自律型アンドロイドErica のための音声対話システム

抄録

This paper gives an overview on the spoken dialogue system for autonomous android Erica developed in the JST ERATO Ishiguro human robot interaction project. In order to realize human-like behaviors, the system introduces a mixed-initiative dialogue management and generation of natural backchannels and noddings, assuming a part to play in a social interaction. Natural interaction with real users is achieved by quick response generation with suppression of incorrect language understanding and also reacting with non-verbal behavior when the system fails in speech recognition or language understanding.
