Báo cáo khoa học: "Making Sense of Sound: Unsupervised Topic Segmentation over Acoustic Input" docx

... Technology {igorm,malex,regina,glass}@csail.mit.edu Abstract We address the task of unsupervised topic segmentation of speech data operating over raw acoustic information. In contrast to ex- isting algorithms for topic segmentation of speech, our approach ... of Acoustic Comparison Matrix The goal of this step is to construct an acoustic com- parison matrix that wi...
