After you click Add Voice and try to record your voice, if it doesn't work then you may have not granted us access to your computer's microphone.
The Chrome browser is required to narrate your book.
Here's what to do:
- In Chrome, in the URL bar, enter the following: chrome://settings/content/microphone
- In the Block section, click the garbage can icon to remove any lines that block access to "storyjumper.com"
Then try recording your audio again and grant "storyjumper.com" access to your microphone when prompted.
