How to Read a PDF Aloud on iPhone

Your iPhone can already read a PDF out loud: open the file in Files or Apple Books, turn on Speak Screen, and swipe down with two fingers. That works well for a few pages. For long documents, reports or textbooks, a dedicated PDF reader aloud app is more comfortable, and below you'll find both approaches step by step.

The built-in way: Speak Screen

Speak Screen is part of iOS accessibility features and costs nothing. It reads whatever is currently on your screen, including an open PDF.

Turn it on once

1. Open Settings → Accessibility → Spoken Content.
2. Turn on Speak Screen.
3. Optionally turn on Highlight Content so words or sentences are highlighted as they are spoken (in supported apps).
4. Tap Voices to download a better voice for your language. Some voices are large downloads, so use Wi‑Fi.

Read a PDF with it

1. Open the PDF in the Files app, or add it to Apple Books (share the file and choose Books).
2. Scroll to where you want to start.
3. Swipe down with two fingers from the top of the screen, or ask Siri "Speak screen".
4. A small controller appears with play/pause and speed controls.

In Apple Books, Speak Screen turns pages as it reads, which makes Books the better of the two for longer PDFs. If you only need one paragraph, turn on Speak Selection in the same menu, select the text and tap Speak.

Where the built-in method falls short with PDFs

Speak Screen is a general tool, not a PDF reader, and PDFs expose its limits more than web pages do:

• It reads everything on the page. Running headers, footers, page numbers, footnote markers and figure captions all get spoken, often in the middle of a sentence.
• Columns can get mixed up. In two-column papers and magazine layouts, the reading order isn't always the order you'd read in.
• It's built for short sessions. If you switch apps, take a call or close the document, you start again by finding your place and swiping down.
• No saved position. It doesn't remember where you stopped in each document, so returning to a 200-page PDF tomorrow means scrolling to find your page.
• Standard system voices. The downloaded voices are clear, but they're the same system voices used everywhere in iOS.

For a quick look at a short PDF, none of this matters much. For a long read you want to listen to over several days, it adds up.

Reading a PDF aloud in Aloudy, step by step

Aloudy is an iPhone and iPad app (iOS 18 or later) that reads documents aloud with neural voices running on your device. PDFs open in their original layout, and the sentence being spoken is highlighted right on the page.

1. Import the PDF

• From Aloudy: tap import and pick the file from Files (iCloud Drive, On My iPhone, or any connected storage).
• From another app: open the PDF in Mail, Files, Safari or a messenger, tap Share, and choose Aloudy.

2. Press play and follow along

The page looks exactly like the PDF. As it reads, the current sentence and word are highlighted, so you can look away and find your place again at a glance. Tap any sentence to jump to it or hear it again.

3. Navigate a long document

For PDFs that have one, open the table of contents to jump straight to a chapter or section. You can also search inside the document for a word or phrase.

4. Set the speed and voice

Choose a speed from 0.75× to 2×. Many people start at 1× and speed up as they get used to a voice. There are 46 neural voices in 32 languages.

5. Listen in the background, and come back later

Playback continues with the screen locked, with controls on the lock screen and in Control Center, and it keeps going after a phone call. When you reopen the PDF, the app resumes where you stopped, separately for each document.

6. Listen offline

Voices run on the device, so after a one-time voice download (the multilingual voice is about 140 MB) you can listen in airplane mode, on a flight or on the subway. Your documents never leave your phone, and there's no account to create. More on that in offline text to speech.

A note on the free plan

The free plan includes 5 voices and notes of up to 500 characters, which is enough to try the voices and the reading view. A full PDF is longer than that, so reading whole documents needs Aloudy Pro: unlimited text and all 46 voices, available monthly or as a one-time lifetime purchase.

Built-in vs. an app: which to use

	Speak Screen (built in)	Aloudy
Price	Free	Free to try; Pro for long PDFs
Original PDF layout	Yes, reads what's on screen	Yes, with the spoken sentence highlighted
Remembers your place	No	Yes, per document
Table of contents and search	Depends on the app you read in	Yes
Offline	Yes, with downloaded voices	Yes, after one voice download
Voices	Standard system voices	46 neural voices, 32 languages

If you read the occasional short PDF, stick with Speak Screen. If you listen to long PDFs regularly, an app saves you the repeated setup.

Tips for scanned PDFs

Some PDFs are just pictures of pages: you can't select the text, and search finds nothing. Text-to-speech needs real text, so a scan has to be recognized first.

• Check first. Press and hold on a word in the PDF. If you can't select it, it's a scan.
• Use Live Text for short passages. Take a photo or screenshot of the page, open it in Photos, select the text, and tap Speak (with Speak Selection turned on).
• Scan pages in Aloudy. The app recognizes text in scanned pages and photos of printed pages on the device, then reads it aloud with the same highlighting. See how to scan a page and read it aloud.
• Get a good image. Flat pages, even light and a straight angle make recognition noticeably more accurate. Glare and curved book spines cause most errors.

More ways to listen

If you'd rather keep the result as a long listen, read how to turn a PDF into an audiobook. For everything else your iPhone can read aloud, see the guides.

The app was made for exactly this kind of reading: open a PDF, see the page as it was designed, and listen with the current sentence highlighted, offline and privately. If Speak Screen covers what you need, that's great. If you keep coming back to long PDFs, try Aloudy and see whether it fits the way you read.

FAQ

Can iPhone read a PDF out loud without an app?

Yes. Turn on Speak Screen in Settings → Accessibility → Spoken Content, open the PDF in Files or Apple Books, and swipe down with two fingers from the top of the screen. In Apple Books it turns pages as it reads.

Why does my iPhone read page numbers and headers in a PDF?

Speak Screen reads everything visible on the screen, and in a PDF that includes headers, footers and page numbers. A PDF reader aloud app that highlights the spoken sentence on the page makes it easier to follow the actual text.

Can I listen to a PDF offline?

Yes. Speak Screen works offline once a voice is downloaded. In Aloudy, voices run on the device, so after a one-time voice download you can listen in airplane mode.

Can Aloudy read a whole PDF for free?

The free plan is for trying the app: 5 voices and up to 500 characters per note. Reading a whole PDF needs Aloudy Pro, which is available monthly or as a one-time lifetime purchase.
