efficient as it used to be.
