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 method comprises the steps: carrying out the marking of sample audio data according to a preset music style label, and generating a marked audio sample; cutting the labeled audio sample into a plurality of labeled audio data segmentswith 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 preset music style labels of the annotation sample audio segment feature vectors in the annotation sample set to obtain an annotation sample audio training set; and training the annotated sample audio training set by using a deep learning method to obtain a first music style annotation model. The purpose of inputting the target audio data into thefirst music style labeling model to obtain the music style label is achieved.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a model generating method, an audio processing method, 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 to facilitate users to search for interesting videos or audios on video or audio websites, greatly enriching users' lives. [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 function of recommending audio and video to users according to the music style of the audio and video data has a great demand. However, in the prior art, music style labeling of audio and video websites is often done manually, which is inefficient and expensive. [0004] Therefore, how to efficiently and accurately mark the music style of the aud...
