Abstract

Provided is a voice dialogue device that determines a state of a load on an occupant in a vehicle on the basis of at least one of the states such as a traveling state of the vehicle (100), an externalenvironmental state of the vehicle, and a state of the occupant in the vehicle, and utilizes a dialogue program corresponding to the state of the load on the occupant to dialogue with the occupant.

Description

technical field [0001] The invention relates to a voice dialogue device, a voice dialogue system and a control method of the voice dialogue device. Background technique [0002] A known dialogue device is mounted on a vehicle together with a sound output device for outputting sound into a vehicle interior, and can carry out a dialogue with a driver of the vehicle. and express the conversation text through the voice output device; the load determination unit determines whether the driving load of the driver is high for the road on which the vehicle is traveling; and the expression control unit determines that the driving load is high by the load determination unit Hereinafter, it is set to a prohibited state in which the dialogue realization unit is prohibited from starting expression, and when the load determination unit determines that the driving load is low, it is set to a permitted state in which the dialogue execution unit is allowed to start expression (Patent Document...
