Spoken dialogue system for a human-like conversational robot ERICA

Abstract

This article gives an overview of our symbiotic human-robot interaction project, which aims at an autonomous android who behaves and interacts just like a human. A conversational android ERICA is designed to conduct several social roles focused on spoken dialogue, such as attentive listening (similar to counseling) and job interview. Design principles in developing these spoken dialogue systems are described, in particular focused on the attentive listening system. Generation of backchannels, fillers and laughter is also addressed to make human-like conversation behaviors.
