Where to sell an AI-narrated audiobook: every store's rule, checked and dated

Store-by-store rules for AI narration, checked 23 September 2026

Each row comes from the store's own help or policy page, read on the date above. Quotes are the store's words. Where a store does not publish a royalty for these titles, the table says so rather than guessing. Rules in this area change often, so the source date is in the last column; check the linked page before you upload.

Libro.fm, an independent bookshop audiobook store, carries AI titles that arrive through distributors but says it "will never knowingly prioritize, publicize, nor market" them (Libro.fm blog, updated 18 Feb 2026). ElevenReader Publishing takes the text, not your audio, and its app narrates it.

Each store in more detail

ACX and Audible: human narration only

ACX is Amazon's audiobook marketplace and the way independent authors get a book onto Audible and Amazon. Its audio submission requirements, updated 15 April 2026, say: "Your submitted audiobook must be narrated by a human unless otherwise authorized: Unauthorized use of text-to-speech, AI, or automated recordings in ACX titles is prohibited." There is no disclosure box that makes an AI title acceptable, and no file format that changes the answer.

If Audible matters to you, the ACX route means a human narrator: yourself, a narrator you pay per finished hour, or a royalty share. Under the royalty model for authors who joined ACX from 26 May 2026, ACX pays a 50% royalty on exclusive titles and 30% on non-exclusive ones. Exclusive means ACX distributes the audiobook and you do not sell it anywhere else; non-exclusive leaves you free to put the same human recording on Google Play, Kobo and your own shop. ACX's Voice Replica, which builds an AI copy of a narrator's voice, is a narrator-side invite beta and not something an author can switch on.

The full ACX rule, what counts as "authorized" and the history of the policy are in our ACX and Audible AI narration policy post.

KDP Virtual Voice: Amazon's AI, with a catch for KDP Select books

Virtual Voice is Amazon narrating your Kindle ebook for you, inside KDP. According to KDP's help pages, it is an invite-only beta on the US marketplace, with 80 voices across US, UK and Australian English, Latin American and Castilian Spanish, French and Italian. The audiobook is clearly labelled as virtual voice, priced between $3.99 and $14.99, pays a 40% royalty, and is sold on Audible, Amazon, Alexa and Amazon Music Unlimited. You cannot upload your own AI files to it: the voices are Amazon's.

The line that matters most is this one: "Audiobooks with virtual voice are exclusive to Audible for the KDP Select enrollment period. This requirement applies to any audio edition of that book." If your ebook is in KDP Select (Kindle Unlimited) and you publish a Virtual Voice edition, you cannot also sell an audio edition of that book on Google Play, Kobo or your own site while it stays enrolled, including audio you made somewhere else. If the ebook is not in KDP Select, that lock does not apply.

So Virtual Voice is a good fit for a US author whose ebook lives in Kindle Unlimited and who wants the audiobook on Audible with no work. It is a poor fit if you want the audio wide, write in a language it does not cover, publish outside the US, or have not been invited. The ebook side of that choice is covered in KDP Select vs wide distribution.

Google Play Books: takes your files, and has its own AI too

Google Play Books is the clearest yes for audio you made yourself. In the Partner Center you upload the audiobook as MP3, WAV, FLAC or a ZIP, and the narrator field offers "Synthesized voice" options, which is how you disclose it. Google then sells it on Google Play.

Google also runs free auto-narration: more than 50 voices, for publishers in 23 countries, paying 52% on those titles. Unusually, the auto-narrated files may be sold elsewhere as long as the book is also on sale on Google Play at no higher price, and Google Play Books is one of the three providers whose packages Voices by INaudio accepts. For a book that is already on Google Play, that is worth comparing with making the files yourself; the trade-off is choice of voice, language coverage and control over pronunciation.

Kobo Writing Life: yes, in any language

Kobo's help centre (updated 23 July 2026) says Kobo will "gladly accept" AI-narrated audiobooks, in any language, with no exclusivity. You set the narrator to Synthesised voice, male, female or unspecified. Kobo pays 45% of the list price on single sales at $2.99 and up, which is $6.75 on a $14.99 audiobook, and 32% on listens through its subscription. The one limit: AI-narrated titles are not sent to library distribution.

For a book in German, Portuguese, Japanese or any other language outside Virtual Voice and Spotify's tool, Kobo and Google Play Books are the two big stores that will take it.

Spotify for Authors: ask first, or use Spotify's own tool

Spotify's digital voice narration help says: "We accept audiobooks with digital voice narration from providers like Google Play Books, ElevenLabs, and more." You tick "This audiobook uses digital voice narration" when you upload, and Spotify does not share those titles with its referral partners. The phrase "and more" is not a list, so if your audio comes from another tool, write to Spotify for Authors support and get a yes before you upload.

Since 9 September 2026 Spotify also has Audiobook Creation Tools: you upload an EPUB and Spotify narrates it, free for up to five audiobooks, for self-published US authors writing in English, with no exclusivity. For an English-language US author that is a route onto Spotify that does not depend on where your files came from.

Voices by INaudio (formerly Findaway Voices): packages only

This is the rule most guides still get wrong. Findaway Voices, now Voices by INaudio, distributes audiobooks to retailers and libraries, and it does accept AI narration, but only as "unmodified LPF packages generated by: Google Play Books, ElevenLabs, Spoken Press". It adds that MP3 files and standard audiobook masters cannot replace the required package. An MP3 from any other tool, however good, does not qualify, and neither does an MP3 exported from one of those three and re-edited.

Apple Books: Apple's own narration only

Apple's digital narration is made by Apple and requested through Draft2Digital, Ingram CoreSource or PublishDrive, in English. The finished title says "Narrated by Apple Books", and under Draft2Digital's terms it is exclusive to Apple at retail. Apple does not describe a route for AI audio made elsewhere, so treat Apple as closed to your own AI files.

Author's Republic: a test programme

Author's Republic, an audiobook distributor, accepts AI-narrated titles as a test, following its naming guidelines (help centre, updated 21 May 2025). It warns that AI narration is "not permitted on all retail and library platforms", so an AI title reaches fewer outlets than a human-narrated one would. Ask which channels your book would reach before you sign.

Direct sales: Gumroad, Payhip or your own site

Selling the files yourself has no AI rule and no exclusivity. You upload the chapter MP3s or a ZIP as a download, set the price and keep what is left after fees. Gumroad takes 10% plus $0.50 per sale plus card processing, so a $14.99 audiobook leaves $12.99 before card fees; Payhip takes 5%, leaving $14.24 before fees. The catch is traffic: these stores send you few browsers of their own, so direct sales work best for authors with a newsletter, a course or a social following. Bundling the audiobook with the ebook, or offering it to people who bought the paperback, are the usual ways in. Our guide to selling your ebook covers the listing side.

The routes by situation

Of the books narrated on Inkfluence AI, counted on 23 September 2026, 90.6% are in English and 9.4% in other languages, mostly German and Spanish. For that 9.4%, the store-made options barely exist and making the files yourself is the practical route. The AI audiobook trends page covers what authors narrate by genre.

What an Inkfluence AI audiobook is, and where it can go

Inkfluence AI narrates a book you wrote or imported, chapter by chapter, in any of 49 narrators across 14 languages. You pick the narrator, fix any word it says wrong once for the whole book, and record all chapters or just the ones you changed. When it is done you have three downloads:

• An MP3 per chapter, as recorded, to listen to or share.
• One MP3 of the whole book, for a single download on your own site.
• A chapter ZIP: one MP3 per chapter, numbered in reading order, at 44.1 kHz, 192 kbps constant bitrate, mono, loudness-normalised to ACX's technical window, with room tone at the head and tail, plus separate opening and closing credits files.

Those files are made for the routes that take your own AI audio: Google Play Books, Kobo, Author's Republic's test programme and direct sales. They meet ACX's technical audio spec, but that does not make them eligible for ACX, which requires a human narrator. They are not an LPF package, so they cannot go to Voices by INaudio. We do not publish audio to any store for you: you upload the files yourself, which keeps you in charge of the listing and the disclosure.

How many chapters you can record depends on the plan. Creator includes 15 audiobook chapters a month in Standard quality; Premium includes 30 a month and adds the HD narrators. The free plan includes none, but purchased credits work on any plan in Standard quality. A median narrated book on the platform is eight chapters, so one book usually fits in a Creator month; the audiobook length calculator estimates yours from its word count. The help article on ACX shows how to prepare the chapter ZIP.

Before you upload: a short checklist

1. Decide on Virtual Voice first. If your ebook is in KDP Select and you might accept an invitation, remember it makes every audio edition Audible-only while enrolled. Choose before you upload anywhere else.
2. Use each store's disclosure field. "Synthesized voice" on Google Play Books, "Synthesised voice" on Kobo, the digital voice box on Spotify. On your own shop, say it in the description.
3. Listen to every chapter. Names, invented words and numbers are where AI narration slips. Fix a word once and re-record only the chapters that use it.
4. Upload the chapter files, in order. Stores that take audiobooks generally want one file per chapter; the merged MP3 is better suited to a single download.
5. Check you hold the audio rights. If a publisher has your book, the audio rights may sit with them. If you wrote it, they are yours.
6. Re-read the store's page on the day. Every rule on this page is dated because these rules move. The linked sources are the ones to trust over any guide, including this one.
