How to Turn a NovelAI Story Into an Audiobook

You can turn a NovelAI story into an audiobook in three moves: export the story as plain text, cast a voice for each character, and render it to a downloadable MP3. NovelAI helps you write the prose; AudioProducer.ai takes that finished text and turns it into multi-voice audio. The one shortcut most co-writers miss is that your Lorebook is already a cast list, so let us start there and work through the whole path.

Get your NovelAI story out as plain text

The first step is the same one every AI-assisted writer hits: get the words out of the editor and into a plain file you control. Copy your story out of NovelAI and paste it into a plain text document, or save it as a .txt file. You do not need anything fancier than that. AudioProducer reads pasted text or an EPUB, so a clean text export is all you have to hand it.

If your story lives across several sessions or documents, stitch them into one continuous file in reading order before you go any further. A single ordered text file is far easier to cast and narrate than a pile of fragments, and it saves you re-checking scene order later.

Clean the co-writing tells before you narrate

Co-written prose carries small tells that your eye skips but your ear will not. Watch for a stray author's note left inline, a scene that restarts because you regenerated it, duplicated sentences where two passes overlapped, and bracketed prompt fragments that were never meant to be read aloud. Delete them now, in the text file, before any voice touches them.

Also decide what actually gets spoken. Narration and dialogue both read fine as audio, but stage directions you wrote only to steer the model ("continue in a tense tone") are not part of the story and should come out. Watch too for the model's habit of restating what just happened at the top of a new passage; on the page a little repetition passes, but read aloud it lands as the narrator saying the same thing twice. The goal is a file that reads start to finish as the story a listener should hear. If you drafted with another tool as well, the cleanup notes in turning a ChatGPT story into an audiobook and turning a Claude story into an audiobook apply the same way, and a Sudowrite draft cleans up along the same lines in converting a Sudowrite draft to an audiobook.

Turn your Lorebook into a cast list

This is the part that is specific to NovelAI. If you kept a Lorebook while you wrote, you already did the hardest part of casting an audiobook: you named your characters and wrote down who they are. Those entries are a cast list waiting to be used.

Before you import, skim your Lorebook and jot down each speaking character and a one-line sense of their voice: age, register, whether they are warm or clipped, fast or slow. You are not configuring anything yet, just deciding intent. A protagonist who reads as a dry, tired narrator and a younger sibling who talks fast and bright will each want a distinct voice, and your own notes already tell you which is which. Characters who never speak, or who appear once in a background line, do not need their own voice; fold them into the narrator.

Watch for one thing that trips up co-written stories in particular: a character who was renamed partway through, or who shows up under a nickname in dialogue and a full name in narration. Note both spellings against the same voice so the cast stays consistent. Doing this pass from your Lorebook first means that when you cast in AudioProducer, you are matching voices to characters you have already defined, instead of meeting your own cast for the first time.

Import and let AudioProducer auto-assign the voices

Paste your cleaned text into AudioProducer, or upload it as an EPUB. AudioProducer separates narration from dialogue and can Auto-Assign a distinct voice to each character it finds, so the fast, bright sibling and the dry narrator you flagged from your Lorebook end up sounding like two different people rather than one reader doing all the parts.

Use your Lorebook notes to sanity-check the assignment. If a voice does not fit a character you know well, swap it for one that does before you render. This is where a few minutes of your own judgment pays off: the tool casts quickly, and you are the one who knows the character.

Add sound effects, pace the scenes, and export the MP3

With voices set, you can add sound effects where a scene calls for one and let the pacing breathe at scene breaks so a listener can feel the shift. Keep effects sparse; in audio, one well-placed sound does more than a dozen, and a beat of silence at a chapter turn often reads better than any effect at all. Preview a scene before you commit to the whole file, because a voice that looked right in a list can sound wrong once it is speaking your character's lines. When it sounds like the story you wrote, render and download your audiobook as an MP3. The file is yours to keep.

If your co-written story runs long, split it into chapters before you export rather than shipping one enormous track. The chapter-break guidance in how to split your manuscript into audiobook chapters covers where to place breaks and how long each one should run for comfortable listening, so this post does not re-walk that ground.

What the free tier covers, and who owns the result

The free tier gives you 1,200 words a month, which is enough to run one scene end to end and hear how your cast sounds before you commit to a full book. Quota is measured in words per month, so a short chapter is a cheap way to test.

Two things worth being clear about. AudioProducer makes the audio; it does not write your fiction for you, so the story is entirely yours, NovelAI-assisted or not. And it does not publish, upload, or distribute anything on your behalf. You download the MP3 and decide where it goes, whether that is a podcast feed, a personal archive, or nowhere at all. Rights and disclosure for AI-assisted work are yours to handle. For the full family of related walkthroughs, see the full article index.
