Abstract

The invention relates to the technical field of sound recognition, and provides a low-resource sound event detection method and device, equipment and a storage medium, and the method comprises the steps: obtaining a to-be-detected sound; inputting sound to be detected into the trained sound group category neural network model to obtain sound group category information; inputting the sound to be detected into an encoder of a pre-trained sound event category judgment model to obtain fine-grained feature information, and splicing and fusing the group category information and the fine-grained feature information to obtain fused feature information; and inputting the fused feature information into a decoder of a sound event category judgment model, and decoding the fused feature information by combining a pre-obtained group category representation matrix based on an attention mechanism to obtain a sound event judgment result. According to the invention, the to-be-detected sound forms the large-class group sound group class information containing rich information, and auxiliary discrimination based on large-class sound event results is realized through a self-attention mechanism.

Description

technical field [0001] The present application relates to the technical field of sound recognition, and in particular, to a sound event detection method, apparatus, device and storage medium. Background technique [0002] Sound event detection (Sound Event Detection) aims to distinguish various sound signals from a continuous sound signal stream and mark the sound events symbolically. Different from tasks related to speech processing, such as speech recognition, voiceprint recognition, and emotion recognition, which only focus on the content of human speech signals, sound event detection focuses on a wider range, from nature, mechanical equipment, animals and plants, and the things we encounter in our daily life. All kinds of sounds are the research field of sound event detection. [0003] As the basic task of identifying sound signals, sound event detection has been applied in various aspects, such as urban traffic and security monitoring, factory noise and equipment abnor...
