Abstract:

To solve the problem of high cost and redundant pieces generation of content-based analysis, a lyrics-based analysis to detect the music structure was proposed, combing SVM and beat to detect the boundaries of vocal and nonvocal, to correct the result of lyrics-based analysis. The experiment on the same database proves that our musical structure analysis algorithm that combines the lyrics and content has improved the accuracy of Bridge and Outro by 9％ and 11％ respectively.

Key words: musical structure, lyrics analysis, content analysis, support vector machine, vocal and non-vocal detection
