Abstract

A voice dialogue system includes: a voice input unit which acquires a user utterance; an intention understanding unit which interprets an intention of utterance of a voice acquired by the voice input unit; a dialogue text creator which creates a text of a system utterance; and a voice output unit which outputs the system utterance as voice data, wherein when creating a text of a system utterance, the dialogue text creator creates the text by inserting a tag in a position in the system utterance, and the intention understanding unit interprets an utterance intention of a user in accordance with whether a timing at which the user utterance is made is before or after an output of a system utterance at a position corresponding to the tag from the voice output unit.

Claims11

Dependent claims

A voice dialogue system, comprising:

a voice input unit configured to acquire user utterances;
a dialogue text creator configured to create system utterances;
a voice output unit configured to output the system utterances as voice data;
and
a determiner configured to determine whether or not a current user utterance acquired by the voice input unit is a response to a current system utterance when the current user utterance is acquired while the current system utterance is being output as voice data, wherein
the current system utterance comprises a connective portion for connecting following sentences and a content portion that is a subject of the current system utterance,
the determiner determines, when the current user utterance is acquired by the voice input unit after the output of the content portion of the current system utterance has started, that the current user utterance is a response to the current system utterance, and
the determiner determines, when the current user utterance is made is before the output of the content portion of the current system utterance has started, that the current user utterance is a response to a previous system utterance.

A voice dialogue system, comprising:

a voice input unit configured to acquire user utterances;
a dialogue text creator configured to create system utterances;
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
when a first system utterance is output by the voice output unit, a second system utterance is output after the first system utterance without having acquired a user utterance, and the second system utterance comprises a connective portion for connecting following sentences and a content portion that is a subject of the second system utterance, the determiner determines:
that a 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 a 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.
