What you can create

Begin with a portrait

Choose the image you want to animate. Use a clear view of the face so you can inspect the result.

Provide the spoken audio

Add the recording that your portrait should speak. Listen to the audio first and confirm that the words sound right.

Guide gestures with a description

Optionally describe how the avatar should move. Keep the requested gestures suitable for the portrait and the spoken message.
