I don't think that ai generated voice will replace real humans in audiobooks. Yeah sure the  ai can read a book in a monotone voice that seams real but for it to read something like the LotR it would need to understand the books and imagine how a character would sound like and imitate that. We are still far off from that! Maybe for a book like LotR it would be possible since there is so many reference but there are somany new books coming out that have no references where everything is just purely written.,(reply>), I heard Apple already has something that is really good at using the right tone<br>Edit: Never mind, I didn't finish the video before commenting, that's exactly what the video was about,(reply>), I Can easily imagine a model trained on data specifically for this than can be configured to use different voices for different characters and uses accurate inflection in their voice to mimic emotion in speech though. far is subjective, but I imagine that possibility is closer rather than farther
