To improve accessibility and usability of content, we use Amazon's Polly neural network service to convert finished text to a lifelike recording, which may be embedded and listened to on any chapter or article page.
This is a one-time cost. However, if the content is updated, then the fee will need to be paid again to update the recording to match the new text.
Example of a Page with Text-to-Speech
~$1 per chapter (per conversion); actual costs will be calculated based on the number of characters
If you would like to remove the text-to-speech file or prevent it from showing on the chapter, delete the content of the "External Audio" field in the chapter Settings. You can also replace the content of this field with a link to another fully-qualified URL, if you have a different recording you would like to use.
