Voice output of a specific speaker is controlled using beamforming according to a video zooming magnification. By simultaneously performing adaptive beamforming and fixed beamforming, it is possible to reinforce voice output of the specific speaker.

Artificial intelligence device configured to generate a mask value

A far-end terminal including a communication interface configured to wirelessly communicate with a near-end terminal for performing a video conference between the far-end terminal and the near-terminal, a camera configured to capture a region in front of the far-end terminal including a plurality of counterpart speakers, a display configured to display the plurality of counterpart speakers captured through the camera and to display an image of a speaker at the near-end terminal, and a processor configured to receive focusing mode setting information from the near-end terminal indicating an operation mode of the near-end terminal is a wide focusing mode, in response to the focusing mode setting information indicating the operation mode is the wide focusing mode, obtain an angle range corresponding to a narrower partial region of an entire region including the plurality of counterpart speakers at the far-end terminal, perform selective audio focusing on a received voice within the obtained angle range to selectively increase a gain of the received voice and to selectively decrease a gain of other received voices outside the obtained angle range, and transmit audio, which is a result of performing the beamforming, to the near-end terminal.

Far-end terminal and voice focusing method thereof

A mobile terminal includes: a microphone; a short-range communication module; and a controller operably coupled to the microphone and the short-range communication module. The controller is configured to: establish communication with a wearable device via the short-range communication module; enter an audio recognition mode when the communication is established with the wearable device to perform surrounding context awareness in response to audio received via the microphone; and cause the short-range communication module to transmit notification information corresponding to a preset audio signal to the wearable device when the preset audio signal is detected in the audio.

Mobile terminal

The present specification discloses various embodiments of a digital device and a method for controlling the same. A method for controlling a digital device according to an embodiment of the present invention may comprise the steps of: connecting to a repeater; sensing an external device located within a preconfigured distance and connected to the repeater; receiving an audio reference data transmission request from the sensed external device; and transmitting the requested audio reference data to the external device.
