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.

Determining a current system utterance with connective and content portions from a user utterance

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.

Determining a system utterance with connective and content portions from a user utterance

Described is a voice dialogue system that 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.

A system comprises an apparatus having a first voice I/O device; and a voice interface apparatus having a second voice I/O device, and connected to the apparatus by audio connection via short-range wireless communication, wherein the apparatus includes a voice I/O unit that performs voice input and output by using the first voice I/O device or the second voice I/O device; an interaction unit that performs voice interaction with a user; and a process unit that performs a process other than the voice interaction, by using the voice I/O, and the voice I/O unit switches a device used for the voice input and output to the first voice input/output device in a case where the process unit is brought into a first state in which the voice input and output is required when the voice interaction with the user is performed by using the second voice I/O device.

Voice interaction system and information processing apparatus

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.

A voice interactive robot interacting with a user by voice includes a main body, a movable part capable of moving relative to the main body, a following control unit that moves the movable part so that the movable part follows the user, a temporary origin setting unit that sets a temporary origin of the movable part in response to movement of the movable part by the following control unit, an acquisition unit that acquires an operation instruction issued in relation to the movable part, and an operation execution unit that moves the movable part in accordance with the operation instruction using the temporary origin as a reference.

Voice interactive robot and voice interaction system

A voice interaction system includes: a speaker; a microphone having a microphone gain that is set at a low level while a sound is output from the speaker; a voice recognition unit that implements voice recognition processing on input sound data input from the microphone; a sound output unit that generates output sound data and outputs the generated output sound data through the speaker; and a non-audible sound output unit that, when a plurality of sounds are output with a time interval no greater than a threshold therebetween, outputs a non-audible sound through the speaker at least in the interim between output of the plurality of sounds.

A decision making support device including: an opinion acquiring module that acquires an expressed opinion from each of a plurality of participants with respect to each of the plurality of selective elements; and a target person determining module that determines, with respect to a given selective element, from which participant an opinion on the selective element is to be elicited when there are a plurality of unexpressed participants who have not yet expressed opinions on the selective element, wherein the target person determining module respectively calculates, when assuming that each of the unexpressed participants has expressed any of expected opinions, assumed group satisfaction that is determined based on contents of decision making and contents of expression of opinions of the plurality of participants, and determines from which participant an opinion on the selective element is to be elicited in consideration of the assumed group satisfaction.

Decision making support device and decision making support method

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.

Keyword generation apparatus and keyword generation method

A route search apparatus configured to search a route from a set place of departure to a set destination comprises network data that includes nodes and links representing a road network, an average cost value indicating an average of travel time of each of the links, and a variance value indicating a degree of variance of the travel time, and a route searcher configured to determine the route from the place of departure to the destination as a recommended route, based on the average cost value, the variance value and a weight coefficient of the variance value.
