How did Stephen Hawking lose his voice?

Answer 1

Stephen Hawking has ALS (amyotrophic lateral sclerosis), which causes almost complete paralysis of his muscles, including his larynx. He also had to undergo an emergency tracheotomy due to pneumonia, which damaged his ability to speak even further.

Answer 2

As of 14/03/2018 - Stephen Hawking aged 76. He died peacefully at his home in Cambridge in the early hours of Wednesday. It is reported that his passing was of natural causes associated with Motor Neurone Disease

Answer 3

During a visit to the research centre CERN in Geneva in 1985, Hawking contracted pneumonia, which in his condition was life-threatening as it further restricted his already limited respiratory capacity. He had an emergency tracheotomy, and as a result lost what remained of his ability to speak. He has since used an electronic voice synthesizer to communicate.

Answer 4

Stephen Hawking lost his voice due to a tracheotomy performed after a severe case of pneumonia. This caused damage to his vocal cords, leading him to rely on a computerized speech synthesizer to communicate.

Answer 5

Hawking has a disease related to ALS, which has progressed over the years. He is almost entirely paralysed and communicates through a speech machine.
