Method for controlling ambient sound and electronic device therefor

A method for controlling a dialog mode of a wireless audio device, the method comprising:

• detecting an utterance of a user of the wireless audio device based on an acceleration of the wireless audio device;
• entering into a dialog mode for outputting at least some of ambient sounds, in response to detecting the utterance of the user;
• and
• ending the dialog mode if no voice is detected for a specified time or longer in the dialog mode.

A wireless audio device comprising:

• at least one internal microphone facing a user when the wireless audio device is worn;
• at least one external microphone exposed to an outside when the wireless audio device is worn;
• an audio output circuit;
• an acceleration sensor;
• a communication circuit;
• a processor;
• and
• a memory,
• wherein the memory stores instructions that, when executed by the processor, cause the wireless audio device to:
• detect an utterance of a user of the wireless audio device by using the at least one internal microphone and the acceleration sensor,
• determine whether the utterance of the user corresponds to an utterance for calling a voice agent,
• enter into a dialog mode in which at least some of ambient sounds received by the at least one external microphone are output through the audio output circuit, if the utterance of the user does not correspond to the utterance for calling the voice agent, and
• end the dialog mode if no voice is detected for a specified time or longer through the at least one external microphone in the dialog mode.
