The big thing that's missing so far is performance. Voice-cloned stuff I've heard is pretty flat. A real voice-over artist/reader will put in dramatic pauses, will create both distinct and subtle emphasis on words, and vary the speed of their reading given the tension of the scene. Voice overs dont' just sit in chair, they perform. They'll smile, and you can hear it; they will frown or scowl that that'll come through the voice; they'll gesticulate with their hands. All these things animates the voice, imbues it with feeling and resonance and character. AI is not there yet, and I'm struggling to imagine that they will be able to do this without making some kind of error that'll just take you right out of the story.
