The software code that enables the physicist Stephen Hawking to speak through a computer was open to the public on the Internet by its creator, Intel. The program, which can now also be downloaded for free by anyone, interprets visual signals and translates them into words, which are then “spoken” by a synthesized voice.

Intel developed the program, originally, especially for Hawking, but she was used by others affected by motor neuron disease (affecting the cells that control muscle activity).
Intel expects the ACAT, which runs on Microsoft Windows 7 and above, can be perfected by researchers who develop new interfaces for people suffering from diseases such as ALS (lateral sclerosis amyotrophic), which affects Hawking.
The program and the complete source code were published on GitHub programming sharing site.
Choose sensor
Intel told the BBC that the software can perform other functions besides sending texts for a speech synthesizer. “We have menus to access different parts of the computer,” said Lama Nachman, chief engineer. “If you want to use Word, surf the internet and talk you can use the ACAT for this.”
She added that the team tested various sensors, and hoping that developers try other options appropriate to the needs and abilities of each patient. “We also have a sensor [movement] called accelerometer for patients who can use just your finger, and one button system for those who can push buttons,” she said.
The Disease Association of Motor Neuron (MND Association) UK praised Intel’s initiative.
Paper and pen
“Help keep the communication of a person with this disease can be as simple as using pen and paper. But as the disease progresses, people often lose the use of hands too, “said Karen Pearce, assistance director of the MND Association.
“This is where cutting-edge technology to AAC (Extended and Alternative Communication, which helps people with disabilities) can help, but it is vital that speech and language therapists assess the best options for the famílias.Vai be exciting to see how it will work this open source approach, “he says.
The “AAC is a key part of my life. Unlike medical research, technology is advancing very quickly, and it is encouraging to see new things popping up every year,” said Euan MacDonald, who suffers from motor neuron disease and makes assessments on disabled access at Euan’s Guide site. “The more technologies that help us to express what we think is better,” he said.
