Why would they when you can just plug any epub into a program and use google tts. Ive listened to about a book a day for the past few years doing this and i love it. Yeah it took getting used too, but once you find an ai voice you like and figure out which words to auto replace to sound right its honestly better then an audiobook. Well at least to me it is, i could never stand when the reader would change their voice for different characters.
This is what I don't get from a business standpoint. Why would anyone buy an AI read audiobook for $20 when they can get the exact same audio by buying the ebook for $0.99 and running it through AI?
