1. A method for a control device to receive a voice signal from at least one device in a short-range wireless communication system, the method comprising:
receiving a first advertisement message for measuring a declination angle between devices from the at least one device, respectively;
measuring each declination angle between a reference point set in the control device and positions of the at least one device based on the first advertisement message, wherein the positions of the at least one device are respectively adjusted such that each declination angle satisfies a specific angle for receiving a voice signal, based on the measured respective declination angles;
receiving each of a first voice signals based on the respective adjusted positions from the at least one device; and
measuring a volume of the received first voice signal, respectively,
wherein based on the measured volume, an audio signal output angle of the at least one device is adjusted such that an audio signal received by the control device is incident at right angles to the control device, respectively.
