  This paper describes the dialog robot system designed by Team Irisapu for the
preliminary round of the Dialogue Robot Competition 2023 (DRC2023). In order to
generate dialogue responses flexibly while adhering to predetermined scenarios,
we attempted to generate dialogue response sentences using OpenAI's GPT-3. We
aimed to create a system that can appropriately respond to users by dividing
the dialogue scenario into five sub-scenarios, and creating prompts for each
sub-scenario. Also, we incorporated a recovery strategy that can handle
dialogue breakdowns flexibly. Our research group has been working on research
related to dialogue breakdown detection, and we incorporated our findings to
date in this competition. As a result of the preliminary round, a bug in our
system affected the outcome and we were not able to achieve a satisfactory
result. However, in the evaluation category of "reliability of provided
information", we ranked third among all teams.
