ESRD03 Database and the Labeling for Environmental Sound Recognition

ESRD03 is the database collected from 21 sound effect CDs and RWCP (Sound Scene Database in Real Acoustic Environment) database for environmental sound recognition, including more than 16000 sound tracks and most of them happening in home environments. This paper introduces the database manipulation of segmenting and labeling the data manually. Firstly the tracks are categorized according to their differences on the object, material and motion of the sources. Then the tracks are segmented and labeled in each category. Except for the high level labeling on the basis of content description, which gives the natural description of the sound and is close to the human sense, the properties of event is also segmented and labeled if it can be sensed. Also several labeling schemes are designed in each category for the labeling of the different characteristics of the sound. And the sound can be labeled with different labeling schemes simultaneously. The scheme is designed for the reference of the automatic property extraction and evaluation, and the identification study. It is on the basis of the preliminary research on the environmental sound recognition and the results show the sense of the scheme.
