Abstract: Disclosed is a voice recognition device and method. According to the disclosure, the voice recognition device, upon failing to grasp the intent of the user's utterance from the original utterance which is divided into a head utterance and a tail utterance, figures out the intent from the head utterance to thereby complete the original utterance and provides the result of voice recognition processing on the original utterance. According to an embodiment, the voice recognition device may be related to artificial intelligence (AI) modules, robots, augmented reality (AR) devices, virtual reality (VR) devices, and 5G service-related devices.

Abstract: A voice processing method is disclosed. The voice processing method applies first and second sentence vectors extracted from first and second utterances, that are included in one dialog group and are separated from each other, to a learning model and generates an output from which at least one word having an overlapping meaning is removed. The voice processing method can 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.
