  • Patent number: 11295742
    Abstract: In a voice output apparatus, an acquisition unit acquires a speech of an occupant of a vehicle. A determination unit determines whether or not the acquired speech is asking for repetition or rephrasing. A classification unit classifies, when it is determined that the speech is the asking, the speech according to a type of asking. An output unit outputs a voice sound in accordance with the classified type of the asking based on a content of a voice sound that is a target of the asking.

  • Patent number: 11280917
    Abstract: An information processing system includes a server and a first vehicle acquiring a combination of first and second position information of the first vehicle. The first position information is calculated using a positioning signal from the first satellite system. The second position information is obtained by correcting an error of the first position information using a positioning reinforcement signal from the second satellite system. The first vehicle or the server calculates difference information between the first and second position information for each combination thereof. The server estimates a calculation accuracy for the first position information in a road section on a road map based on one or more pieces of difference information in which one or more positions indicated by the second position information corresponding to the difference information are within the road section and to output the calculation accuracy for the first position information in the road section.

  • Patent number: 11189048
    Abstract: An information processing system includes a vehicle, and a server configured to communicate with the vehicle. The vehicle generates a captured image of scenery outside the vehicle. The vehicle or the server: starts a first detection processing of successively detecting a first subject in the captured image; determines, as a target region, a partial region of the captured image including a prescribed number of first subjects when the prescribed number of the first subjects are detected; terminates the first detection processing of the target region; and performs image processing of lowering visibility of an image on the target region. The server then transmits the captured image subjected to the image processing to a transmission destination other than the vehicle.
