Realizing Multilingual Interactive Agents through Wizard of Oz

Abstract

Interactive agents are expected to play essential roles in many fields. Moreover, it is becoming more and more important for interactive agents to deal with multilingual issues because of globalization. In this paper, we aim at realizing a multilingual interactive agent that can support end users in various fields. To achieve this goal, we first propose a framework for the multilingual interactive agent that can support dialogues with end users through Wizard of Oz. We then propose the approach of gradual acquisition of multilingual dialogues to improve the performance of the interactive agent. Moreover, we apply the proposed framework and implement a multilingual interactive agent in the field of healthcare.
