Accepts a synthetic narration if you label it
Kobo Writing Life
Rakuten Kobo’s own help centre says it accepts AI-narrated audiobooks. Credit the narrator as a synthesised voice, not as a person.

Who will sell a Listening Room audiobook
The studio makes a synthetic narration: a named voice, disclosed as synthetic, in MP3 at 44.1 kHz and 192 kbps. Some shops will list that. Some will not take the file at all. This page is the split, checked in October 2026. Policies move. Read the shop’s own page again on the day you upload.
Published by Stewart Ferris. The recording itself is made in the studio.
Shops that may take the file
Each of these has a longer page: market, contact, file rules, and how the money works.
Accepts an uploaded AI audiobook if you mark it synthesised
Google Play Books
In the Partner Center, an uploaded audiobook asks you to choose Human narrator or Synthesized voice. Google’s own help says: if you upload an AI-generated audiobook, select Synthesized voice.
What an author needs to knowAccepts digital narration, but names some providers and not others
Spotify for Authors
Spotify’s help page says it accepts digital voice narration “from providers like Google Play Books, ElevenLabs, and more.” The Listening Room uses xAI voices, which are not on that named list. Ask Spotify before you count on a yes.
What an author needs to knowA test, and not every shop on their list will take it
Author’s Republic
Author’s Republic says it is testing distribution of AI-voice audiobooks that were already produced on another platform. It also says those books are not permitted on all retail and library platforms.
What an author needs to knowYou are the shop. There is no audiobook gatekeeper.
Gumroad
Gumroad sells the file you upload. It does not review narration the way Audible does. The buyer is someone you send, or someone who finds the product on Gumroad.
What an author needs to knowA direct download shop, with no synthetic-voice ban
Payhip
Payhip sells digital files from a page you control. Nothing in its shop rules turns a synthetic audiobook away. You have to bring the reader.
What an author needs to knowIf you can take a payment, you can sell the file
Your own website
A page on your own site, with Stripe, PayPal, or a delivery service such as BookFunnel, is a shop you control. No audiobook retailer sits in the middle to reject the voice.

Shops that will not sell this recording
These are closed to a file made here. A different programme on the same company — Amazon generating its own Virtual Voice, or Apple narrating an ebook itself — is not the same thing as selling your Listening Room master.
Audible, through ACX
ACX requires a human narrator unless Audible has authorised something else, and it prohibits unauthorised text-to-speech. A Listening Room recording is that unauthorised kind of file. Do not submit it. Amazon’s Virtual Voice is a separate beta: Amazon generates the audio from a Kindle book, labels it, and you do not upload this studio’s MP3s.
Their pageApple Books, for this file
Apple’s digital narration is made by Apple and credited “Narrated by Apple Books”. You nominate an English ebook that is already on Apple Books, through Draft2Digital, Ingram CoreSource, or PublishDrive. Apple’s own guide does not describe uploading a finished synthetic master from somewhere else. Their programme will not sell the Listening Room recording.
Their pageVoices by INaudio (formerly Findaway Voices)
Spotify says audiobooks that use digital voice narration are not shared with its referral partner. INaudio’s wider retail and library network is that partner. Do not plan on a Listening Room file travelling to Apple, Audible, or libraries through that door.
Their pageOverDrive, Libby, and Hoopla
Libraries do not take a file straight from an author. Copies arrive through a distributor. Kobo does not promise library distribution for a synthesised voice, Author’s Republic says AI narration is not allowed on every library platform, and the INaudio referral path excludes digital-voice uploads. Assume a library app is closed until a distributor says otherwise in writing.
Barnes & Noble, Libro.fm, Chirp, Everand, Audiobooks.com, and Storytel
None of these offers a direct upload we can point an indie author to for a synthetic master. They are supplied by publishers, by Audible, or by distributors such as INaudio. Until one of them publishes a door for an outside synthetic file, treat them as closed to a Listening Room recording.
Before you upload anywhere
- Credit a synthetic voice. Never put a person’s name in the narrator field.
- The Audio Publishers Association’s naming guidance is the industry label: a synthesised voice, or “AI Voice”, not a human reader. Read their guidelines.
- Listening Room files match the common retail shape: one MP3 per section, opening and closing credits, 44.1 kHz, 192 kbps. They are not a booth recording. Shops that measure room tone and a −60 dB noise floor may still reject them.
- Keep the rights. You are selling a recording of a manuscript you have the right to record.
