Abstract
Disclosed herein are a method for extracting voice signals of a plurality of users, and a terminal device and a robot implementing the same. The robot includes a plurality of microphones respectively corresponding to a plurality of users, a memory and a processor, where the processor extracts a plurality of voice signals output by each of the plurality of users using a plurality of sound signals received by each of the plurality of microphones, and in this case, the processor reverses a phase of at least one of other sound signals received respectively by at least one of other microphones except an i-th microphone, and extracts an i-th voice signal output by an i-th user corresponding to the i-th microphone based on a i-th sound signal received by the i-th microphone and based on at least one of other sound signals, the phase of which is reversed.
