US Patent 11417323 Electronic apparatus and control method thereof

An electronic device is provided. The electronic apparatus includes a communication interface, and at least one processor configured to receive a first audio signal and a second audio signal from a first sensor device, and a second sensor device located away from the first sensor device, respectively, through the communication interface, acquire similarity between the first audio signal and the second audio signal, acquire a first predicted audio component from the first audio signal based on an operation state of an electronic apparatus located adjacent to the first sensor device, and a second predicted audio component from the second audio signal based on an operation state of an electronic apparatus located adjacent to the second sensor device in the case where the similarity is equal to or higher than a threshold value, identify one of the first sensor device or the second sensor device as an effective sensor device based on the first predicted audio component and the second predicted audio component, and perform speech recognition with respect to an additional audio signal received from the effective sensor device.
