If your book has a Kindle book version, you can use ACX to produce a digital audiobook version of your book, and to make your book eligible for the new Whispersync for Voice functionality which allows customers to switch seamlessly between reading a Kindle book and listening to the corresponding, professionally narrated audiobook across devices without losing their place. Audiobooks will also be eligible for the new Immersion Reading feature, which allows customers with the new Kindle Fire and Kindle Fire HD devices to listen to a professionally narrated audiobook from Audible as the text of the corresponding eBook is highlighted on the screen. When customers buy your Kindle book, they will be able to purchase your Whispersync for Voice-ready Audible audiobook at a special limited time discounted price.
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. Currently, your title must also be written and narrated in English.
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 Audible.com, you can contact our client support team to discuss Whispersync for Voice and Immersion Reading.
Audible attempts to sync all eligible books as they become available, within one month of their release date. Normal processing times vary, and titles that fail to pass our sync quality standards experience longer processing times as we investigate the issue.
Once your eligible title goes live, it will be added to the queue of titles awaiting processing, where we sync the matching Kindle book to your audiobook. There are a number of reasons why your title may not already be enabled, including but not limited to technical challenges and discrepancies between the Kindle and audiobook content. While we cannot guarantee that your book will be enabled for Whispersync for Voice, you may send a request to our processing team for more information by emailing email@example.com.
With more than 150,000 titles in our store and new ones releasing daily, we are constantly working to enable eligible titles. To confirm that your titles are queued for syncing, please email firstname.lastname@example.org.
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 client support team to alert them. Some changes including margin size, font color, font size, background color, and minor punctuation updates may not impact the features.
Because you've made a change to your audiobook file, we will need to reprocess your title for Whispersync for Voice to ensure that the content still syncs properly. This reprocessing can take up to a week. However, if the changes to your audiobook are content-related and the resulting audio file no longer syncs well with the Kindle version of your book, your title may lose Whispersync for Voice eligibility.
Whispersync for Voice is a feature Audible proudly offers to customers, and it cannot be disabled. Whispersync for Voice adds value to a customer's reading experience and raises awareness for an author's titles by linking the Audible edition to the Kindle edition.
When we process your audiobook for Whispersync for Voice, we're looking to match up the Kindle and audiobook content as closely as possible. Inevitably, there will be differences between the two versions, so we try to accommodate front and back matter as best we can. The syncing between the two formats should start with the first word after front matter (table of contents, dedication, etc.) and end with the last word of the last chapter.
Currently, Whispersync for Voice only supports Latin characters. If we are unable to match the content between formats, the title will not be eligible for Whispersync for Voice.
Because customers first purchase the Kindle edition of a title before adding the Whispersync for Voice audio, they are offered a special reduced price for the digital audio add-on to incent them to buy two formats of the same title. Reduced prices for our Whispersync for Voice audio typically range from $1.99 to $12.99.
