Character voices
Character Voice TTS for Your Own Books
Most text to speech reads a whole novel in one voice. Lyraboo gives every character their own — automatically, for every book you upload.
From book to full cast
No voice menus, no tagging lines by hand.
The AI finds who is speaking
Lyraboo separates narration from dialogue, works out which character says each line and chooses a voice to suit each of them.
Listen like an audiobook
The first chapter is ready in a minute or two and plays in a familiar music-app-style player while the rest generate.
What “character voice TTS” means
Plain text to speech has one narrator for everything: the description, the hero, the villain, the child. In a chapter that is mostly dialogue, you stop knowing who is talking. Character voice TTS fixes that by giving each speaking character a separate voice, so a conversation sounds like a conversation.
Apps get there in three ways:
- You assign the voices — flexible, but you do the casting for every book.
- A paid add-on — a full-cast mode charged per page on top of a free single voice.
- Automatic for every book — what Lyraboo does: the app reads the book, finds the characters and casts them before you press play.
How Lyraboo casts a book
The text is split into chapters, and narration is separated from speech. Each line of dialogue is attributed to its speaker — including the long back-and-forth stretches where the book stops writing “she said”. Every character then gets a voice chosen to suit them, and keeps it for the rest of the book. Non-fiction, with no characters, is read by one narrator.
More than voices: a player you already know
- Chapters and a progress bar, like any audiobook.
- Playback speed from 0.25× to 3×.
- Background playback with lock-screen controls, and it remembers where you stopped.
- Read along: the text on screen follows the voice, with each speaker labelled.
Limits worth knowing
Voices cannot be hand-picked yet, and attribution can slip in very long unattributed dialogue. English books sound best; Spanish, Portuguese, French, German, Italian and Russian are in beta. Lyraboo is Android-only and needs an internet connection — the voices are generated in the cloud. Want the details of the cast itself? See multi-voice audiobooks.
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 is character voice TTS?
Ordinary text to speech reads everything in one voice. Character voice TTS gives each speaking character their own voice, so you can tell who is talking by ear — the way a full-cast audiobook or an audio drama works.
Do I have to assign the voices myself?
Not in Lyraboo: the casting is automatic for every book. Some apps make you pick a voice per character or charge extra for a full cast; here it is simply how every book is narrated.
Does a character keep the same voice through the book?
Yes. Once a character has a voice, they keep it from chapter to chapter, and new characters get their own as they appear.
Can I choose which voice a character gets?
Not at the moment — voices are cast automatically. That keeps it effortless, at the cost of control.
Is it free?
Free to start: every account gets one hour of listening a month, no card required. More hours come with a subscription.
