Audiobook Distributors Compared: Which Route Fits Your Book

If you want Audible with a human narrator, ACX is the route this page documents, and it asks you to choose between exclusive and non-exclusive distribution. If your narration is AI, ACX's rule currently points elsewhere: Spotify for Authors, Voices by INaudio, Author's Republic and Kobo each document some form of digital narration; ElevenReader Publishing's terms are silent on how audio is produced. This page compares nine routes on what their own pages say, and it flags what stayed unread or unpublished. Use it after you have read the full route from manuscript to listing.

Routes, exclusivity and AI at a glance

Each row reflects what the linked official pages said on November 8, 2026. "Not published on the pages read" means the page was read and stated no rate, not that none exists.

Royalties as documented

Royalty rates are not on a common base, so a row-to-row percentage comparison misleads. Run your own numbers in the royalty calculator.

The same sale at a $15 list price, as an estimate

Stated rates can be set side by side only where the base is stated. These are estimates from the percentages above, and a price you set is not always the price a retailer charges.

None of the three calculated figures is confirmed for AI-narrated titles. Spotify's Opt-In terms and INaudio's royalty article do not mention digital voice, and Kobo's FAQ line does not separate AI narration. The Spotify line applies only to opted-in content, and those terms do not say whether a title uploaded through Spotify for Authors is covered, so do not use $7.50 for an ordinary upload without confirming it.

Draft2Digital's two commission descriptions show why the base matters. If a channel paid $6.00 on a $15.00 sale, a 15% deduction from payments received would be $0.90, and about 10% of retail price would be $1.50. That example is invented to show the difference. Treat the Terms as the operative wording and ask Draft2Digital which applies to your books.

ACX, Voices by INaudio and Author's Republic head to head

These three are the usual choice for an author going beyond one store, and they differ most on AI narration and on Audible.

Treat Author's Republic's retailer list as its own statement, not as those retailers' rules. The list names Amazon/Audible, while ACX's own page requires human narration on ACX submissions unless otherwise authorized and does not say what applies to titles delivered by a distributor. Ask Author's Republic in writing before you count on any store on that list. Its FAQ also says partners reserve the right to decide which titles they carry.

Exclusivity: what each commitment ties up

Exclusivity differs by what it covers, so one word can mean a whole book or a single file. As read on 2026-11-08:

• ACX exclusive ties up that audiobook's distribution for the seven-year term described below.
• Draft2Digital's Apple digital narration ties up only the Apple-made file. You may still make or commission other recordings of the same work.
• Google's auto-narration is not exclusive, but you must also sell on Google Play in every country where you sell elsewhere, and Google's list price cannot exceed other retailers' prices.
• Voices by INaudio states no exclusivity agreement, and Spotify's upload article calls its distribution non-exclusive. ElevenReader's Payment Terms contain no exclusivity clause.
• Royalty Share at ACX requires exclusive distribution, so it rules out a wide release for that recording. Author's Republic's FAQ warns that a royalty-share title may not be able to change its agreement.

Using several non-exclusive routes creates its own rule: send each retailer one copy. Author's Republic's FAQ says delivering the same audiobook to a retailer through several distributors violates its terms and can bring complaints or takedowns. Deselect any store you already serve directly.

Where Apple Books fits

Apple Books has no row above because this page compares distributors, but two of those routes reach it. ACX's exclusive option includes Apple Books, and Draft2Digital is a named partner for Apple's own digital narration.

Apple's Audiobooks Formatting Guidelines 1.3.2, sections 1.15, 3.9 and 5.14, require audiobooks narrated by AI to state this in the title or narrator field and reference it in the description. That is a label rule. No Apple page read says whether third-party AI audio is accepted, so do not read the guideline as permission. See Apple Books.

ACX in detail: terms that decide the choice

ACX gives Audible a seven-year distribution term under either option, per its distribution page (Oct 21, 2026). Exclusive means Audible, Amazon and Apple Books only, and you are "not permitted to distribute or sell your audiobook on any site or store outside of Audible". Non-exclusive lets you sell elsewhere in any format, arranged independently of ACX. ACX does not distribute to libraries, so library reach needs non-exclusive plus another route. See the ACX page.

Findaway Voices and Voices by INaudio

Findaway Voices appears to have become Voices by INaudio, and the evidence is Spotify's and INaudio's own pages. Spotify's support article describes INaudio as formerly Findaway Voices by Spotify, and INaudio's site uses the Voices by INaudio name (the page we read does not itself announce a rename) and offers non-exclusive distribution to retail, library and educational channels. Spotify's August 2025 post says it is partnering with INaudio for wider distribution. Stated rates are in the royalty table above, and INaudio says the full partner rate list is inside your account. Details: Voices by INaudio and Spotify for Authors.

How to choose

• Human narrator, Audible matters most: ACX. Compare exclusive and non-exclusive on your own numbers.
• Human narrator, many stores: non-exclusive ACX alongside a wide route, or a wide distributor alone. Libraries need a route that serves them; see libraries.
• AI narration: Spotify, INaudio (unmodified LPF only), Author's Republic, Kobo with the label, Google's auto-narration Beta, or ElevenReader Publishing (its Payment Terms do not say whether AI-produced audio qualifies, so confirm with ElevenLabs). ACX: no route is documented for third-party AI audio, and it is prohibited unless authorized.
• AI audio from a tool INaudio does not name: INaudio's rule excludes it. Author's Republic's FAQ says any AI engine, and Spotify and Kobo do not limit themselves to a closed list. Check the file requirements first.
• An ebook but no audio, and you want Apple Books: Apple's digital narration through Draft2Digital. Remember the Apple-made file cannot go to other stores apart from library channels.
• Who should not choose which: if you plan to edit AI audio outside its generator, INaudio's rule excludes you. See Google Play, Kobo and Draft2Digital for each store.

What stayed unpublished or unread

Several facts a distributor comparison normally rests on are not available from the pages read on 2026-11-08, and silence is not a yes or a no.

• Royalty rates for AI-narrated titles at Spotify and INaudio.
• Whether a title uploaded through Spotify for Authors falls under the Opt-In terms.
• Which partners accept digitally narrated titles at INaudio, beyond its own account screens.
• Author's Republic's technical requirements and what partners pay it. Its AI help article returned HTTP 403, so this page relies on the FAQ, whose retailer list is dated October 2026.
• Google's and PublishDrive's royalty rates, and Draft2Digital's commission on INaudio sales.
• Any Kobo exclusivity or library term, because its pages were blocked.
