You have three ways to hear a PDF on your iPhone. Two come free with iOS and work in any app. The third is a reader app you install. Each one fits a different length of reading, so start with the one that matches your PDF.
Pick the right tool in ten seconds
| You want to | Use | Cost |
|---|---|---|
| Hear one paragraph or a quote | Speak Selection | Free, built into iOS |
| Hear a short PDF once, top to bottom | Speak Screen | Free, built into iOS |
| Get through long PDFs, papers or books over days | A reader app | Depends on the app |
The paths below match iOS 18 and iOS 26. If your Settings look different, search for Spoken Content in the search bar at the top of Settings.
Use Speak Screen for a short PDF
- Open Settings > Accessibility > Spoken Content.
- Turn on Speak Screen.
- Turn on Highlight Content too if you want to follow along. Under it, choose whether you see words, sentences or both lit up.
- Open the PDF in Files, Mail or Books.
- Swipe down from the very top of the screen with two fingers.
A small controller appears with pause, skip back, skip forward and a speed button. Tap the arrow on its edge to shrink it to the side of the screen. You can also ask Siri: say "Speak Screen" while the PDF is open.
Speak Screen reads everything it finds on screen. On a PDF, that means you hear the page number, the running header, the footnote marks and every citation bracket, all in the same tone as the sentences. On a two-page memo you barely notice. On a research paper you hear "open bracket fourteen close bracket" every few lines.
Use Speak Selection for a few lines
- Go back to Settings > Accessibility > Spoken Content.
- Turn on Speak Selection.
- In the PDF, press and hold a word, then drag the handles over the lines you want.
- Tap Speak in the menu above the selection. If you can't see it, tap the arrow at the end of the menu.
Speak Selection fits a paragraph you want to hear twice, a quote you want to check, or a word you can't pronounce. Selecting text page after page on a 40-page report gets tiring fast, so switch tools for anything longer than a page.
Pick a better voice for both
Speak Screen and Speak Selection use the same system voice. The default one sounds flat over long stretches, and you can swap it in a minute:
- Open Settings > Accessibility > Spoken Content > Voices.
- Tap English, then pick a voice.
- Look for voices marked Enhanced or Premium, and tap the download button next to one.
- Go back one screen and drag Speaking Rate to the speed you like.
Download the voice on Wi-Fi. Once it sits on your phone, Speak Screen works in Airplane Mode with it.
Use a reader app for long PDFs
For a report, a paper or a book, you want three things the built-in tools leave out: a voice free of page clutter, your place kept in every file, and listening with the phone in your pocket. You get all three in a reader app. In Aloudeo:
- In Files, Mail or Safari, tap Share and pick Aloudeo. Or open the app, tap + and choose Import files and books.
- Find the PDF in your Papers or Documents folder.
- Press play.
Here is what you get:
- Page numbers, running headers, footnote marks and citation brackets stay off the voice. The page you see keeps them all. See how the speech cleanup works.
- The sentence you hear lights up on the page, and a tap on any sentence starts the voice there.
- Every PDF keeps its place, and your shelf shows how long each one takes at your speed.
- You pick from 14 English voices, plus voices in Spanish, French, Japanese and Mandarin.
- You hear a voice that runs on your phone, so you keep listening offline and with the screen locked. Read more on listening offline.
Scanned PDFs work too: your iPhone reads the text off each page image first, on the phone. See the full PDF format page for what reads well and what trips it up.
Work through a real example: a 40-page report
Say your manager sends a 40-page quarterly report as a PDF, with about 500 words a page. That's 20,000 words.
With Speak Screen, you open it in Files and swipe down. You hear the cover page, then "Page 2 of 40, Quarterly Review, Confidential" at the top of every page. Your bus arrives, you close Files to check a message, and when you come back you swipe down and start from the top of whatever page sits on screen. You scroll to find your spot.
With a reader app, you share the PDF once. You press play, hear the text without the headers, lock your phone and put it away. After the bus ride you open the app and press play again at the same sentence.
How long it takes, at about 165 words a minute:
| Speed | Time for 20,000 words |
|---|---|
| 1x | about 2 hours |
| 1.5x | about 1 hour 20 minutes |
| 2x | about 1 hour |
Run your own numbers in the listening time calculator. If you read papers like this every week, the study papers guide shows how to work through a stack of them by ear.
Weigh the trade-offs
Every option costs you something. Here is the honest version:
- Speak Screen costs nothing and works in every app on your phone. You pay with your attention: you hear every page number, and you find your place by hand each time.
- Speak Selection gives you the most control over what you hear. You pay with your thumbs: it suits a paragraph, never a chapter.
- A reader app: you get clean listening and your place in every file. You pay with money and one extra step. In Aloudeo, the free plan gives you 15 minutes of listening a day at speeds from 0.75x up to 2x. Pro goes up to 3x and costs $4.99 a week, $39.99 a year with a 7-day free trial, or $79.99 once for lifetime use.
If you hear one short PDF a month, stay with Speak Screen. If PDFs pile up on your phone faster than you get to them, you win back the time you spend scrolling for your place. The side-by-side comparison goes row by row.
Fix the usual problems
Nothing happens when you swipe down. Start the swipe at the very top edge with two fingers together. A swipe that starts lower opens the search or scrolls the page. Check that Speak Screen sits on in Settings > Accessibility > Spoken Content.
You hear nothing on a scanned PDF. Press and hold a word on the page. If you can't select any text, the PDF holds pictures of pages, and the built-in tools find nothing to read. Share it to a reader app with text recognition, or scan the paper pages yourself.
The words come out in the wrong order. PDFs with two columns, sidebars or boxes confuse any reader. Zoom so one column fills the screen before you swipe down, or use Speak Selection on one column at a time.
The voice sounds robotic. Download an Enhanced or Premium voice, as shown above. The default compact voices take less space and sound flatter.
You lose your place every time. Speak Screen keeps no bookmark. Note the page number before you close the PDF, or move long reading into an app that keeps your place for you.
