Audible has thousands of books available "for free" with their membership that are all AI generated. I was the same in the start, but after listening to a few, it really comes down to the voice used. I spent 8h on a plane listening to 1 book, and there was maybe 5 occasions where i had an issue with the voice; and i think all where just "AI weirdness", similar to chat LLMs messing up simple sentence structure or image generating LLMs adding an extra finger.
The one I tried, had a lot of issues. It was a music theory book and it did not know how to pronounce C# (it kept saying C 'hash'). It also referred to, but did not read out the diagrams, or tables.
So, it was not just the voice, but the quality control pipeline that was missing as well.
Maybe it mostly works for old plain text books, but if nobody is checking.....
