How to Listen to a PDF on iPhone: Every Method, Compared

The four methods at a glance

Method 1: A PDF reading app (the full solution)

A reader app imports the PDF as a document rather than reading the screen, so it can rebuild paragraphs across page breaks, drop page furniture, remember your place and keep going with the screen off. Here’s the flow in ReadSong:

1. Tap import and pick the PDF from Files, or use Share → ReadSong from Mail, Safari or another app.
2. ReadSong extracts the text, removes running headers and page numbers, rebuilds paragraphs, and keeps the PDF’s bookmarks as a table of contents.
3. If the PDF is a scan, it recognizes the text on the phone with Apple’s Vision OCR first.
4. Pick a voice and press play. The current sentence and word are highlighted, and you can tap any sentence to start from there.
5. Lock the phone and keep listening; the lock screen controls work, and a sleep timer can stop at the end of a chapter.

The voices are neural models rather than the classic system voices. English, Spanish and French are built into the app, and 32 reading languages are available in total. Nothing is uploaded, there’s no account, and once the voices are on the phone it works in airplane mode. Your place is saved per document, and the speed goes from 0.75× to 2×.

The free plan gives you 3 minutes of listening a day with every voice, which is enough to judge the voices on your own PDF but not to get through a whole one; ReadSong Pro removes the limit.

Method 2: Speak Screen (free, built in)

Speak Screen reads whatever is on the screen, top to bottom, in Files, Apple Books, Safari and most other apps that show a PDF.

1. Open Settings → Accessibility → Spoken Content and switch on Speak Screen.
2. Optional: under Voices, download an Enhanced or Premium voice for your language. They sound noticeably better than the default and work offline.
3. Open your PDF and scroll to where you want to start.
4. Swipe down from the top of the screen with two fingers, or ask Siri to “Speak Screen”.
5. Use the small controller that appears to pause, skip or change the speed (the tortoise and hare buttons).

Good for: a few pages or a letter, right now, with nothing to install.

The catches: Speak Screen reads everything it sees, so running headers, page numbers, footnote markers and figure captions all get spoken. On a long report that becomes tiring fast. It reads what’s on screen, so it can stop when the phone locks or at the end of a page, and it won’t remember where you stopped yesterday. That’s the gap a reader app like ReadSong fills: it reads the file, not the screen.

Method 3: Speak Selection (free, more control)

Speak Selection reads only the text you highlight, which helps when you want one section rather than a whole page.

1. In Settings → Accessibility → Spoken Content, turn on Speak Selection.
2. In the PDF, press and hold a word, then drag the handles to cover the passage.
3. Tap Speak in the menu that pops up (you may need to tap the arrow to find it).

Good for: a single paragraph or definition.

The catches: you select by hand, page by page, and some PDFs don’t let you select text at all (more on that below).

Method 4: Copy the text somewhere else

PDF text rarely copies cleanly: line breaks land mid-sentence and hyphenated words split in two. Fine for a short article, not for a book.

Which method should you use?

• A long report, paper or ebook: a reader app such as ReadSong.
• A scanned PDF: a reader app with OCR. The built-in tools need real text to read. See how to listen to a scanned PDF.
• One or two pages, today: Speak Screen. Nothing to install.
• A specific passage: Speak Selection.
• You want an audio file to keep: ReadSong Pro can export one. See converting a PDF to an audio file.

How long will it take to listen to my PDF?

At normal speed, speech runs at roughly 150 to 160 words a minute, and a typical page of text holds 250 to 300 words. So a page takes about two minutes at 1×, and a 300-page PDF lands around 8 to 10 hours. At 1.5× that drops to five or six hours; at 2×, four or five.

When the PDF won’t read at all

If Speak Screen goes silent or reads gibberish, the PDF probably holds pictures of pages rather than text. Try to select a word: if nothing highlights, there’s no text to read. Our guide to why your iPhone won’t read a PDF aloud goes through seven causes and fixes, and if the problem is headers and footnotes rather than silence, see skipping headers, page numbers and footnotes.

FAQ

Can my iPhone read a PDF aloud for free?

Yes. Speak Screen and Speak Selection are built into iOS and cost nothing. Turn them on under Settings → Accessibility → Spoken Content.

Does Speak Screen work offline?

Yes, once you’ve downloaded a voice. Enhanced and Premium voices are downloaded once in Spoken Content settings and then work without a connection.

Will a PDF keep reading when I lock my iPhone?

Speak Screen reads what’s on screen, so it can stop when the phone locks or at the end of a page; don’t count on it either way. ReadSong keeps reading with the screen locked and shows controls on the lock screen.

Why does my iPhone read the page numbers?

Speak Screen reads everything visible on the page, including headers, footers and page numbers. A reader app that rebuilds the text, rather than reading the screen, can drop them, as ReadSong does on import.
