  Although many competitions have been held on dialogue systems in the past, no
competition has been organized specifically for dialogue with humanoid robots.
As the first such attempt in the world, we held a dialogue robot competition in
2020 to compare the performances of interactive robots using an android that
closely resembles a human. Dialogue Robot Competition 2022 (DRC2022) was the
second competition, held in August 2022. The task and regulations followed
those of the first competition, while the evaluation method was improved and
the event was internationalized. The competition has two rounds, a preliminary
round and the final round. In the preliminary round, twelve participating teams
competed in performance of a dialogue robot in the manner of a field
experiment, and then three of those teams were selected as finalists. The final
round will be held on October 25, 2022, in the Robot Competition session of
IROS2022. This paper provides an overview of the task settings and evaluation
method of DRC2022 and the results of the preliminary round.
