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: An information processing apparatus determines, when detecting an instruction from a user to search for a facility, whether position information of the user indicates that the user is in a first area where visit frequency of the user is higher than a predetermined threshold. The information processing apparatus detects, when the position information of the user indicates that the user is in a first area, a new facility by searching within a predetermined range based on the position information, and outputs the information about the detected new facility to a predetermined device. The information processing apparatus records, as the first area, an area where a visit frequency indicated by movement history information indicating movement history of the user is equal to or greater than a predetermined threshold.

Abstract: 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.

Abstract: An information output control method includes a step of deriving a driving load of a driver, based on a traveling environment or a driving state of the driver, a step of deciding to suggest a content that meets the derived driving load, to the driver, and a step of calculating a degree of acceptance of the suggested content by the driver. In the deciding step, the frequency of suggestion of the content or the type of the content is set based on the calculated degree of acceptance.
