Features extraction and temporal segmentation of acoustic signals.

Abstract

This paper deals with temporal segmentation of acoustic signals and features extraction. Segmentation and features extraction are aimed at being a first step for sound signal representation, coding, transformation, indexation and multimedia. Three interdependent schemes of segmentation are defined, which correspond to different levels of signal attributes. A complete segmentation and features extraction system is shown. Applications and results on various examples are presented. The paper is divided into four sections: a definition of the segmentation schemes; and description of the techniques used for each of them.
