Over the past few years we have been develo** an expressive embodied conversational
agent system. In particular, we have developed a model of multimodal behaviours that …

Perception and expression of emotion are key factors to the success of dialogue systems or
conversational agents. However, this problem has not been studied in large-scale …

A key goal in agent research is to be able to generate multimodal characters that can reflect
a particular personality. The Big Five model of personality provides a framework for codifying …

This paper examines the effects of reduced speech bandwidth and the μ-low companding
procedure used in transmission systems on the accuracy of speech emotion recognition …

Social Signal Processing is the research domain aimed at bridging the social intelligence
gap between humans and machines. This paper is the first survey of the domain that jointly …

Pedagogical agent research seeks to exploit Reeves and Nass's media equation theory,
which holds that users respond to interactive media as if they were social actors …

There is a fundamental problem with the Turing Test (Turing, 1950). It is designed to help
decide whether a machine has genuine intelligence comparable to that of a human, and …

This paper describes a real-time Speech Emotion Recognition (SER) task formulated as an
image classification problem. The shift to an image classification paradigm provided the …

Emotional conversation generation has elicited a wide interest in both academia and
industry. However, existing emotional neural conversation systems tend to ignore the …

In this article, we propose a new set of acoustic features for automatic emotion recognition
from audio. The features are based on the perceptual quality metrics that are given in …
