Stephen Hawking's New Speech System Is Free and Open-source

An anonymous reader writes: Stephen Hawking and Intel have worked together for the past several years to build a new communication system for those suffering from diseases that severely impair motor function. The system is called ACAT (Assistive Context Aware Toolkit), and it will be free and open source. Hawking's previous system had been in use for over 20 years, so the technological upgrade is significant. His typing rate alone has doubled, and common tasks are up to 10 times faster. ACAT uses technology from SwiftKey, a cell phone keyboard enhancement.

"Over three million people around the world are affected by motor neuron disease and quadriplegia and because the system created for Hawking is based on open-source software, it could potentially be adapted to suit many of them. Different functions can be enabled by touch, eye blinks, eyebrow movements or other user inputs for communication. Hawking and Intel hope that because the system is open and free it will be adopted by researchers who will want to use it to develop new solutions for those with disabilities."

    RTFA (second link): they've tried it, and couldn't get a strong enough signal from Hawking.

    From the second link:

    Wood showed WIRED a little grey box, which contained the only copy of Hawking's speech synthesiser. It's a CallText 5010, a model given to Hawking in 1988 when he visited the company that manufactured it, Speech Plus. The card inside the synthesiser contains a processor that turns text into speech, a device that was also used for automated telephone answering systems in the 80s.

    "I'm trying to make a software version of Stephen's voice so that we don't have to rely on these old hardware cards," says Wood. ...

    Hawking is very attached to his voice: in 1988, when Speech Plus gave him the new synthesiser, the voice was different so he asked them to replace it with the original. His voice had been created in the early 80s by MIT engineer Dennis Klatt, a pioneer of text-to-speech algorithms. He invented the DECtalk, one of the first devices to translate text into speech. He initially made three voices, from recordings of his wife, daughter and himself. The female's voice was called "Beautiful Betty", the child's "Kit the Kid", and the male voice, based on his own, "Perfect Paul". "Perfect Paul" is Hawking's voice.
