I assumed it was a computer voice. Does anyone have an example of an on-camera human speaking that way? I think it'd be very off-putting to hear someone speak to me like that in person.

I've definitely heard intonation like this from before computer voices were of this quality. I don't know if I've seen an on-camera human speaking this way because it's often narrators or English dubs of Japanese content.

I hate that voice so much. So many videos that are just a vapid TTS reading some ChatGPT-esque summary with some stock footage but you only find out that's what it is after the unskippable advert.
