Check the PDF has real text
Open it and try to select a sentence. If the text highlights, any app can read it. If it does not, it is a scan — a picture of pages — and needs OCR first.

How to Turn a PDF into an Audiobook
Any PDF with real text can become an audiobook you listen to on your phone — and a novel can get a different AI voice for every character. Here is how, with the free and paid options.
Three steps on Android
From a PDF on your phone to a playing audiobook in a couple of minutes.
Upload it to an audiobook app
In Lyraboo, tap + and pick the PDF. The app splits it into chapters, finds the dialogue and gives every character their own voice — nothing to configure.
Press play
The first chapter is ready in about one to two minutes; the rest generate while you listen. Change speed, lock the screen, pick up where you stopped.
First decide what kind of audio you want
- A file to copy somewhere — an online PDF-to-MP3 converter, NaturalReader’s app or @Voice Aloud Reader. One voice, no player.
- A document read to you — Speechify, ElevenReader, NaturalReader, or Paper2Audio for academic papers. Natural voices, one voice for everything.
- A book you listen to like an audiobook — Lyraboo: chapters, a real player, and every character in their own voice.
Not sure which? The tools are compared in PDF to speech converters and, for books, in the best apps to turn a PDF into an audiobook.
Why a novel needs more than one voice
Read in one voice, a novel loses the thing that makes it a story: you can no longer hear who is speaking. In a long conversation with no “she said”, a single narrator leaves you counting lines to keep track. Lyraboo casts the book instead — a narrator for the description and a distinct AI voice for every character, kept for the whole book — so dialogue sounds like a scene and a 400-page PDF is as easy to follow as a full-cast audiobook. Non-fiction simply reads in the narrator’s voice.
The rest works like a music app: chapters, 0.25×–3× speed, background playback with lock-screen controls, and the text scrolling under the player like song lyrics, words lighting up as they are spoken and each line labelled with its speaker. Tap any word to jump there.
Fixing PDFs that sound wrong
- Scanned pages. No text, nothing to read. Run the PDF through OCR first, or use Speechify’s or NaturalReader’s scanner. A digital edition of the book is usually cleaner than any scan.
- Headers, footers, page numbers. Repeated on every page as text. An EPUB of the same book avoids them — see EPUB to audiobook.
- Two columns, tables, footnotes. Typical of papers and textbooks. Paper2Audio is built for these (see Paper2Audio and Lyraboo compared); for course material in Lyraboo, see listening to textbooks and study PDFs.
- DRM. A protected store book opens only in the store’s app. DRM-free PDFs — from indie authors, public-domain libraries, or DRM-free Kindle downloads — work.
What it costs
Lyraboo is free to start: one hour of listening every month, no card. Subscriptions add hours — in the US the Monthly plan is $9.99 — and a chapter costs hours only once; replaying it is free. It needs an internet connection and works on Android. More about the app: PDF to audiobook app for Android.
Why listeners choose Lyraboo
The things people notice in the first chapter — and the reasons they stay.
Every character gets their own voice
Lyraboo’s AI finds every character in the book and casts a distinct voice for each — automatically, for every book. You always know who is speaking, and dialogue sounds like a real conversation instead of one narrator doing all the parts. Most reading and text-to-speech apps use one voice for everything.
The text follows along, like lyrics
Under the player, the book scrolls with the voice the way song lyrics do in Spotify: words light up as they are spoken, each line shows who says it, and tapping any word jumps there.
A player that feels like a music app
Chapters, speed from 0.25× to 3×, background playback with lock-screen controls, and it picks up exactly where you stopped.
Upload, and you are listening in minutes
Pick an EPUB, PDF or TXT and there is nothing to set up: the first chapter is ready in about one to two minutes, and the rest generate while you listen.
Any book you have, not just a catalogue
Novels, fanfiction and web-serial exports, indie ebooks, study PDFs — plus over 1,000 English classics already in the app.
Fair on cost
One free hour of listening every month, no card needed. Hours are spent once per chapter — replaying is always free.
Frequently Asked Questions
Can I turn a PDF into an audiobook for free?
Yes. On a computer, Microsoft Edge reads PDFs aloud for free. On Android, ebook readers like ReadEra, Moon+ Reader and Librera read them with the phone’s voice, and @Voice Aloud Reader is free with ads. For natural AI voices, Paper2Audio gives 56 free hours a week, ElevenReader 10 hours a month, and Lyraboo one hour a month of full-cast narration with no card.
How long does it take to turn a PDF into an audiobook?
In Lyraboo about one to two minutes until the first chapter plays; the rest of the book generates in the background while you listen, so you do not wait for the whole PDF.
Can I get the audiobook as an MP3 file?
Not from Lyraboo — the audiobook plays inside the app. NaturalReader’s mobile app can export MP3, and @Voice Aloud Reader records MP3, OGG or WAV, in a single voice.
Why does my PDF audiobook read page numbers and headers?
PDFs repeat the header, footer and page number on every page as ordinary text, and simple text-to-speech reads all of it. Use an app that strips them, or an EPUB of the same book if you have one — EPUBs have no pages to repeat.
Can I do this on iPhone?
Lyraboo is Android-only for now. On iPhone, ElevenReader, Speechify, Paper2Audio, NaturalReader and Voice Dream Reader read PDFs aloud, each in one voice.
Is it legal to make an audiobook from a PDF?
For your own listening, from a file you own, apps like these are the digital version of having a book read to you. Do not share or sell audio made from someone else’s book.
