• and
• a speech determination part that obtains, where the recognition result of the desired level corresponding to the user speech is not obtained, a speech which does not include any content words as a first agent speech which is a speech of the agent uttered immediately after the user speech, and generates or selects a speech not based on the user speech as a second agent speech, which is a speech of an agent which is different from the agent uttered after uttering the first agent speech, wherein the speech determination part generates or selects a speech associated with at least part of at least one of a speech uttered by the user before the user speech to which the dialog apparatus cannot obtain any recognition result of the desired level corresponding and a speech uttered by the agent before the user speech to which the dialog apparatus cannot obtain any recognition result of the desired level corresponding, as the second agent speech.
