Greta Listening to Expressive Music
In this page we
present an application in which the embodied
conversation agent Greta is listening to expressive music
performance. Starting from studies on the expressivity in Embodied
Conversational Agents (ECAs) and in music performance we developed a
system in which visual feedback of an acoustic source is given to the
user using a graphical representation of a human face.
expressive behavior of Greta depends on the emotional and
acoustic characteristics of the music performance she is listening
to. The system incorporates a previously developed system realized by
KTH Stockholm and Uppsala University for the real-time extraction and
analysis of acoustic cues from the music performance. It has been
interfaced with the ECA Greta developed at the University of Rome
``La Sapienza'' and University of Paris 8.
This project was originally started as
an interchange within the HUMAINE
