Turn the reading list into something you can listen to on the bus, at the gym or with tired eyes — chapter by chapter, at your own speed, and with a different voice for every character in set novels and plays.
Works best for prose-heavy material.
A text-based PDF, an EPUB or a TXT file. If you can select a sentence in the PDF, it will work.
Non-fiction is read by one clear narrator; set novels and plays get a voice for each character.
Speed from 0.25× to 3×, background playback, and the text on screen follows the voice when you want to look.
Maths and science textbooks full of equations, tables and diagrams. Those are read as text, or skipped where there is no text at all, so listening is a companion to the page there, not a replacement. Scanned PDFs without a text layer cannot be narrated.
Hearing the material frees your eyes and adds study time you would not otherwise have — the commute, the walk, the queue. Following the text on screen while it reads helps some people concentrate, and for readers with dyslexia it can make long reading manageable; see listening instead of reading.
The things people notice in the first chapter — and the reasons they stay.
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.
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.
Chapters, speed from 0.25× to 3×, background playback with lock-screen controls, and it picks up exactly where you stopped.
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.
Novels, fanfiction and web-serial exports, indie ebooks, study PDFs — plus over 1,000 English classics already in the app.
One free hour of listening every month, no card needed. Hours are spent once per chapter — replaying is always free.
If you have it as a DRM-free, text-based PDF or EPUB, yes. Textbooks bought through platforms that lock the file (DRM) cannot be imported.
Not well, honestly. Narration works best on prose. Equations, tables and dense footnotes are read as text, which can sound awkward — keep the PDF open for those parts. For research papers full of them, Paper2Audio, which summarises tables and skips references, is the better tool.
That is where it shines: set novels and plays get a full cast, with a different voice for every character, so dialogue is easy to follow.
One hour a month, without a card. A subscription adds more hours; each chapter costs hours once, and replaying it for revision is free.
Upload a book you own and let the app turn it into a multi-voice audiobook automatically.
