ST Mastering · Audiobook Production

AI-narrated
audiobooks.

Your manuscript, produced as an audiobook with a synthetic voice — generated, edited, proofed against your text and mastered to retail specification by the studio.

A different product to human narration, with a different price and one catch you need to know before you order: Audible and ACX do not accept AI-narrated audiobooks. Where it can and cannot go is set out below, before you pay.

Read this before you order

Most retail platforms do not accept AI-generated narration, and that includes the biggest one. ACX — the route on to Audible and Amazon — prohibits it outright. If Audible is where you need your audiobook to be, this product is not for you, and our human narration service is.

“Unauthorized use of text-to-speech, AI, or automated recordings in ACX titles is prohibited.”ACX audio submission requirements, quoted from their own rules

The same applies to a clone of your own voice. A voice being yours does not make the recording human-narrated in a platform’s eyes — it is still synthetic speech, and it is still refused.

We cannot appeal this, influence it, or work around it, and we will not try. Concealing AI origin from a platform is the fastest route to a terminated publishing account. Every order for this service asks you to confirm you understand all of the above.

Where it can be sold

The platform picture

This is the state of play as we understand it today. Platform policy on AI narration is changing quickly — in both directions — so we check it at the time you order rather than asking you to trust a table on a web page.

PlatformAI narrationWhat that means
ACX / AudibleNot acceptedProhibited in their submission rules. Audible has said it is working towards accepting third-party synthetic speech, with no date given.
SpotifyAcceptedAccepted with disclosure. You tick a “digital voice narration” box and Spotify adds a line to your description telling listeners. Spotify does not pass these titles to its referral partners.
Apple BooksTheir own systemApple accept synthetic narration produced through their own system, using their voices. Whether they will take an AI file made elsewhere is a separate question — we check it before you order.
Google Play BooksTheir own systemAs Apple: Google’s auto-narration uses Google’s voices. We confirm the position for uploaded AI audio at the time you order.
Amazon KDP Virtual VoiceTheir own systemAmazon’s own voices only, clearly labelled on the listing. It does not accept an AI file produced elsewhere.
Everywhere elseVariesAggregators and library services each set their own rule and several are mid-change. Tell us your target and we will tell you what we know.
What you get

Generated, then actually produced

A synthetic voice on its own is a rough draft. The work is what happens afterwards — and that is the part we do.

  • A voice matched to your book — chosen from current synthetic voices, or cloned from a sample you supply and are entitled to use
  • Full-length generation — chapter by chapter, joined and paced properly, not a raw dump from a text box
  • Pronunciation work — names, places, invented words and homographs corrected and regenerated until they are right
  • Proof checking included — every chapter checked against your manuscript, word for word. Synthetic voices drift, skip and occasionally produce nonsense; catching that is the job, and it is in the price
  • Mastering to retail specification — −23 to −18 dB RMS, −3 dB peak ceiling, noise floor under −60 dB
  • Your own dashboard — progress, files and approvals in one place
  • Where it can be sold — checked against your platforms before you pay, not after

Voice cloning

Bring your own voice

We can clone a voice from a sample you supply and narrate your book in it — your own voice, or one you have permission to use. It is the closest this product gets to a human read, and authors like hearing their own book in their own voice.

  • You supply the sample — a clean spoken recording, the longer and drier the better
  • You confirm you are entitled to use it — your own voice, or written permission from whoever owns it
  • You indemnify us for what you supply — we produce what you ask for in good faith; the right to use the voice is yours to hold, and your confirmation is recorded against your order
  • A clone is still AI to a platform — cloning your own voice does not make the audiobook eligible on Audible or ACX
From our own testing: cloned voices are not perfectly consistent over a full book. They wander, occasionally produce nonsense, and have to be generated in lengths and joined. That is precisely why this service includes a full proof-check and pronunciation pass — and why an AI audiobook is not simply a cheaper human one. If you want a performance, buy a narrator.
How it works

Five steps, no surprises

Price it and book your start date

The calculator above is the quote. Book the slot that suits you.

Send your manuscript

Attach it to your order — Word, PDF, RTF or plain text — along with a voice sample if you want your own voice cloned. Files upload once payment clears.

We build the voice

Your book is matched to a current synthetic voice, or the sample you supplied is cloned.

Generate, fix, proof, master

The book is generated chapter by chapter. Pronunciation is corrected and regenerated, mistakes and drift are cut, every chapter is checked against your manuscript, and the set is mastered to retail specification.

Delivery

Publish-ready files arrive in your dashboard on the date the calculator gave you.

While we work

You watch it happen

From the day your book starts, your dashboard carries a live production tracker — every chapter and its status, the percentage complete, your manuscript on file, and the date we are working to. Chapters appear as they are finished, so you can listen to your book take shape rather than wait in silence for it.

It matters more here than on a human production. A synthetic voice can drift, mispronounce a name or lose the thread of a sentence, and you know your book better than anyone. If something reads wrong to you, flag it from the tracker and it goes on the fix list — logged, corrected and tracked to done, with no email chain.

Frequently asked

The questions that matter

Can I put this on Audible?

No. ACX, the route on to Audible, prohibits text-to-speech, AI and automated recordings. That is their rule, quoted on this page, and it applies whether the voice is a stock synthetic one or a clone of your own. Audible has said it is working towards accepting third-party synthetic speech, but has given no date.

If Audible matters to you, order human narration instead.

What happens if a platform rejects my audiobook?

You keep the files and we keep the fee. That is what the confirmation at the order step is about: the production is what you are buying, and it will have been delivered as ordered. We cannot control a retailer’s policy.

This is why we ask where you intend to sell it before you order, and why we will say so if the answer makes this product the wrong buy.

Can you clone my voice?

Yes, from a sample you supply and are entitled to use. You confirm that entitlement at the order step and it is recorded against your order. A cloned voice is still synthetic speech as far as a platform is concerned — it does not unlock Audible.

Is it as good as a human narrator?

No, and we are not going to tell you it is. A synthetic voice does not act, and it does not make choices about a line. What it does do is read your book accurately, in a consistent voice, for less money than a human production — once we have taken out the mistakes, fixed the pronunciation and mastered it.

What am I actually paying for?

A voice you chose — including a clone of your own — and the studio work that turns a raw generation into an audiobook: pronunciation corrected and regenerated, mistakes and nonsense cut, every chapter proofed against your manuscript, and the whole thing mastered to retail specification.

You also end up owning the files. They are yours, in full quality, to take to any platform that will accept them — not locked inside one shop’s system.

How long does it take?

The calculator gives you a working-day estimate from your start date: generation, editing, and a proofing pass. It is quicker than a human production because nobody has to book a narrator — but it is not instant, because the proofing is real.

Not sure this is the right product?

Tell us where you need the book to sell and we will tell you straight — including if the answer is human narration, or nothing at all.
