Abstract: A dialog device according to an embodiment includes an acquisition unit configured to acquire a user utterance input by a user, a plurality of generation units configured to generate a system utterance corresponding to the user utterance, and an output unit configured to output the system utterance generated by one generation unit selected from the plurality of generation units. The plurality of generation units include a first generation unit having a first scenario and a second generation unit having a second scenario different from the first scenario. The output unit outputs a first system utterance generated by the first generation unit in response to the user utterance, in a first expression format, and outputs a second system utterance generated by the second generation unit in response to the user utterance, in a second expression format different from the first expression format, following the first system utterance.

Abstract: An interaction apparatus 10 includes an acquiring unit 13 for acquiring a system message, a setting unit 14 for setting a wait time for receiving an answer from a user based on the system message, a measuring unit 16 for measuring an elapsed time after the system message is output to the user, a user utterance acquiring unit 15 for acquiring a user utterance, and a controller 17 for controlling an interaction with the user so that an additional action corresponding to the system message is output to the user. The measuring unit 16 determines 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 by the user utterance acquiring unit 15 after the system message is output.
