1. An electronic apparatus comprising:
an interface configured to receive a first audio signal from a first microphone set and receive a second audio signal from a second microphone set provided at a position different from that of the first microphone set;
a processor configured to:
obtain a plurality of first sound-source components based on the first audio signal and a plurality of second sound-source components based on the second audio signal, the plurality of first sound-source components comprising a plurality of first audio signal frequency components and the plurality of second sound-source components comprising a plurality of second audio signal frequency components;
identify a first sound-source component, from among the plurality of first sound-source components and identify a second sound-source component from among the plurality of second sound-source components, by comparing each of the plurality of first sound-source components with each of the plurality of second sound-source components, wherein the identified first sound-source component and the identified second sound-source component correspond to each other;
identify a user command based on the first sound-source component and the second sound-source component; and
control an operation corresponding to the user command.
