Abstract: An electronic device is provided. The electronic device includes, for the purpose of determining a customized beamformer filter, an input module including a plurality of microphones configured to receive an external sound signal, a memory configured to store computer-executable instructions and an initial value of a voice parameter used to perform beamforming on the external sound signal, and a processor configured to execute the instructions by accessing the memory. The instructions may be configured to estimate a feature value of the external sound signal, calculate the initial value of the voice parameter used to perform beamforming based on the external sound signal received by the plurality of microphones, determine whether to store the calculated initial value according to the feature value, determine which one of the calculated initial value or an initial value stored in the memory used according to the feature value, and obtain a target voice parameter.

Abstract: The present disclosure relates to an electronic device and an operating method thereof, the electronic device comprising: a speaker; an external microphone configured to obtain an external signal for the electronic device; an internal microphone positioned within a specified distance of the speaker and configured to obtain an internal signal including a signal output from the speaker and/or a signal obtained from the signal output from the speaker and reflected by an external object; a memory storing a first transfer function generated on the basis of the signal output from the speaker and obtained by the internal microphone, and/or a second transfer function generated on the basis of the signal obtained from the signal output from the speaker and reflected by the external object, the signal being obtained by the internal microphone; and a processor operatively connected to the speaker, the external microphone, and the internal microphone, wherein the processor may be configured to: convert a signal obtained by the external microphone into an external frequency signal in the frequency domain; convert a signal obtained by the internal microphone into an internal frequency signal in the frequency domain; calculate a first compensation value on the basis of comparing the external frequency signal with the internal frequency signal; and control an output signal output from the speaker, on the basis of the external signal obtained by the external microphone, the first compensation value, and the first transfer function and/or the second transfer function.
