Multi-Voice Audiobook
Cast a distinct voice for the narrator and every character in your book. The analysis detects who is speaking; you pick the voices and generate.

From TikTok to podcasts — here's where creators use this tool most.

About this tool
Everything you need to know about Multi-Voice Audiobook
A multi-voice audiobook assigns a distinct voice to the narrator and to each named character, so dialogue reads as a cast instead of one performer switching cadence between lines. The analysis pass reads your manuscript, works out who is speaking on every line, and streams in a chapter-by-chapter cast list — you pick a voice per character from the library or a clone before generating the book.

FAQ
Multi-Voice Audiobook — FAQ
Common questions users ask about the Multi-Voice Audiobook voice. If you need additional help, please contact us via the contact form or email us at support@vocallab.ai.
How does the tool know which character says which line?
An analysis pass reads the manuscript, splits it into chapters, and works out who is speaking for every line before you cast anyone.
Can I reassign a voice after casting?
Yes, change any character's voice and regenerate just the affected chapters instead of rendering the whole book again.
Is there a limit to how many characters I can cast?
No fixed cap — cast as many named characters as the analysis detects across your manuscript.
Can I use a cloned voice for one character and library voices for the rest?
Yes, a cloned voice can sit in the same cast list alongside voices picked straight from the library.
Does casting a full ensemble slow down generation?
No, generation still runs per chapter or across the whole book regardless of how many characters are in the cast.
