How to choose an audiobook service
A human narrator or an AI voice?
ACX and Author’s Republic connect you with human narrators. ElevenLabs, Kindle Virtual Voice and Google Play’s auto-narration use computer voices: much cheaper and faster, and in Amazon’s and Google’s case free, but listeners and some stores treat them differently. Kindle Virtual Voice is still an invite-only beta for US KDP authors.
How do you pay the narrator?
On ACX you can pay a narrator per finished hour, or split royalties with them instead of paying up front. A royalty share costs nothing at the start, but you give up half of what the audiobook earns.
Exclusive to Audible, or wide?
ACX pays more if the audiobook is exclusive to Audible, Amazon and Apple: under the model it introduced on May 26, 2026, 50% exclusive against 30% non-exclusive (the old 40% and 25% end at the end of the year). Voices by INaudio, the service that used to be Findaway Voices, and Author’s Republic distribute to many more stores and libraries, and both say the author keeps 80% of the royalties they receive.
In audiobook production, a product earns up to 50 points for the author jobs its vendor’s pages confirm (human narrators, AI narration, distribution to stores, royalty share or pay up front, non-exclusive option and royalty rate stated), 25 for what a year costs and 25 for how many people in the US search for it by name. The formula, and what it leaves out, is on how we score software.
What is the best way to make an audiobook as a self-published author?
For Audible with a human narrator, ACX is Amazon’s own route. For an AI voice at no cost, Kindle Virtual Voice (by invitation) and Google Play auto-narration. For wide distribution of a finished audiobook, Voices by INaudio or Author’s Republic.
What happened to Findaway Voices?
Findaway Voices was bought by INaudio in 2025 and now runs as Voices by INaudio; findawayvoices.com redirects there.
Can I sell an AI-narrated audiobook on Audible?
Through Kindle Virtual Voice, yes: it publishes computer-narrated audiobooks of eligible Kindle ebooks to Audible, for US authors invited to the beta.
