Audiobook Production with ACX

Can I choose the narrator?
Yes, you can choose the narrator. (Note: on ACX, narrators are generally referred to as "Producers" because they not only narrate the audio version of your book, but they produce a retail-ready audiobook). You can search the ACX website for the perfect narrator/producer, or wait for ACX narrators/producers to audition for your audiobook project. You will also be involved in the audiobook production, approving it at various points along the way.

Can I narrate my own audiobook?
We find that most audiobooks are best performed by professional actors, but it is possible for you to narrate your own audiobook.

I live outside of the US and cannot provide a W9. Is ACX open to me?
At this time, ACX is open only to residents of the United States and United Kingdom who have a US or UK mailing address, and a valid US or UK Taxpayer Identification Number (TIN). For more information on Taxpayer Identification Numbers (TIN), please visit the IRS website. We hope to increase our availability to a more global audience in the future.

Royalty and Distribution:

What is the audio distribution and royalty that I will get?
ACX  distributes your audiobook to,, and iTunes, the three leading retailers of audiobooks, as well as their global retail partners. Your  royalty is dependent upon the distribution and production options you select.  If you choose to distribute exclusively to these three channels, you will earn  40%. However, if you choose to produce the audiobook using the Royalty Share  option, you will earn 20%. If you choose to distribute your audiobook  non-exclusively, you will earn 25% and retain the right to distribute your  recording at your discretion. More information is available here.

Where will my finished audiobook be sold?

How do I get paid for my audiobook sales?
You may  choose to receive monthly royalties via check or by direct deposit to the  account of your choice. You'll get a monthly statement from ACX, which will  include unit sales numbers from sales on,, and iTunes.  Along with the statement, if sales are more than $50 per period, you will  receive a corresponding royalty payment.

Why is the upgrade price for my digital audiobook for customers who buy the Kindle version different than the a la carte price for my digital audiobook – and how are these prices set?
We want to encourage people who have purchased a Kindle book to try the new Whispersync for Voice and Immersion Reading features, so prices for this digital audiobook upgrade are generally lower than purchasing the audiobook a la carte.

Enabling Audiobook for Whispersync for Voice and Immersion Reading

How can I create a digital audiobook version of my book and make it eligible for Whispersync for Voice and Immersion Reading?
The basic technical  requirement that your audiobook must meet to qualify for Whispersync for Voice is a nearly perfect sync rate between the Kindle and audiobook content. Your audiobook must also be unabridged. For more information, visit ACX.

My book is already produced in digital audiobook format and available at How can it be made eligible for Whispersync for Voice and Immersion Reading?
Currently not all books are enabled for these new features, but the Audible team is working to increase the number of books enabled. If your book is already available on, you can contact Audible's customer care team to discuss Whispersync for Voice and Immersion Reading.

How are Whispersync for Voice and Immersion Reading different than the current text-to-speech Kindle feature?
There are several differences between these features – a full description of each can be found at Millions of customers who already use Audible know how wonderful it is to listen to a book narrated by the author or performed by a skilled actor.

How long will it take to produce my book and enable it for Whispersync for Voice and Immersion Reading?
From the time you start the production process, we estimate that it will take about 6 to  12 weeks to complete the audiobook, depending on the length of the book and the  Producer's schedule. Once the finished audiobook is approved by you, it typically takes up to 14 business days to get the audiobook into stores. The  work done during this time ensures that the audiobook is recorded correctly and  ready for retail distribution, and attempts to enable it for Whispersync for  Voice and Immersion Reading.

How can I make sure my Kindle book and audiobook are able to sync?
We need  the narrated words to perfectly mirror the words in the Kindle book to be  eligible for the Whispersync for Voice program. Here is some general advice for  both you and the audiobook's producer to ensure your production has the best  chance of being made eligible:

  • Avoid ad-lib in narration.
  • Make sure the audiobook is edited well and sentences are not inserted twice (e.g. editor leaves in duplicate actor takes of the same sentence).
  • Do not add  audio content that isn't in the Kindle version. If there is a chapter of audio  that isn't in the Kindle book, often it's not  sync-able.
  • Avoid background music; music in the audiobook reduces the likelihood that it will be sync-able.
  • Do not have the narrator read footnotes "in line."
  • Do not describe figures or photographs when the description isn't in the actual text of the Kindle book.
Furthermore, if  you make changes to your Kindle book, such changes may cause the two products  to be unsync-able (inside the book, this includes inserting or rewriting  sentences, paragraphs, or chapters). If you make any significant changes, the  two products will not be sync-able. Some changes including margin size, font  color, font size, background color, and minor punctuation updates may not  impact the features. Also, metadata changes will not impact the features  (price, title, author, product description, etc.).

Can I still make updates to the Kindle version of my book or will that impact the Whispersync for Voice and Immersion Reading features?
Metadata changes to your book will not impact the features (price, title, author, product description, etc.). Changes made inside your Kindle book may impact the Whispersync for Voice and Immersion Reading features. However, if you are alerted about formatting issues with your Kindle book, we recommend that you correct those issues. When you make these changes, your book will not by sync-able immediately. If it remains un-synced for more than 1 week, we suggest that you contact the ACX customer care team to alert them. Some changes including margin size, font color, font size, background color, and minor punctuation updates may not impact the features.

KDP Select:

If my book is in KDP Select and available in the Kindle Owners Lending Library (KOLL), will people who borrow my book through KOLL be able to purchase the digital audiobook at the upgrade price?
No, only purchases of Kindle books qualify for the audiobook upgrade discount. If a customer has borrowed a Kindle book through KOLL, they are not eligible to the discounted price at Audible. Those discounts are tied to purchases only.

Will people who download my book for free during my KDP Select free promotion days be able to purchase the digital audiobook at the upgrade price?
Yes, they will be able to get the audiobook at the discounted upgrade price if they have bought the Kindle book, even if the price of the Kindle book is $0.
