Claim 0:
1. A voice dialogue system, comprising:
a voice input unit configured to acquire user utterances of a user;
a dialogue text creator configured to create system utterances, wherein the dialogue text creator creates the system utterances based upon a stored history of dialogue performed in a past between the system and the user stored in a dialogue manager, the dialogue manager storing a time and date or location of the dialogue and enabling what kind of conversation had taken place with the user to be discerned and a response using previous dialogue as a reference to be generated;
a voice output unit configured to output the system utterances as voice data; and
a determiner configured to determine whether or not that the user utterance acquired by the voice input unit is a response to the system utterance currently being output as voice data, wherein
in response to a first system utterance output by the voice output unit and a second system utterance output after the first system utterance without having acquired a user utterance, the second system utterance comprising a connective portion for connecting following sentences and a content portion that is a subject of the second system utterance, the content portion including (a) a first content portion that is a first system utterance that is output before the connective portion and (b) a second content portion that is a second system utterance that is output after the connective portion, the first content portion is a first question and the second content portion is a second question different from the first question, the determiner determines:
that the user utterance is a response to the first system utterance when the user utterance is acquired during output of the connective portion of the second system utterance by the voice output unit, and
that the user utterance is a response to the second system utterance when the user utterance is acquired during output of the content portion of the second system utterance by the voice output unit.
