Abstract
Provided are an intelligent voice recognition method, a voice recognition device, and an intelligent computing device. A method of intelligently recognizing a voice in a voice recognition device includes obtaining an ambient noise signal from the microphone detection signal when a voice is detected from the microphone detection signal; updating a previously learned noise cancellation model based on the ambient noise; and removing the ambient noise signal from the microphone detection signal. Therefore, a voice recognition performance of the voice recognition device can be maximized. At least one of the voice recognition device, the intelligent computing device and the server of the present disclosure may be associated with an Artificial Intelligence module, a drone (Unmanned Aerial Vehicle, UAV), robot, Augmented Reality (AR) device, virtual reality (VR) device and a device related to the 5G service.
