Music style recognition method, apparatus, computer device and storage medium

Abstract

The invention discloses a music style recognition method, a music style recognition device, a computer device and a storage medium. The method includes the following steps that: an audio sample data set is acquired; the timbre features and rhythm features of audio samples are acquired; an initial hidden Markov model is trained according to the timbre features and the rhythm features, so that a timbre recognition model and a rhythm recognition model are obtained; to-be-recognized target audio data are received, and target timbre features and target rhythm features are obtained; the target timbre features are recognized according to the timbre recognition model, probabilities that the target timbre features belong to each musical style are determined, and N timbre probabilities are obtained;and the target rhythm features are recognized according to the rhythm recognition model, and probabilities that the target rhythm features belong to each musical style are determined, and N rhythm probabilities are obtained; and the target musical style of the target audio data is determined according to the N timbre probabilities and the N rhythm probabilities. With the music style recognition method, the music style recognition device, the computer device and the storage medium provided by the technical schemes of the present invention adopted, the accuracy of music style recognition can beimproved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a music style recognition method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of Internet technology, online music not only has various forms, but also has been growing explosively. In the face of massive online music, how to quickly search for favorite music has become a research hotspot. [0003] Music style types are often used in the management of digital music databases, so the identification and classification of music styles play an important role in Music Information Retrieval (MIR). Narrow the search scope and improve the search speed. [0004] However, the current traditional music style recognition and classification methods do not fully extract the features of the original audio data, and the accuracy of music style recognition and classification is not high, which affects the accuracy of music information ret...
