What has caused the change in Stephen Hawking's speech pattern?
Stephen Hawking, who passed away in 2018, was one of the world's most renowned theoretical physicists. He was diagnosed with amyotrophic lateral sclerosis (ALS) at the age of 21, and over time, the disease caused the muscles in his body to become paralyzed. This paralysis eventually affected his ability to speak.
Initially, Hawking was able to speak with slurred speech. However, as his condition progressed, he lost the ability to speak altogether. In 1985, he underwent a tracheotomy, which allowed him to breathe through a tube in his throat. This procedure also meant that he could no longer speak.
To communicate, Hawking used a speech synthesizer. This device allowed him to type words on a computer, which were then converted into speech. The speech synthesizer gave Hawking a computerized voice, which became his trademark.
The change in Hawking's speech pattern was a result of his ALS diagnosis. The disease caused the muscles in his body to become paralyzed, including the muscles in his throat. This paralysis made it difficult for him to speak, and eventually, he lost the ability to speak altogether. However, thanks to the speech synthesizer, Hawking was able to continue to communicate with the world.
