Idk how much experience you have with this type of thing, but when I listen to my books i use my imagination to picture and hear things the way i want just like when i read a book normally. Ive read well over a 1000 books doing so, and that doesnt count rereads, and having the ability and willingness to use this method has drastically increased the amount i read but also my enjoyment doing so. The app i use also allows me to edit words and phrases throughput the book where i can correct how things are pronounced. Hell there's a series that has this stupid catchphrase that i completely removed from all 20 books cause it was annoying. Im sure im only a single person that likes this method, but if i can find it enjoyable then when real ai gets put to work it'll capture others.
