Abstract: An electronic device is provided. The electronic device includes a speaker, a microphone, a processor, and a memory. For example, the electronic device may obtain a first audio signal during a first specified time by using the microphone, may identify reference noise intensity based on the first audio signal, may obtain a second audio signal exceeding the reference noise intensity by using the microphone, may turn off the microphone based on a fact that a third audio signal having the reference noise intensity or less is obtained during a second specified time or longer, and may modulate and output the second audio signal through the speaker while the microphone is turned off.

Abstract: An electronic device according to various embodiments comprises a communication module including communication circuitry, at least one microphone, and a processor. The processor can be configured to: be connected to an external device through the communication module; switch a call audio signal path to an external device output path in response to being call-connected to an opponent device; duplicate a call audio signal (Rx in) transmitted from the opponent device, provide a first signal to an echo removal module, and provide a second signal to the external device via the external device output path; measure latency between the external device and the electronic device; variably adjust the size of a dynamic buffer for removing echo, by applying the measured latency; generate a reference signal delayed in the second signal, by the adjusted dynamic buffer; and remove an echo signal, with respect to the first signal generated from a speaker of the external device, from a microphone input signal obtained from the at least one microphone, based on the generated reference signal.
