Multimodal structure segmentation and analysis of music using audio and textual information
In this paper, we present a multimodal approach to structure segmentation of music with applications to audio content analysis and music information retrieval. In particular, since lyrics contain rich information about the semantic structure of a song, our approach incorporates lyrics to overcome the existing difficulties associated with large acoustic variation in music. We further design a constrained clustering algorithm for music segmentation and evaluate its performance on commercial recordings. Experimental results show that our method can effectively detect the boundaries and the types of semantic structure of music segments.
