Electronic device and method of recognizing audio scene

Abstract

An electronic device and method of recognizing an audio scene are provided. The method of recognizing an audio scene includes: separating, according to a predetermined criterion, an input audio signal into channels; recognizing, according to each of the separated channels, at least one audio scene from the input audio signal by using a plurality of neural networks trained to recognize an audio scene; and determining, based on a result of the recognizing of the at least one audio scene, at least one audio scene included in audio content by using a neural network trained to combine audio scene recognition results for respective channels, wherein the plurality of neural networks includes: a first neural network trained to recognize the audio scene based on a time-frequency shape of an audio signal, a second neural network trained to recognize the audio scene based on a shape of a spectral envelope of the audio signal, and a third neural network trained to recognize the audio scene based on a feature vector extracted from the audio signal.
