Effect of Politeness on Trust in Re-Enter Requests to User by Smart Speaker —Pilot Study—

When a smart speaker encounters an error, it frequently prompts the user to re-enter the input information. This study examines the psychological impact of adopting a politeness strategy, involving linguistic considerations, for re-enter requests with a smart speaker, particularly focusing on its effect on trust. Specifically, a video-based impression evaluation experiment was conducted to assess the impact of politeness in re-enter requests on improving trust in situations where the smart speaker failed to deliver the expected output for the user.
