An artificial intelligence robot for providing a voice recognition service includes a memory configured to store voice identification information, a microphone configured to receive a voice command; and a processor configured to extract voice identification information from a wake-up command included in the voice command and used to activate the voice recognition service and operate the voice recognition function in a deactivation state when the extracted voice identification information does not match the voice identification information stored in the memory.

Artificial intelligence robot for providing voice recognition function and method of operating the same

A voice recognition method of an artificial intelligence robot device is disclosed. The voice recognition method includes collecting a first voice spoken by a user and determining whether a wake-up word of the artificial intelligence robot device is recognized based on the collected first voice; if the wake-up word is not recognized, sensing a location of the user using at least one sensor and determining whether the sensed location of the user is included in a set voice collection range; if the location of the user is included in the voice collection range, learning the first voice and determining a noise state of the first voice based on the learned first voice; collecting a second voice in an opposite direction of the location of the user according to a result of the determined noise state of the first voice; and extracting a feature value of a noise based on the second voice and removing the extracted feature value of the noise from the first voice to obtain the wake-up word. The artificial intelligence robot device may be associated with an artificial intelligence module, an unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, devices related to 5G services, and the like.

Voice recognition method of artificial intelligence robot device

A robot for providing a guidance service using artificial intelligence. The robot measures distances between external robots and the robot and, based on the measured distances, determines that robots are concentrated in a specific area. Based on the determination that robots are concentrated in the specific area, the robot moves some of the external robots to the specific area.

Robot for providing guidance service using artificial intelligence and method of operating the same

Disclosed herein is an artificial intelligence device including a communication interface configured to receive a reference signal in a time domain for echo cancellation of an external device and a processor configured to determine whether a spectral density at at least one test target frequency is less than or equal to a preset spectral density reference value at at least one test target time point and determine that a failure occurs in an audio component when the spectral density is less than or equal to the preset spectral density reference value.

Artificial intelligence device for diagnosing failure and 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 disclosure relates to a mobile terminal capable of displaying image data and a control method thereof. A mobile terminal according to an embodiment of the present disclosure may include a camera configured to acquire an image to generate image data containing at least one face image; a microphone configured to receive audio data; and a controller configured to analyze a face image contained in the image data to determine contact information matched to the face image, and analyze the audio data to determine contact information matched to the audio data, and match the audio data to the image data based on the determined contact information.
