Abstract: A voice dialogue system includes: a voice input unit which acquires a user utterance, a dialogue text creator which creates a text of a system utterance, a voice output unit which outputs the system utterance as voice data, and a setting unit that sets a response deadline for system utterances. 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 setting unit sets a timing at which output of the connective portion of the second system utterance ends or output of the content portion of the second system utterance starts as the response deadline for the first system utterance.

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.

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.

Abstract: A voice dialog device includes a sight line detection unit configured to detect a sight line of a user, a voice acquiring unit configured to acquire voice pronounced by the user, and a processor. The processor is configured to perform a step of acquiring a result of recognizing the voice, a step of determining whether or not the user is driving, and a step of determining whether or not the voice dialog device has a dialog with the user. When the detected sight line of the user is in a certain direction, and a start keyword has been detected from the voice, the processor determines that the user has started a dialog. The processor switches the certain direction based on whether the user is driving.

Abstract: A keyword generation apparatus, comprises a vocabulary acquisition unit that acquires a keyword uttered by a first user; a first positional information acquisition unit that acquires first positional information including information representing a location at which the first user has uttered the keyword; a storage unit that stores the first positional information and the keyword in association with each other; a second positional information acquisition unit that acquires second positional information including information representing a current position of a second user; and an extraction unit that extracts a keyword unique to a locality in which the second user is positioned from the storage unit based on the second positional information.

Abstract: A voice interactive device that interacts with a user by voice, the device comprises a voice input unit that acquires and recognizes voice uttered by a user; a degree-of-intimacy calculating unit that calculates a degree of intimacy with the user; a response generating unit that generates a response to the recognized voice, based on the degree of intimacy; and a voice output unit that outputs the response by voice, wherein the degree-of-intimacy calculating unit calculates a degree of intimacy with the user based on a sum of a first intimacy value calculated based on a content of an utterance made by the user and a second intimacy value calculated, based on the number of previous interactions with the user.

Abstract: A voice dialogue system includes a dialogue scenario storage storing a plurality of dialogue scenarios and a dialogue text generator generating a dialogue text for responding to a user utterance based on a result of voice recognition. The dialogue scenario is a single set of three contents: a content of a first system utterance, a content of an expected user utterance, and a content of a second system utterance for responding to the expected user utterance. The dialogue text generator determines whether or not the user utterance is an expected response and, when the user utterance is an expected response, generates a second system utterance defined in a dialogue scenario as a response to the user utterance as a dialogue text for responding to the user utterance.
