My dog fell asleep while I had episode 4 running (the end caught me by surprise, haha).
I mean, she would have fallen asleep anyway, I probably could not. The voice is a little unpleasant and I concentrate too much on the nonsensical stories. But I also can't really fall asleep when the TV is running, so YMMV.
It is kind of hard to sleep to, I agree. This is a deepfake voice, ie it's generated by Google's WaveNet, which afaik is a deep learning thing. Unfortunately they didn't have a more whispered/softer voice, but I like the insanity of the generated stories anyway.
GPT3 does tend to get a bit repetitive, though, with the default temperature (0.7).
ASMR is not about whispering, but about pleasant sounds that make you feel nice and tingly. Most people may react well for whispering in particular, making it very popular in ASMR videos, but that doesn't mean all of them do - others may need a different trigger.
Maybe using some sort of deepfake for voice would make this a 100x better.
