How to Use Orion Voices for Your Books

Once you have set up the Orion Engine, you can easily set it as the default voice for any book. This allows you to generate audio for offline listening or stream the voice in real-time.

Setting Orion as the Default Engine for a Book

1. Open Your Book: Go to your Library and tap on the book you want to listen to.

2. Open Voice Settings: In the book's player or details screen, tap the Voice Settings (or Voice+/Gen AI) icon.

3. Select the Engine: Look for the TTS Engine (or Active Engine) dropdown menu.

4. Choose Orion: Select Orion from the list of available engines.

Generate or Play

Generate Audio (Offline)

Tap Generate Audio if you want to process the book entirely offline so it is saved directly on your device for future listening without an internet connection.

Stream (Real-time)

Or, simply hit the Play button to have Orion stream the audio in real-time as you read along with the text.
