Abstract: An electronic device includes a communication module and a processor operatively connected to the communication module. The processor is configured to: receive and store a first speech voice related to at least a first external device, and a second speech voice related to a second external device; if individual speech is detected, transmit the first speech voice or the second speech voice having a first playback speed to at least a first external device and a second external device; and, if simultaneous speech is detected, convert, into a second playback speed different from the first playback speed, at least a part of a synthesized voice in which at least first overlap speech of the first speech voice and at least second overlap speech of the second speech voice are successively connected, and transmit the synthesized voice to the at least first external device and the second external device.

Abstract: An electronic device is provided. The electronic device includes a plurality of microphones disposed at different positions in the electronic device, a processor configured to collect input signals input to each of the microphones, acquire direction of arrival (DOA) information corresponding to each of the microphones from the input signals, calculate generation directions of the input signals using the DOA information, adjust a weight of an input signal for each of the microphones, based on the generation directions of the input signals, and generate an output signal for each of the microphones by reflecting the weight adjusted for each of the microphones, and a speaker configured to output an output signal for each of the microphones.
