About the app
Lyraboo is an Android app that turns books you already own — EPUB, PDF or TXT — into audiobooks with a full cast: every character in the story gets their own AI voice.
You upload a book from your phone. Lyraboo splits it into chapters, separates the narration from the dialogue, works out who is speaking and casts a voice for each character. The first chapter is ready in about one to two minutes, and the rest generate in the background while you listen in the built-in player — with chapters, playback speed, lock-screen controls and on-screen text that follows the voice.
It is made for fiction, where a single text-to-speech voice makes long dialogue hard to follow: novels, fanfiction from AO3, web serials from Royal Road, and indie or older books that will never get an official audiobook.

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.
Free to start. Every account gets one hour of listening a month, renewed monthly, with no card required. More hours come with a Weekly, Monthly or Pro subscription. Hours are spent once, when a chapter is first generated; replaying is free.
Most read a book in one voice. Lyraboo separates narration from dialogue, detects the characters and gives each one a distinct voice automatically, so a novel sounds like a full-cast audiobook. It is built for listening to books, with chapters and a proper player, rather than for reading documents aloud.
No. Lyraboo needs an internet connection and plays audio inside the app. If you need an MP3 file, an online converter is the better tool; if you need offline listening, apps that generate speech on the phone, like AudiFlo or Éist, do that.
Scanned PDFs without a text layer cannot be narrated, and DRM-protected ebooks cannot be imported. A text-based PDF, a DRM-free EPUB or a TXT file works.
Not yet — Lyraboo is Android-only for now.
Upload a book you own and let the app turn it into a multi-voice audiobook automatically.
