Abstract

The invention discloses an audio scene classification method, device and equipment applied to audio monitoring, and aims to solve problems that an existing audio scene classification mode consumes time and wastes resources from two aspects, on one hand, quality research and judgment are carried out on each audio segment in real time on the basis of processing timeliness, and on the other hand, theaudio scene classification efficiency is improved; according to the method, only the effective audio clips are detected, the audio clips are taken as processing units, and processing of other available clips is stopped once the classification result is detected, so unnecessary detection processes can be greatly reduced; on the other hand, by utilizing the characteristics of the RNN architecture,the information of each audio clip does not need to be stored in the scene type detection process, and only the processing result of the previous step needs to be used as the input of subsequent processing, so the resource space can be fully saved; therefore, the method not only can guarantee the processing time efficiency, but also can enable the system to be light in weight, thereby being flexibly suitable for audio monitoring application environments of various scales.

Description

Technical field [0001] The present invention relates to the field of audio monitoring, and more particularly to an audio scenario classification method, apparatus, and apparatus for use in audio monitoring. Background technique [0002] After years of development in the field of audio monitoring, the role of the high-quality smart security system has highlighted its importance. Since the technical characteristics of the audio itself will not be interfered by the line of sight obstacles, the illumination is unfavorable, can make up for the insufficient visual, and provide a variety of information for the determination situation, and the function of video cannot be replaced. The audio scene analysis is mainly for analysis, decision-making, and anomalous behavior that occurs in the current listener environment. Its core technology is based on various types of abnormal audio, and the classification method of time domain, frequency domain, combined with the classification method ident...
