An electronic apparatus is provided. The electronic apparatus includes a communication interface and a processor configured to, based on receiving a first audio signal from a first sensor device from among a plurality of sensor devices through the communication interface, perform an operation corresponding to the first audio signal, and control the first sensor device to output a second audio signal indicating a result of performing the operation corresponding to the first audio signal, and based on receiving a third audio signal from a second sensor device from among the plurality of sensor devices within a threshold time from a time of controlling the first sensor device through the communication interface, determine whether to process the third audio signal based on the second audio signal and the third audio signal. In particular, at least part of a method of determining whether to process the third audio signal may use an artificial intelligence model that is trained according to at least one of a neural network or a deep learning algorithm.
