I want to know what is the best option to listen to audiobooks while reading the transcript. Is buying the books twice my only recourse? (Audio + Ebook) Is there a service that offers both?

ebooks, epub, IFTTT, pdf, reddit,

I want to be able to listen to the audiobook and follow along with a ebook. I want to know if a service exist or if I have to buy both Ebook and Audiobook on apple books.... The platform doesn't matter but preferably have a phone / tablet version (I work in mobile so have access to many phones and tablets) via /r/ebooks https://ift.tt/WVU4xHj
