VOICE RECOGNITION DEVICE AND METHOD

The present disclosure relates to an electronic device for recognizing a user voice and a method for recognizing a user voice by the electronic device. According to an embodiment, a method for recognizing a user voice may comprise the steps of: acquiring an audio signal divided into a plurality of frame units; by applying a filter bank distributed according to a preconfigured scale to a frequency spectrum of the audio signal divided in units of the frames, determining an energy component for each filter bank; smoothing the determined energy component for each filter bank; extracting a feature vector of the audio signal on the basis of the smoothed energy component for each filter bank; and recognizing the user voice in the audio signal by inputting the extracted feature vector into a voice recognition model.
