Abstract: An artificial intelligence (AI) apparatus including a memory and a processor configured to estimate a sound source localization based on at least one of image information, sound source information, and sensor information stored in the memory. The processor is configured to pre-process at least one of the image information, the sound source information, or the sensor information to generate test data, input the test data into a pre-trained AI model to estimate the sound source localization, calculate a sound source localization estimation evaluation score of the AI model for the test data, classify the test data into validation data based on the calculated sound source localization estimation evaluation score, change the AI model based on the classified validation data, and input the test data into the changed AI model to update the AI model.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An engine system includes a cylinder block and a cylinder head. A coolant control valve unit is engaged with the cylinder head to receive a coolant exhausted from the cylinder block and a coolant exhausted from the cylinder head. The coolant control valve unit controls a coolant to be supplied to a heater, a radiator, and an oil cooler and controls the coolant exhausted from the cylinder block. The coolant control valve unit receives the coolant from the cylinder head, supplies the coolant to the oil cooler, and controls the coolant distributed to the heater and the coolant exhausted from the cylinder block.
