I am big time user of Amazon’s WhisperSync feature. With that feature I can simultaneously read the book and listen to it.
This is especially helpful when you’re on the go but still want to have a visual now and then or highlight text for later.
The problem is that many books don’t offer that feature. There is a built-in read function now in the kindle app, but it’s crap.
So, if you ask me, I’d prefer a good human-written book with an additional AI voice on top to enable that feature for me.
