Abstract

The invention relates to an audio recognition method and device, computer equipment and a storage medium, and relates to the technical field of machine learning. The method comprises the steps of acquiring frequency characteristics of at least one speech frame in audio data; inputting the frequency characteristics of the speech frames into a classification model; conducting weighting transformation on the frequency characteristics of the speech frames according to the frequency characteristics of the context speech frame of each speech frame through each BLSTM in the classification model to obtain a prediction probability that the audio data is a sensitive audio; when the prediction probability is greater than a probability threshold value, determining the audio data as the sensitive audio. By inputting the frequency characteristics of the audio data into the classification model and determining the audio data as the sensitive audio when the output predication probability is greater than the probability threshold value, the efficiency of the audio recognition is improved, manual screening by customer service personnel is avoided, and the manpower resources are saved.

Description

technical field [0001] The present disclosure relates to the technical field of machine learning, and in particular to an audio recognition method, device, computer equipment and storage medium. Background technique [0002] In related technologies, users can upload audio (or video containing audio) to the server through APPs such as WeChat, Weibo, and short video APP (application, application client). As the number of users increases, the number of audio files uploaded to the server also increases. In these audios, it is easy to include some sensitive audios restricted by policies and regulations, which will have a negative impact on the network platform served by the server. For example, the sensitive audios can be pornographic audios such as panting sounds. [0003] At present, on the server side, customer service personnel are usually arranged to manually screen the audio uploaded by users to identify the above-mentioned sensitive audio, so that the sensitive audio will ...
