Abstract
Disclosed are an electronic device performing an audio zoom based on speaker detection using lip reading and a method for controlling the electronic device. According to an embodiment, the electronic device detects a direction of a sound source while recording a video and determines a speaker's direction via facial recognition and mouth shape recognition in the sound source direction. Microphone beamforming may be performed based on the speaker's direction. Thus, the accuracy of audio zoom may be enhanced.
