なぜAIスピーカからの発話はよそよそしいのか？： 親近感を生みだす「あれ」の役割

摘要

街中でふと耳をすますと「いつものあそこ集合で！」といった発話が聞こえてくる．聞き手もそれに続けて，「あそこな！」「あそこってどこだっけ？」と仲睦まじく繋がる会話を聞いていると，当事者間の関係性などが見えてくる．こういった発話は，日常での友達同士や同僚間の会話でよく見かけることが多い．私たちの日常での会話は，このような当事者間の関係性をお互いが理解し，それを前提に発話や応答をすることが一般的である．%In intimate relationships, structurally insufficient statements, such as"Tomorrow's gathering is at that place!" would be sufficient semantically for the parties to understand each other. On the other hand, considering the statements of AI speakers, they convey information accurately without excessiveness or insufficiency; therefore, it is difficult to emerge intimacy in the interaction between an AI speaker and its interlocutor. In this presentation, we discuss an interaction design for an AI speaker which can create a sense of intimacy by using the "common ground"as a clue that is built during a conversation between the AI speaker and its interlocutor.
