Abstract

The invention discloses a sound event detection method and device, a storage medium and an electronic device. The sound event detection method comprises the following steps: acquiring target feature segmentation of a target audio so as to obtain N sub-target features; respectively inputting the sub-target features with the same score in the N sub-target features into corresponding M target sound detection models to obtain M positive example score sequences, performing enhancement processing on first sample features of multiple sample audios based on a spectrogram and a time domain in a training process of each target sound detection model to obtain second sample features, and training M sound detection models through the first sample features and the second sample features, wherein M is a positive integer greater than or equal to 1; averaging and fusing the M positive example score sequences; and determining the detection result of the target audio according to a target fusion positive example score sequence. Thus, the technical problem of low accuracy of a sound event detection result in the prior art is overcome.

Description

technical field [0001] The present invention relates to the fields related to artificial intelligence technology and sound event detection, in particular to a sound event detection method, device, storage medium and electronic device. Background technique [0002] Whether in personal home life or work, artificial intelligence (AI)-based systems are gradually becoming an integral and important part of daily activities. The most common method of deep learning is supervised learning. The purpose of the application is to collect a large number of data samples and labels to form a data set. This dataset is divided into three parts: training, validation and testing. In the training phase, the data from the training and validation sets and their respective labels are input to the model, and the parameters are updated based on backpropagation to optimize the model. In the testing phase, the test data is fed into the model with fixed parameters, and the class of the test data sampl...
