Problems solved by technology

[0005] However, the existing audio event monitoring schemes generally adopt an end-to-end supervised training method, which has certain requirements for labeling. It needs to be trained with label information accurate to the audio frame level to give the event information of the label. It is impossible to pass training without audio frame-level annotation information and give tag event information

Abstract

The invention discloses an audio event monitoring method and device based on weak label labeling and computer equipment. The method comprises the following steps: acquiring an audio event, carrying out weak label labeling without an audio frame level on the audio event, extracting audio features of the audio event labeled by the weak label without the audio frame level, and training the extractedaudio features by adopting a cross entropy model mode, and matching event information of the label of the audio event labeled by the weak label according to the trained audio features. Through the above mode, the event information of the label can be given through training under the condition of no audio frame level labeling information.

Description

technical field [0001] The present invention relates to the technical field of audio event monitoring, in particular to an audio event monitoring method, device, and computer equipment based on weak label annotation. Background technique [0002] Audio event monitoring technology has always been a core problem in the audio field. Since the audio itself can contain a lot of event acoustic information, the audio information can be used for event recognition in many application scenarios. [0003] With the improvement of China's network infrastructure and the improvement of people's living standards, data in fields such as live broadcast and video have shown explosive growth. Because most of this kind of data is of a broadcast nature and has a certain social influence, it is often used by criminals to seek benefits, including but not limited to: disseminating obscene and pornographic information, disseminating violations of law and discipline, speech, etc. [0004] In 2017, G...
