AI Audiobook Studio
Turn a finished book into a multi-voice audiobook: a distinct AI voice for every character, emotion-aware delivery, a studio where you can retouch any single paragraph, and a mastered export ready for retail.
Give every character their own voice
Pick a book, choose a narrator, and the studio casts your characters automatically, renders the audiobook chapter by chapter, and masters it into files you can actually publish.
How it works
Pick your book
Choose any finished book in your library — fiction, non-fiction, or a visual book. The chapter text already in your editor is the script, so nothing gets pasted or re-uploaded.
Pick your narrator
Every audiobook is narrated with ElevenLabs v3, our highest quality model, the one that understands emotion tags. Pick your narrator from 25 professional voices, each with a preview you can play before you spend a credit.
Review the casting
The studio reads the book, finds who speaks each line, and proposes a voice for every character. You review the cast list and swap any voice before a second of audio is rendered.
Render chapter by chapter
Chapters render one at a time so you can listen as you go, stop, adjust, and continue. Nothing forces you to commit the whole book in one shot.
Fine-tune any paragraph
Hear a line you don't like? Regenerate it on its own for a few credits, or re-record it together with its neighbouring lines so the delivery still matches. Either way the rest of the chapter stays exactly as it was.
Export mastered files
Every chapter is loudness-mastered in your browser to the preset you pick — retail audiobook (-19 LUFS) or streaming (-14 LUFS) — and encoded at 128, 192 or 256 kbps. Export it as one merged MP3 with a chapter-markers file, a ZIP of numbered per-chapter MP3s, or an M4B with chapter markers built in, each carrying your title, author and cover art.
What the studio does
Everything below happens inside AIWriteBook — no separate DAW, no voice actor, no recording session.
A voice per character
Dialogue is annotated automatically by speaker, then cast to distinct voices. You stay in control: the cast list is yours to review and change before rendering.
25 professional voices, all multilingual
Eleven female, thirteen male and one neutral narrator voice. The accent labels — American, British, Australian, Swedish — describe how a voice sounds, not what it can read: every voice narrates in the language your book is written in. Preview any of them, in English or in French, Spanish, German, Italian, Portuguese, Japanese or Norwegian, before you commit.
Emotion-aware delivery
The studio adds emotion tags to the script where the scene calls for them, so a whispered line lands as a whisper and a shouted one as a shout.
Whole scenes recorded in one take
Neighbouring paragraphs are narrated together in a single request, so the voices react to each other and the pacing carries across a scene instead of resetting every paragraph.
Surgical paragraph regeneration
Re-render a single paragraph rather than the whole chapter. Fixing one bad line costs you one line, not an hour.
Retail-grade mastered export
Loudness normalisation to a retail (-19 LUFS) or streaming (-14 LUFS) target and MP3 or M4B encoding at 128, 192 or 256 kbps are applied to every chapter, which is the shape distributors expect from a finished audiobook.
Chapter files, merged file, and markers
Download a ZIP of numbered chapter files, the whole audiobook as one merged MP3 with a chapter-markers text file, or an M4B with chapters built in — whichever your distribution route asks for.
Fiction, non-fiction, and visual books
Multi-voice casting shines in dialogue-heavy fiction, and a single steady narrator handles non-fiction and visual books just as well.
Where you can publish it
You export standard MP3, ZIP and M4B files, so they work anywhere audiobooks are sold. Here are the routes authors use most.
Where AI narration is accepted
- Spotify, through Findaway Voices — AI narration is allowed as long as you disclose that the audiobook is AI-narrated.
- Google Play Books, which accepts self-published audio and has its own AI narration programme.
- Your own author page on AIWriteBook, your website, your newsletter, or a podcast feed — direct sales keep the whole margin and have no exclusivity strings.
Before you upload
- Store policies on AI narration differ and keep changing, and most simply ask you to declare it. Check the policy wherever you plan to publish before you upload.
- Amazon also runs KDP Virtual Voice, which narrates your ebook with Amazon's own voices inside KDP — a separate route you can use alongside the files you export here.
What it costs
The Audiobook Studio is a paid feature and it bills in credits by the character, so a short book costs less than a long one.
Narration is 1 credit per 12.5 characters. Multi-voice casting adds 20% on top, and while the studio is in beta every render is then discounted by 75% — a temporary launch discount that will end, after which the full rate applies. The exact cost is shown before you render, and you can see the wider credit pricing for everything else.
Frequently asked questions
You get standard MP3, ZIP and M4B files, so they go anywhere audiobooks are sold. Store policies on AI narration differ and keep changing, and most simply ask you to declare that the narration is AI, so check the policy wherever you plan to publish. Spotify via Findaway Voices and Google Play Books accept AI narration when you disclose it, Amazon also offers KDP Virtual Voice on your ebook, and you can always sell the files yourself.
The studio reads your book, works out which character speaks each line of dialogue, and proposes a voice for each of them plus the narrator. You get a cast list to review and can swap any voice before rendering. If you would rather have one steady narrator for the whole book, turn multi-voice off and keep the single narrator.
Yes. The studio narrates books in all 31 languages AIWriteBook writes in — across 38 regional variants — including French, Spanish, German, Italian, Portuguese, Japanese, Norwegian, Dutch, Polish, Korean, Chinese, Hindi, Arabic, Swedish, Ukrainian, Danish, Finnish, Czech, Greek, Hebrew, Romanian, Hungarian, Turkish, Vietnamese, Thai, Indonesian, Malay, Tagalog, Bengali and Catalan. You do not pick a language anywhere: the model reads the language your book is written in, and all 25 voices are multilingual. In the voice picker you can hear each voice speak French, Spanish, German, Italian, Portuguese, Japanese or Norwegian before choosing.
Not today. The studio narrates with our library of 25 professional voices only — there is no voice cloning and no way to upload a voice sample of your own or of a narrator you have hired. It is one of the most requested things on our public roadmap and you can vote for it there, but nothing about it has shipped yet, so please do not plan a launch around it.
It is priced per character: 1 credit per 12.5 characters. Multi-voice casting adds 20%, and the temporary beta discount then takes 75% off. With the discount a 50,000-character book is about 1,200 credits single-voice, or about 1,440 credits with multi-voice casting; without it those figures are 4,000 and 4,800. The studio shows you the exact figure for the chapter and the whole book before you render anything.
Regenerate that paragraph. You can change the voice, adjust the emotion tag, or reword the line, then either re-record just that line or re-record it together with the lines it was narrated with so the delivery still matches. The rest of the chapter is untouched, so you never re-pay for audio that was already fine.
By respelling it. There is no pronunciation or stress dictionary — the v3 engine does not support phoneme dictionaries — so the fix is to open the line in the studio, spell the awkward name the way it should sound, add a delivery note if the emphasis is off, and re-record just that line. The respelling only lives in the audio script; your book text is untouched.
Loudness-mastered MP3 at 44.1 kHz and 192 kbps: one file per chapter, one merged file for the whole audiobook, and chapter markers. That covers what distributors, podcast feeds, and direct downloads ask for.
Yes. Multi-voice casting is built for dialogue, so it is most dramatic in fiction, but non-fiction and visual books narrate cleanly with a single voice and get the same emotion tags, paragraph-level editing, and mastered export.
Writing and planning your book is free to start. Audiobook production is available on the Pro and Ultra plans, and on AppSumo Tier 2 and above. It runs on credits, billed per character with the 75% beta discount applied, so you will need a plan with credits to render. You can read more about narration on the audiobook generator feature page.
