Stephen Hawking communicates through a computer system that simulates human speech. The computer is mounted on his wheelchair. Hawking interfaces with the computer through a program called EZ Keys, written by Words Plus Inc. Hawking cans the keyboard with a cursor that he manipulates by moving his cheek muscles, one of the few muscles in his body that Hawking still has control over.
Stephen Hawking was able to type using a specially designed computer system. He used a switch attached to his glasses, which allowed him to select letters and words on a computer screen. The computer then generated synthesized speech based on his selections.

The "why" is probably for historical reasons. In general, several words are spelled differently (compared to the U.S.), not only in Canada, but in Great Britain as well; this is usually known as the "British spelling". Some changes are meter --> metre, liter --> litre, and other similar words. Another large group of words whose spelling changes is color --> colour, labor --> labour, flavor --> flavour, etc. (I put the American U.S. spelling first, the British spelling second, in these examples.)
