Reading along with the narration

How the sentence highlight follows the audio, how to start the narrator anywhere, and what to do when the two drift apart.

What the highlight does

Readuet times every sentence of the book against the audiobook — start, end, and a confidence score. The sentence being narrated is the sentence that is lit, and the page turns itself as the narrator moves on.

A book open in read-along, with the sentence being narrated highlighted.
The lit sentence is the one you are hearing.

Press play and read. There is nothing to keep in step by hand, and nothing to scrub back to when your attention wanders.

Start the narration anywhere

You are not stuck with where the audio happens to be.

Come back to a book after a break and Readuet rewinds a little before resuming — a few seconds after a short pause, closer to half a minute after a day away.

“Syncing this part…”

A book does not have to be fully timed before you can read it. About thirty seconds after you add one, the opening is ready and the rest keeps lining up behind you.

If you jump a long way ahead, you may land somewhere that has not been timed yet and see Syncing this part…. Wait a moment and it resolves itself. Couldn't sync this part means the attempt failed rather than that it is impossible — playing from there again asks for it again.

When the highlight drifts

The highlight is only as good as the pairing between the text and the audio. If they slide apart and stay apart, the two files are usually not the same edition:

Readuet absorbs the ordinary mismatches — front matter, a publisher blurb, a narrator's introduction, a spoken “Chapter One” where the page has none. It cannot absorb a book that is genuinely a different book.

This is worth checking before you upload: an audiobook that is not the same edition as the ebook will never line up, however long you leave it processing.

Which plans include it

The text, the audio and your synced position are on every plan. The moving sentence highlight on your own uploads is part of Duet — books from Discover are timed once and shared, so their read-along is free for everybody.
