    摘要: An electronic device is disclosed. In addition, various embodiments recognized through the specification are possible. The electronic device includes a plurality of input devices for receiving a plurality of input signals, each of which includes a speech signal and a noise signal and a processor electrically connected with the input devices. The processor is configured to determine a signal to noise ratio (SNR) value for the plurality of input signals for each frequency band, determine a first parameter indicating a phase shift to frequency in the plurality of input signals in a first frequency band where the SNR value is greater than or equal to a specified threshold, determine a second parameter indicating a phase shift to frequency in the plurality of input signals in a second frequency band where the SNR value is less than the threshold, and perform beamforming for the plurality of input signals based on the first parameter and the second parameter.
