Computer and Emotions, may soon be a reality

A computer character, capable of realistic emotional expressions may soon be incorporated into working applications.

The research team in the Information Society Technologies (IST) project ERMIS created a prototype able to analyse and respond to user input.

In the analysis phase, the team extracted some 400 features of common speech, then selected around 20-25 as the most important in expressing emotion. These terms were then fed into a neural network architecture that combined all the different speech, paralinguistic and facial communications features. For facial expression, some 19 were selected as the most relevant and were input accordingly.
