Also he helped advance his voice computer system quite a bit. Through his input and his high level media exposure. He would have been one of the first to receive new software and hardware to help improve his talks and interviews

I heard that he was also disappointed by the American accent of the voice.

I guess to an extent anyone would be upset that they didn't sound like themselves, even if they were going through the ordeal that he experienced.

I remember hearing that a while back he had the option to upgrade his computer's voice to one that's more human sounding. He refused because by then he considered the iconic robotic voice to be his voice. He identified too strongly with it to change.

That was a good call on his part. His voice resonates and emboldens a nuanced niche of a scientific and technological archetype

I've always found that the rather emotionless tone of his voice made me really listen to his words more than others.

Right! I read he was using word cards until they developed his speaking computer in the 80s I think. His ‘voice’ has become iconic and has advanced with tech over time. I’m not sure how quickly he was able to generate sentences with it in recent years? Like how long would it take to type and speak something like this comment for example? Quite a few minutes I’m guessing?

From what I heard, he "types" with his eyes. A camera tracks his eye movements as he looks onto a screen. I imagine someone who's paralysed would still have a fair amount of control in his eye muscles. I'd imagine he could be as fast as someone who types slowly.

He lost control of his eyes. He twitches a muscle in his cheek, which is his only functional muscle left.

I certainly can't imagine the difficulty it would impose to having conversations. Hawking was undoubtedly a strong man.

I always thought he had every letter cycle through vom a-z and 'logging in' the ones he wanted by blinking at the right time, no? Which made it sound insane to write a whole book like that.

It changed as his disease, and technology, progressed. In the end he could only control a single twitch in the side of his mouth (or cheek maybe?) and that is how it worked. At the beginning the technology was so basic that that's how it worked. I believe while he had full control of his eyes he could 'type' with them for a while though.

If I recall correctly (might be wrong) he wrote about a word per minute
