I asked if anyone could point me to examples of "how fast do screenreaders actually read", a few months ago.[1] The best examples I could find at the time, are here: https://www.youtube.com/watch?v=izrC4R7SsH4#t=1561s and here https://www.youtube.com/watch?v=92pM6hJG6Wo Searching a few days ago, I learned that the average speed that experienced users generally use is 250-400 wpm, and that the default settings are around 180wpm. (Note: Users seem to typically talk about the speed they use in terms of x% of maximum, rather than wpm, e.g. "I've got 63% with rate boost, and rising. I used to think 75% with JAWS was fast, but not anymore. I'm just turning it 1% faster every couple days, and I'm doing it because I can." [2]) https://en.wikipedia.org/wiki/Words_per_minute#Speech_and_listening says English language audio books are generally at 140-160 wpm.
