BookZeta can narrate your book with AI voices and export it as a finished audiobook file — complete with chapter markers so listeners can jump between chapters. It's a way to turn a manuscript you've already written into audio without booking a studio or hiring a narrator.
How to generate an audiobook
- Open your project and choose Generate audiobook.
- Select a voice and confirm.
- Generation runs in the background — you can keep working and check the status as it goes.
- Download the finished file when it's ready.
Because narration is processed chapter by chapter, longer books take longer to finish. There's no need to wait on the page while it runs.
File formats: M4B vs MP3
You can export in two formats:
- M4B — the standard audiobook format. It bundles the whole book into one file and carries chapter markers, so apps show your chapters and let listeners skip between them. This is the better choice for a proper audiobook experience.
- MP3 — a widely-compatible audio format that plays almost anywhere, useful when a destination specifically asks for MP3.
What it costs
Audio generation spends Creation Points per chapter, so the total depends on how many chapters your book has. As with every AI action in BookZeta, you'll see the cost before you confirm.
Tips for a good result
- Tidy your text first. The narration follows your manuscript, so fix typos and awkward phrasing before you generate — they'll be read aloud as written.
- Listen to a sample voice before committing to the full book.
- Use clear chapter breaks so the chapter markers land where you expect.
Before you sell on Audible
If you plan to distribute through Audible, read the ACX / Audible rules first. They have specific audio requirements, and it's far easier to meet them up front than to rework a finished file. BookZeta gives you the audio file; meeting each platform's current spec is up to you.
