I think Amazon calls it Whispersync where you get the Audible narration book and the same book in the ebook Kindle version. Then the narrator reads it to you as the Kindle highlights the words.
I cannot find Spanish versions of books that have this option. Anyone have any? I'd really like to give it a try for a fun way to learn.

Also, ChatGPT said Harry Potter books had this and I see they have the kindle and the audible version, but no indication they would do the sync feature.

Any help would be awesome
