What is Greta

What is Greta

Greta is a real-time three dimensional embodied conversational agent with a 3D model of a woman compliant with MPEG-4 animation standard. It is able to communicate using a rich palette of verbal and nonverbal behaviours. Greta can talk and simultaneously show facial expressions, gestures, gaze, and head movements.

Two standard XML languages FML and BML allows the user to define her communicative intentions and behaviours based on standard architecture.

For architecture detail:

• Core (SAIBA, FML, BML)
• Relative behavior (outdated, for reference use only, not supported anymore)

Greta can be used with different external TTS softwares. Currently she can speak various languages: English, Italian, French, German, Swedish and Polish.
