Most of the books identified as “Apple Books audiobook narrated by a digital voice based on a human narrator” seem to be romance fiction. From what I’ve read about the genre, romance novels are written in huge quantities based on standard story, character, and situation templates, and enthusiastic fans often read dozens or hundreds of the books a year. Romance-fiction audiobooks would therefore seem to be a prime target for good-enough AI production. Presumably the stories themselves will be next.
I used to use the Kindle's text to speech feature before they removed the speaker, while driving or doing dishes, and that was just the standard robotic voice. This is fantastic, though I agree with another comment that buying it for the normal price is a bit odd.
