But I also see some positives for the narrative voice field, but at the expense of actual actors.
The latest sequel to a favorite audio book series has the professional narrator pronouncing different character names and town names entirely different than the previous 7 books.
In another book the narrator completely changed the character voices in the sequel compared to the first.
The positives for listeners is eventually we can guarantee that voices are completely consistent between narrations. An editor will soon be able to describe the emotions of a character and nuance how the AI performs certain scenes.
It's really sad but I think the end of human audio storytelling is coming to and end quite rapidly.
