Abstract: A server for controlling an output of a sound from a sound output device provided in a room of a destination of a moving user, the server including: an information acquiring section configured to acquire position information indicating a position of the user, the destination, and route information indicating a route of the user to the destination; and a control section configured to, in a case in which the user reaches a position within a predetermined range from the destination, control the sound output device to start the output of a sound that simulates a situation in which a person is present in the room based on the position of the user indicated by the position information and the route of the user indicated by the route information.

Abstract: A voice output device is provided that includes an acquisition unit that acquires a vehicle state and an output unit that, in a case in which the vehicle state acquired by the acquisition unit indicates an abnormality in the vehicle, outputs a sound associated with the vehicle state.

Abstract: A communication system includes a pair of speech recognition devices that are capable of communicating with each other, each of the speech recognition devices including a speech input section into which speech is input, a speech recognition section that recognizes speech input to the speech input section, and a speech output section that outputs speech. The communication system also includes an information generation section that generates notification information corresponding to speech recognized by the speech recognition section in one speech recognition device from out of the pair of speech recognition devices, and a speech output control section that performs control to output notification speech corresponding to the notification information at a specific timing from the speech output section of the other speech recognition device from out of the pair of speech recognition devices.

Abstract: A speech output device includes: an acquisition section configured to acquire information held by an appliance regarding contents inside the appliance; and an output section configured to output speech according to the information acquired by the acquisition section from a speech output section.

Abstract: A vehicle sound output device including: an acquiring section configured to acquire wakefulness level information that indicates a degree of a wakefulness state of a driver of a vehicle; and a control section configured to, in a case in which the degree of the wakefulness state indicates a decreased level of wakefulness, control a sound output section to output a sound based on at least one of a predetermined frequency, a predetermined tone, or a predetermined content that stimulates a sympathetic nerve of the driver.

Abstract: A speech interaction device includes an ascertaining section and a control section. The ascertaining section ascertains a direction of a speech utterer by audio emitted by the speech utterer. The control section controls directionality of audio output through a speaker when outputting audio toward the speech utterer, such that directionality of audio in the direction ascertained by the ascertaining section is higher than directionality of audio in other directions.

Abstract: A server for controlling an output of a sound from a sound output device provided in a room of a destination of a moving user, the server including: an information acquiring section configured to acquire position information indicating a position of the user, the destination, and route information indicating a route of the user to the destination; and a control section configured to, in a case in which the user reaches a position within a predetermined range from the destination, control the sound output device to start the output of a sound that simulates a situation in which a person is present in the room based on the position of the user indicated by the position information and the route of the user indicated by the route information.

Abstract: An information processing device is provided that includes (i) an acquisition unit that can acquire utterances from plural passengers who are on board a vehicle, (ii) a recognition unit that, in a case in which an utterance is acquired by the acquisition unit, recognizes one of the passengers who emitted the utterance, and (iii) a control unit that controls driving operation of the vehicle indicated by the utterance from the passenger, based on a recognition result of the passenger who emitted the utterance, the recognition result being obtained by the recognition unit, and setting information that is information having been set in advance with respect to each of the plural passengers and that is information about whether or not the passenger is a passenger who is permitted to perform the driving operation of the vehicle.

Abstract: A vehicle control device includes: a speech acquiring section that acquires speech data related to a speech of a speaker; a state acquiring section that acquires information indicating whether or not a driver attempting to start driving a vehicle is in an intoxicated state based on the speech data; and a control section configured to limit a start operation of the vehicle in a case in which the information indicates that the driver is in the intoxicated state, the start operation being an operation performed by the driver with respect to the vehicle to start driving the vehicle.

Abstract: Each of plural dialogue devices generates proposition information that is an utterance indicating a proposition for passengers who are on board plural vehicles, based on an utterance submitted by a passenger and current destination information and past destination information. The dialogue device transmits the generated proposition information to other dialogue device.

Abstract: A sound outputting device includes: a receiving section that receives driving information that supports driving of a moving body; a sound outputting section that outputs at least one of a musical piece currently playing or a voice that gives notice of the driving information; and an outputting section that, during playing of the musical piece, causes the sound outputting section to output the voice that gives notice of the driving information received by the receiving section so as to match at least one of a pitch or a tune of the musical piece that is currently playing.
