When a vehicle information acquisition unit continuously acquires an On signal of a blinker switch, when the absolute value of a steering angle of a handle is 90° or greater, and a vehicle speed is a threshold or greater, a dialogue confirmation unit of this vehicle communication device selects a dialogue that corresponds to the On signal, the steering angle, and the vehicle speed from dialogues of group A stored in a dialogue storage unit. Thereafter, when the steering angle or the vehicle speed changes, the dialogue confirmation unit selects the dialogue that corresponds to changes in the steering angle or the vehicle speed from among dialogues of group.
