Novel to Audiobook Converter: AI, Full Cast
Turn a novel into an audiobook with AI: one narrator, 50,000 characters a job, or a full cast that keeps its voices across the book. What a whole book costs.
Last updated: 2026-10-08
There are two ways to turn a novel into an audiobook on VoiceSmiths: one narrator for the whole book, or a full cast with a voice for the narrator and every character. Both have the same standard rate per character. Try the full cast below: paste a passage and see who the AI finds in it, free.

One narrator lives in long-form audiobooks; the full cast in the audio drama studio. Not sure? Render one chapter both ways and play them to a few readers.

Doing the whole book
- Split by chapter. Full-cast chapters stay under 8,000 characters, so split long ones; long-form jobs take up to 50,000, so several short chapters can go together.
- Start a series. Get chapter one's cast right, then add it to a new series. Every later chapter gives returning characters the same voice.
- Render chapter by chapter. Each gives you an MP3 and SRT; failed renders are refunded. Everything lands in My works in order.
- Spot-check. Listen for names, invented words and acronyms. Respell anything misread in the text (phonetically if needed) and render that chapter again; shorter chapters make fixes cheaper.

Before you publish
- Rights. Audio rights to a published novel usually sit with the publisher or author; without them you can't sell the audiobook. Your own books and public-domain classics (like those in the theater) are fine.
- AI disclosure. Every file carries an AI-generated label in its metadata. Stores have their own rules for AI narration; check them before you upload.
- Sample first. Share a chapter or two and ask readers whether the voices fit the characters before rendering the rest.

FAQ
One narrator or a full cast? Literary fiction, non-fiction and anything carried by narration suits one narrator: the long-form mode takes up to 50,000 characters at a time with one voice and one subtitle track. Dialogue-heavy genre fiction suits a full cast: the audio drama studio takes up to 8,000 characters per chapter and gives the narrator and every character a voice. Both have the same standard rate, 70 credits per 1,000 characters; a single narrator on the Flash model is 40.
What does a whole novel cost? A 90,000-word novel is about 500,000 characters: 35,000 credits, about 9.7 hours of audio, roughly $280–410 at monthly-plan rates. Both modes are 70 credits per 1,000 characters; a single narrator on the Flash model is 40, about 20,000 credits for the book.
How do characters keep the same voice in every chapter? With a full cast, add the first chapter to a series. Each chapter you render teaches the series its cast, and the next chapter gives every returning character the same voice; newcomers get their own.
Can I publish the audiobook? Yes, if you hold the audio rights: your own book, a licensed one, or a public-domain classic. Every file carries an AI-generated label in its metadata; follow your store's rules for disclosing AI narration.
What do I download? An MP3 and a line-timed SRT per chapter; a full-cast chapter also exports its script and a vertical video. Everything is kept in My works.
