Abstract: Disclosed is a method for separating a speech based on artificial intelligence in a vehicle. The method includes separating a speech signal using at least one sound beam-forming or source separation; and performing a speech recognition function by detecting a speaker (user) of the separated signal, and accordingly, other users in the vehicle in addition to a driver may use the speech recognition function. A device and method for separating speech based on artificial intelligence in vehicle of the present disclosure can be associated with artificial intelligence modules, drones (unmanned aerial vehicles (UAVs)), robots, augmented reality (AR) devices, virtual reality (VR) devices, devices related to 5G service, etc.

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.
