Abstract: An automatic translation device includes a communications module transmitting and receiving data to and from an ear-set device including a speaker, a first microphone, and a second microphone, a memory storing a program generating a result of translation using a dual-channel audio signal, and a processor executing the program stored in the memory. When the program is executed, the processor compares a first audio signal including a voice signal of a user, received using the first microphone, with a second audio signal including a noise signal and the voice signal of the user, received using the second microphone, and entirely or selectively extracting the voice signal of the user from the first and second audio signals, based on a result of the comparison, to perform automatic translation.
