That's really interesting. Basically the audiobook is more of an interpretation of the text. It's perhaps closer to a movie adaptation. Once you lose the exception for the TTS to "tell you a story" but rather to "tell you the words", it becomes just a different input stream. I didn't think about it like that until now. I'll give it a try.

I listen to a lot of non-fiction in TTS but I haven't found it all that satisfactory for novels. Although part of the reason is if I'm listening to a novel via TTS it's because there isn't an audiobook available and I've had to do some hacky OCR to get the text in the first place.

I do this as well. I used Samsung's TTS engine at first, but Google's has mostly caught up. As a bonus, I can switch between listening (in the car or working out) and reading (most other times) without losing my place.
