AI reads the book
It splits the text into chapters and tells narration apart from dialogue — the structure a human narrator would mark up first.
AI narration
AI Audiobook App for Your Own Books
Upload a book you own and AI turns it into an audiobook — with chapters, a proper player and a different voice for every character.
Three things the AI does
The same steps a production team takes, done in minutes.
AI casts the characters
Every line of dialogue is attributed to a speaker, and each character gets a voice chosen to suit them.
AI voices perform it
Natural AI voices narrate chapter by chapter. The first is ready in a minute or two; the rest follow while you listen.
Listening, not producing
“AI audiobook” covers two different products. Some tools help authors produce an audiobook to sell: you edit pronunciation, tweak every line and export files. Lyraboo is the other kind — an app for listeners. You bring a book you want to hear, and a few minutes later you are listening to it. There is nothing to edit, and nothing to export.
What makes it sound like an audiobook
- A full cast. Each character has a distinct voice, so dialogue is easy to follow.
- A real player. Chapters, speed from 0.25× to 3×, lock-screen controls, resume where you stopped.
- Read along. The text follows the voice on screen when you want to look.
- Your files. EPUB, PDF and TXT — plus a built-in library of over 1,000 English classics.
What it costs, and why
High-quality AI voices cost real money to generate, so no honest service can offer unlimited free conversion. Lyraboo gives every account a free hour each month and spends hours only once, when a chapter is first narrated; listening again is always free. More on the mechanics in what is Lyraboo.
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
What does an AI audiobook app do?
It turns written text into narrated audio with AI voices. The good ones also handle the book’s structure — chapters, narration versus dialogue — and Lyraboo goes one step further by casting a separate voice for each character.
Can I sell or publish the audiobook Lyraboo makes?
No. Lyraboo is for listening to books you own, inside the app; it does not export audio files. Authors who want an audiobook to sell need a production tool or a narrator and a distributor.
How much does it cost?
Every account gets one hour of listening a month free, without a card. Subscriptions add more hours; in the US the Monthly plan is $9.99. Hours are spent once per chapter — replaying is free.
Which languages can the AI narrate?
English sounds best. Spanish, Portuguese, French, German, Italian and Russian are in beta, and the app detects the book’s language by itself.
