Abstract

The study aim to test the effect of voice agent's preceding utterance type on the user experience in the smart home contexts by conversation types. Based on two types of conversation (task-oriented vs. relationship-oriented conversations) and two types of utterance (preceding vs. response utterances), four different scenarios were designed for experimental study. A total of 62 participants were divided into two groups by utterance type, and exposed to two scenarios of the conversation types. Likeability, psychological reactance, and perceived intelligence were measured for the user experience of conversational agent. The result showed main effects of likeability in task-oriented conversations, and of psychological reactance in preceding utterances. The interaction effect demonstrated that preceding conversation improved the likeabilitty and perceived intelligence in the task-oriented conversations.

이 연구는 스마트 홈 환경에서 대화 주제 유형에 따라 음성 에이전트의 선행 발화 방식이 사용자 경험에 미치는 효과를 확인하고자 하였다. 과제 중심적 대화와 관계 중심적 대화의 두 가지 대화 유형을 바탕으로, 스마트 스피커의 발화 방식을 선행 발화와 후행 발화로 구분하여 네 가지 시나리오를 제작하였다. 온라인 실험을 진행하여 총 62명의 참가자를 발화 방식에 따라 두 그룹으로 나누어, 대화 유형의 두 가지 시나리오를 진행하게 하고, 호감도, 심리적 저항감, 지각된 지능의 사용자 경험 요인을 측정하였다. 실험 결과, 대화 유형 중 과제 중심적 대화에서 호감도의 주효과가 나타났고, 발화 방식에서 선행 발화에 대한 심리적 저항감의 주효과가 나타났다. 선행 발화 방식은 과제 중심적 대화에서 호감도와 지각된 지능을 높이는 효과를 보였다.
