Abstract
According to various embodiments, an electronic device includes a plurality of microphones, and a processor electrically connected to the plurality of microphones, wherein the processor may obtain audio signals through the plurality of microphones, estimate a probability of existence of a voice signal included in the obtained audio signals, obtain correlation information between the audio signals based on the probability of existence of the voice signal and/or the obtained audio signals, obtain voice blocking information based on the correlation information or a direction of arrival (DOA) estimation, obtain a first signal among the audio signals based on the audio signals, the correlation information, and the voice blocking information, obtain a second signal including the voice signal among the audio signals, and obtain a noise-removed voice signal by removing the first signal from the second signal. In addition, it is possible to implement various embodiments understood through the disclosure.
