1. An interaction apparatus comprising:
processing circuitry configured to
acquire a system message for a user;
set a wait time for receiving an answer from the user based on the system message;
measure an elapsed time after the system message is output to the user;
acquire a user utterance uttered by the user; and
control an interaction with the user so that an additional action corresponding to the system message is output to the user when the measured elapsed time exceeds the wait time,
wherein the processing circuitry is configured to determine whether or not to subtract the elapsed time, based on the system message and the user utterance, when the user utterance not corresponding to the answer to the system message is acquired after the system message is output.
