1. An electronic device comprising:
one or more microphone arrays including a plurality of microphones;
at least one processor operatively connected to the one or more microphone arrays; and
at least one memory electrically connected to the at least one processor,
wherein the at least one processor comprises a first processor and a second processor which is capable of operating logically or physically separately from the first processor,
wherein the memory stores instructions which, when executed, enable the first processor to:
receive a wake-up utterance, which calls a designated voice service, using first group microphones among the plurality of microphones, while operating in a first state,
request a verification of the received wake-up utterance to the second processor, wherein the second processor operates in a second state in response to receiving the request of the verification of the wake-up utterance,
receive a first subsequent utterance using the first group microphones among the plurality of microphones while the verification of the wake-up utterance is performed by the second processor, and
in case that the second processor completes the verification of the wake-up utterance, provide the first subsequent utterance to the second processor,
wherein the second processor is configured to receive a second subsequent utterance using second group microphones among the plurality of microphones, while operating in the second state, and
wherein the second group microphones comprise microphones, a number of which is greater than a number of the first group microphones.
