It’s highly dependent on what I’m viewing, of course. Some people just… talk… so… slooowly. If the content is interesting then they get 1.5x. Some people talk a mile a minute with dense information and they get 1x. For myself, 2x is usually too fast to be enjoyable.

This is the problem: the settings should let you specify an absolute rate like average words or phonemes per minute.

Maybe some coefficient of word/thought complexity.

Not a relative multiple of the base rate. Garbage in, garbage out and all.

My experience has been that it's not just the cadence of the speaker, it can be their intonation and pitch that determines whether I can speed it up. And some deep voiced person from Essex who is recording in their bathroom ... not a prayer, because I can't find the word boundaries from the background noise
