Incredible video of Stephen Hawking speaking without his voice synthesizer has surfaced, and everyone is saying the same thing.

After being diagnosed with a slow-progressing form of motor neurone disease, the theoretical physicist, cosmologist, and novelist gradually became paralyzed and eventually lost his capacity to communicate.

Hawking was diagnosed with motor neurone disease (MND) in 1963, an incurable condition that affects the brain and nerves, eventually leading to death.

Despite his diagnosis, Hawking, who died in 2018 at the age of 76, maintained his pioneering work in theoretical physics, particularly the study of black holes.

Unfortunately, his MND gradually began to affect his speech, causing him to slur his words, and by the late 1970s, he needed to have someone close to him explain what he said.

In 1985, he got pneumonia and needed a tracheotomy to preserve his life, which prompted him to use a voice synthesizer, notably the DECtalk voice synthesizer, to assist him speak.

Digital Equipment Corporation created DECtalk, a text-to-speech technique, in 1983. Hawking received a customized version.

Many people remember Hawking’s voice as the synthesized version; nevertheless, footage has appeared online of Hawking giving an interview ‘in the late 1970s’ without the aid of a synthesizer but with the assistance of an interpreter.

The video shows Hawking discussing black hole theory on an old television broadcast, with his remarks repeated by a translator who was one of his students at the time.

In the video, he claims, “You wouldn’t notice anything unusual if you passed through the black hole.

“Once you pass a certain critical point, then you’d never be able to get back again no matter how much rocket power you used.”

People are taking to social media after hearing his voice pre-synthesizer for the first time.

One YouTube user noted, “Stephen Hawking’s body may have been a prison, but his brain was not. He was able to reach not only other people, but also myself, with his brain alone, and not even his limitations could stop him. “Absolute legend.”

“It was nice to finally hear him speak,” another said.

Another said, “Even with this man’s failing speech and the subtitles, you can kinda hear what he’s saying.”

And the topic has spread to X, with one user writing: “I could still hear him clearly without the voice synthesizer.”

“Such a brilliant mind,” another person commented.

A third said, “He’s an inspiration.”
