Work on spoken dialogue systems (SDS) has largely been dominated by “slot filling” applications for the past decade or more, where information-gathering tasks such as restaurant search and flight booking have been the main focus of research. An important class of dialogues, about planning and executing tasks, has correspondingly been somewhat neglected. However, planning and execution dialogues become very important when we consider Human-Robot Interaction (HRI), as does the ability to carry out “social” open-domain conversation. This paper describes a new architecture that supports complex multi-threaded task planning and execution dialogues, interleaved with “social” dialogue with an open-domain chatbot.
