Dialog method, dialog system, dialog apparatus and program

A dialog system comprising:

• a speech receiving part that receives input of a speech of a human;
• a first speech determination part that determines a first speech which is a speech in response to the speech of the human;
• a first agent that presents the first speech;
• a reaction acquisition part that acquires a reaction of the human to the first speech;
• a second speech determination part that determines, when the reaction of the human is a reaction indicating that the first speech is not a speech in response to the speech of the human, a second speech which is a speech different from the first speech;
• and
• a second agent that presents the second speech,
• wherein the second speech is (A) a speech which expresses that the first speech has caused a failed speech or suggests a possibility that the first speech might have caused a failed speech or (B) a speech which is accompanied by a topic changing word and relates to the speech of the human instead of the first speech.

A dialog apparatus comprising:

• a first speech determination part that determines a first speech which is a speech in response to an inputted a speech of a human and is a speech presented by a first agent;
• and
• a second speech determination part that determines, when a reaction of the human to the first speech is a reaction indicating that the first speech is not a speech in response to the speech of the human, a second speech which is a speech different from the first speech and is a speech presented by a second agent,
• wherein the second speech is (A) a speech which expresses that the first speech has caused a failed speech or suggests a possibility that the first speech might have caused a failed speech or (B) a speech which is accompanied by a topic changing word and relates to the speech of the human instead of the first speech.

A dialog method performed by a dialog system, the dialog method comprising:

• a speech receiving step in which the dialog system receives input of a speech of a human;
• a first speech determination step in which the dialog system determines a first speech which is a speech in response to the speech of the human;
• a first speech presentation step in which the first speech is presented by the dialog system;
• a reaction acquisition step in which the dialog system acquires a reaction of the human to the first speech;
• an action determining step in which the dialog system determines, when the reaction of the human is a reaction indicating that the first speech is not a speech in response to the speech of the human, action contents which are contents of actions of expressing that the first speech is not a speech in response to the speech of the human;
• and
• an action step in which the dialog system performs an action with the action contents,
• wherein the dialog system comprising a first agent and a second agent,
• in the first speech presentation step, the first speech is presented by the first agent,
• the action contents indicates contents of a second speech which is a speech expressing that the first speech is not a speech in response to the speech of the human, and
• the action with the action contents is an action where the second speech is presented by the second agent.

• and
• an action step in which the dialog system performs an action with the action contents,
• wherein the dialog system comprising a first agent and a second agent,
• in the first speech presentation step, the first speech is presented by the first agent,
• the action contents indicates contents of a second non-language communication which is a non-language communication expressing that the first speech is not a speech in response to the speech of the human, and
• the action with the action contents is an action where the second agent performs the second non-language communication.
