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.
Greta currently speaks various languages: English, Italian, French, German, Swedish and Polish.
A chat bot is a humanlike conversational character.
Its conversational skills and other humanlike behaviour is simulated through artificial intelligence.
It often acts as a virtual assistant and it can have its own visualisation through an avatar
or it is faceless. We expect that through the years every conversational chat bot will grow into a real virtual human.
