Abstract

The embodiment of the invention provides a model generation method, an audio processing method and device, a terminal and a computer readable storage medium, and the model generation method comprisesthe steps: annotating music emotion of sample audio data to obtain an annotated audio sample; cutting the labeled audio sample into a plurality of labeled audio data segments with preset lengths; processing each labeled audio data segment into a plurality of labeled sample audio segment feature vectors with preset dimensions, and taking the labeled sample audio segment feature vectors as labeled sample sets; updating the music emotion tags of the annotated sample audio segment feature vectors in the annotated sample set to obtain an annotated sample audio training set; and training the annotated sample audio training set by using a deep learning method to obtain a first music emotion annotation model. The purpose of inputting the target audio data into the first music emotion labeling model to obtain the music emotion label is achieved.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a model generating method, an audio processing method, a device, a terminal and a computer-readable storage medium. Background technique [0002] With the popularity and development of video or audio networks, many video and audio websites have sprung up, which are convenient for users to search for interesting videos or audio on video or audio websites, which greatly enriches users' lives. Among them, music is a reflection of human beings. The art of real life emotion, short video is a popular way of expression. [0003] At present, a large amount of user-made or officially produced audio and video data stored on video or audio websites is available for users to use. Among them, the content of audio and video often matches the emotion of music to express emotions. With the popularity of audio and video, the number of audio and video is increasing day by day, and there ...
