GRETA: Embodied Conversational Agent

Greta is a real-time three dimensional embodied conversational agent with a 3D model of a woman compliant with MPEG-4 animation standard. She 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 SAIBA architecture.

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

Greta is used in various European projects: ILHAIRE, VERVE, REVERIE, TARDIS, SSPNet and national French projects: Feder Anipev, ANR IMMEMO, ANR CECIL, GV-LEx.
