How technology helped Stephen Hawking speak?




Innovation and Artificial Intelligence can out of the blue affect human lives.

Stephen Hawking, one of the greatest 'theoretical physicist to have lived in the 21st century once said: "Medicine is not able to cure me, so I rely on technology to help me communicate and move."

Born on January 8th 1942, Hawking was diagonized with motor neurone disease at the age of 21.

At that time, doctors gave him a life expectancy of 2 years.

But he lived much much more than that.

The disease paralyzed most of his body parts over decades and by the late 1970s, his speech also deteriorated.


Initially he relied on partner assisted scanning, which is mechanical and slow method of communication.
In any case, as innovation progressed, in 1986, he got a PC called Words Plus, which utilized a discourse blend motor to impart.
Peddling could now just press a change to choose expressions, words or letters from a bank of around 2,500–3,000 that were checked.
The machine could produce upto 15 words per minute, but by 2005, his hands also paralyzed and he could only control his cheek muscle.

Hawking collaborated with Intel on systems that could translate his brain patterns or facial expressions into switch activation.
But the system could only produce one word per minute, which is painfully slow.
This is where artificial intelligence helped him.
Swiftkey, the London based beginning up made a product which utilized AI and utilized every one of the distributed and unpublished works of Stephen selling as preparing information to anticipate what he'll talk.
A motion detecting sensor is used to identify the movements of his cheek muscles and with that he could easily select words appearing on the screen.
The machine learning algorithm's prediction was so effective that Hawking was required only to input around 20% of the sentences and the algorithm was able to predict the rest 80%.
To this, he commented that "I can communicate better now than before I lost my voice."
Researchers are working on machines that could get brain waves, so that they can make paralysed people who cannot even control one muscle of theirs to communicate.
We are sufficiently fortunate to be living in a time span where innovation and man-made brainpower could give one of the best researcher who was paralized, the capacity to convey 

also, move, because of which he spoke with us till the finish of his life.
But when asked about AI and technology in 2016, Stephen Hawking told this:
"The ascent of incredible innovation and AI will be either awesome or the most exceedingly terrible thing at any point to happen to humankind. We don't have a clue yet which!"

The same technology and Artificial intelligence, which makes paralyzed people talk and do wonders, could mark the end of humanity if we are not prepared.
And, we're not prepared.
