Expressive avatars are our AI avatars that deliver scripts like real actors. They match the sentiment of your text using tone of voice, facial expressions, gestures, and accurate lip-syncing — making your videos feel more human and engaging.


What makes them expressive?

Each expressive avatar is paired with an expressive voice, available in 28 languages. The emotion they show depends entirely on your script.


Tips to bring emotion to your script

  • Use expressive words: e.g., “Fantastic!”, “Great job!”

  • Add punctuation: Exclamation marks, question marks, and ellipses help shape tone

  • Try simple emoticons: :) or :( can trigger subtle emotional cues


How to find expressive avatars

Look for the purple star icon in the avatar or voice selection menus.
