Abstract

This paper describes methods for automatic extraction of descriptive metadata for audio material and the workflow
of archiving. These new algorithms and archiving tools developed at Fraunhofer IMK are to be directly integrated
into MediaFabric, a commercially available radio broadcasting framework. Processing steps are based on pattern
recognition algorithms and include speech/non-speech detection, speaker change detection and classification, jingle
and advertising recognition. The extracted audio structure is described as a hierarchical representation of segment
nodes annotated with suitable metadata. An extended retrieval application allows interactive display and navigation
of the audio structure. A novel approach to keyword search based on a syllable representation of audio material is
used for effective retrieval within the digital radio archive.
