Audio Segmentation
Abstract
This chapter focuses on a vital stage of audio analysis, the audio segmentation stage, which focuses on splitting an uninterrupted audio signal into segments of homogeneous content. The chapter describes two general categories of audio segmentation: those that employ supervised knowledge and those that are unsupervised or semi-supervised. In this presentation context, certain specific segmentation tasks are presented, e.g., silence removal and speaker diarization.
