Abstract
An electronic device and method are disclosed. The electronic device includes a first microphone, a second microphone, a memory; and a processor. The processor implements the method, including: determining whether a voice is detected in a first sound signal detected by the first microphone; determine whether a present recording period is a voice period or a silent period based on the determination, when the present period is the silent period, receive a second sound signal via the second microphone and analyze a noise signal included therein, remove noise signals from one of the first and second sound signals, based on characteristics of the voice period or the analyzed noise signal, and combine the first and second sound signal into an output signal and transmit the output signal to an external device.
