He has ALS
Stephen Hawking used a speech-generating device to communicate, as he had amyotrophic lateral sclerosis (ALS) which left him unable to speak. He used a device that detected tiny movements in his cheeks to select words and phrases from a computer screen. Hawking's communication device allowed him to continue his groundbreaking work in theoretical physics and to communicate with others.
Stephen Hawking underwent a tracheotomy in 1985 after contracting pneumonia. It left him unable to speak without a voice synthesizer, but he continued his research and writing.
Professor Stephen Hawking is unable to walk, due to the effects of ALS (Lou Gehrig's disease) a motor neuron disease which requires him to remain confined to a wheelchair.
The definition of a cyborg is: A fictional or hypothetical person whose physical abilities become superhuman by mechanical elements built into the body. Stephen Hawking is not a cyborg. He has no superhuman abilities. He suffers from ALS, Amyotrophic Lateral Sclerosis, also known as Lou Gehrig's disease, a progressive disease of the nerve cells that control voluntary muscle movement. The disease has made him unable to speak, so he uses an electronic voice synthesizer to communicate. His intelligence is unaffected by his disease.
Stephen Hawking became increasingly paralyzed and confined to a wheelchair over 5 decades, beginning around age 21 when he was diagnosed with a progressive motor neuron disorder similar to ALS (Lou Gehrig's disease).

Stephen Hawking was diagnosed with ALS at the age of 21. The disease made him partly paralyzed and he had to be in a wheelchair. He could barely move and it became worse after time. Doctors said he had only 2 years to live, but he has now lived to the age of 70.
Amyotrophic lateral sclerosis causes complete loss of control over muscles, leaving people unable to adjust their bodies so as to stay upright.
"Without speech" typically means unable to communicate verbally. It could refer to a temporary condition, such as being speechless due to shock, or a permanent state, such as being mute.
It is not accurate to say that "dumb" people are unable to speak. People may have difficulty speaking due to various reasons such as speech disorders, physical disabilities, or language barriers. Intelligence is not the sole determining factor in someone's ability to communicate verbally.
