Fantastic story from the SwiftKey blog:

SwiftKey built a personal “language model” for Professor Hawking based on his extensive works – including documents not published in the public domain. The software learns from him to ensure it predicts contextually relevant words. It is also able to analyze the content of the specific book or lecture that he might be working on, further tailoring its predictions and autocorrections.

SwiftKey estimates that their technology has “roughly doubled” Professor Hawking’s speech rate – all because SwiftKey can understand how he uses language. I found SwiftKey’s predictions and personalizations based on social accounts to be impressive in their iOS 8 custom keyboard, but this is a whole new level (and SwiftKey says they’ve been collaborating closely with Intel for this, too).
