1. A hub for supporting a voice relay between wearable terminals in a vehicle, the hub comprising:
a reception processing device configured to receive a voice signal from at least one transmission terminal among two or more wearable terminals in the vehicle;
a transmission processing device configured to transmit the voice signal to at least one reception terminal among the wearable terminals; and
a controller configured to establish a communication channel with each of the wearable terminals, select a target terminal based on a voice signal obtained from a conversation attempt terminal attempting to transmit voice, and control the reception processing device and the transmission processing device to relay voice information transfer between the conversation attempt terminal and the target terminal,
wherein the controller is configured to match one-to-one between wearable terminals and a seat number that distinguishes a seat of the vehicle, and select the target terminal by extracting the seat number from the voice signal.
