Abstract
A dialogue service device includes a dialogue system control unit configured to recognize an occupant's voice and control a dialogue system that interacts with the occupant in order to provide a service, and an activation unit that activates the dialogue system. The dialogue system includes a first dialogue system having a first voice recognition engine, and a second dialogue system having a second voice recognition engine. The activation unit has a first interface that outputs an activation command to the dialogue system via operation of a steering wheel switch of the vehicle, and a second interface that outputs the activation command to the dialogue system via a wake-up word uttered by the occupant. The first interface transmits the activation command to the first dialogue system, and the second interface transmits the activation command to either the first dialogue system or the second dialogue system.
