An automatic audio classification system for radio newscast

Abstract

Current web search engines generally do not enable searches into audio files. Informative metadata would allow searches into audio files, but producing such metadata is a tedious manual task. Tools for automatic production of metadata are therefore needed. This project describes the work done on the development of an automatic audio classification system which can be used for this metadata extraction. In order to design this system I used adapting it to our case of study, the matlab code of the MPEG-7 Experimental Model [15].
