Follow the sentence you hear, lit on the page

Press play and the sentence you hear lights up violet, the page moves with it, and a tap on any sentence jumps the voice there. See how the highlight works and where it stops.

Short answer

Press play and the sentence you hear turns violet on the page. The page scrolls to keep it in view, and a tap on any other sentence moves the voice there. The same sentence shows on your Lock Screen and in the Dynamic Island.

Reading along while you listen keeps your eyes and your ears on the same line. You stop drifting, you catch the names you would mishear, and you can glance down after a phone call and see exactly where the voice is.

Watch the sentence move

Press play on anything on your shelf. The sentence you hear turns violet on a lavender wash, the same color in light and dark mode, and the page scrolls so it stays in view.

The highlight works sentence by sentence:

What you doWhat happens
Press playThe current sentence lights up and the voice starts
Tap another sentenceThe voice jumps there and keeps going
Press back onceThe paragraph starts again
Press back twiceThe paragraph before starts
Press forwardThe next paragraph starts

Keep whole sentences together

A reader that splits sentences at every period stops after "Mr." and starts again at "Bennet". In Aloudeo, titles, initials and abbreviations stay inside their sentence, so "Mr. Bennet", "J. K. Rowling" and "U.S. Army" stay one breath, and the highlight covers the whole sentence.

See it on your Lock Screen

Lock your iPhone and the sentence you hear moves to a card on the Lock Screen and in the Dynamic Island, with play, pause, back and forward. Tap the card to open the page where the voice is.

Where it stops

  • The highlight lights sentences, not single words.
  • On a scanned page, it can only light the text your iPhone recognized.
  • A table or a formula has no sentence to say, so the voice skips it and the highlight moves to the next paragraph.

Questions you ask about this

Does the highlight follow every word?
It follows sentences. Long sentences light up in parts of about 140 characters, so the highlight never covers half a page.
Can I jump back to a sentence I missed?
Tap it. The voice starts from that sentence. The back button starts the paragraph again, and a second press goes to the paragraph before.
Does the highlight work on scanned PDFs?
Yes, once your iPhone has read the text off the page. The highlight lands on the recognized text, so a page with smudges or columns can light up slightly off.
