Apparatus and method for generating audio signal with noise attenuated based on phase change rate
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.
