ACX Audiobook Guide for Self-Published Authors
ACX (Audiobook Creation Exchange) is Amazon's platform for producing and distributing audiobooks to Audible, Amazon, and iTunes. For self-published authors, it's the primary path to the $1.5 billion+ audiobook market without a traditional publishing deal — but the narrator hiring process, royalty structure, and exclusivity decisions require careful navigation.

How do I find and audition narrators on ACX?+
On ACX, you create a title page for your book with sample text (a page or two from your manuscript). Narrators on ACX browse open titles and submit auditions — recordings of your sample text in their voice. You can also browse narrator profiles and invite specific narrators to audition. Evaluate auditions for: vocal quality appropriate to your genre, character voice differentiation, pacing, and emotional range. Request auditions from multiple narrators before deciding. For romance, narrator gender compatibility with your POV character matters significantly to reader expectations.
What is the difference between royalty share and per-finished-hour on ACX?+
Per-finished-hour (PFH): you pay the narrator a flat rate per hour of finished audio. A 90,000-word novel produces roughly 10 hours of audio. At $200 PFH, that's $2,000 upfront. You keep 100% of royalties (minus ACX's percentage). Royalty share: no upfront cost — you and the narrator each receive 20% royalty (ACX takes the remaining 60%). Royalty share requires 7-year ACX exclusivity. PFH gives you the option of non-exclusive distribution. Authors with established sales records and production budgets favor PFH; debut authors often start with royalty share.
What does ACX exclusivity mean in practice?+
ACX exclusivity means your audiobook can only be sold through Audible, Amazon, and iTunes — you cannot distribute through Findaway Voices, Libro.fm, or library platforms like hoopla or OverDrive during the exclusivity period. Exclusive distribution earns 40% royalty on Audible sales. Non-exclusive distribution earns 25% royalty and allows wide distribution. The royalty share option automatically requires exclusivity. Authors evaluate exclusivity based on where their readers buy audiobooks — if your audience is primarily Audible, the higher royalty may justify the exclusivity trade-off.
How do I market my ACX audiobook after publication?+
Audiobook marketing follows similar patterns to ebook marketing with some platform-specific tactics: Audible daily deals (comparable to Kindle countdown deals) when available; Whispersync coordination (price your ebook low on Amazon so readers can add the audiobook at Whispersync price); reviewer outreach to audiobook-specific reviewers and BookTok/Bookstagram accounts that cover audio; and listing your audiobook in your author newsletter with direct Audible links. Review momentum for audiobooks works the same way as ebooks — more early reviews drive visibility in Audible's algorithm.
Can I use AI narration for ACX audiobooks?+
As of 2024–2025, ACX has specific policies around AI-generated narration that are evolving. Authors should review ACX's current terms before pursuing AI narration — the platform requires disclosure and may have restrictions on distribution of AI-narrated titles. The audiobook industry and narrator community are actively engaged with this issue. Some distribution platforms outside ACX have clearer policies. Always check current ACX terms of service, as policies in this area are changing rapidly.
How long is the ACX narrator contract and can I change narrators mid-series?+
ACX agreements are typically per-book, not per-series — you are not locked into a narrator for your entire series by the contract itself. However, series continuity is a significant reader consideration: changing narrators mid-series produces reader complaints and can affect series sales. Readers form strong attachments to audiobook narrators and often won't follow a series if the narrator changes. Carefully evaluate a narrator before committing a long series — audition them with your most challenging characters and ask about their availability for multiple books before signing.
