Abstract

This report describes research on topic spotting in audio document retrieval carried out in years 2 and 3 of the Cambridge Video Mail Retrieval (VMR) project. Topic spotting within VMR was concerned with ad-hoc querying of a message archive using classical information retrieval techniques developed from experience with text archives. The report describes experiments using three approaches to document indexing: fixed-vocabulary keyword spotting, open-vocabulary search term indexing using phone lattices, and message transcription using large vocabulary speech recognition. Additional experiments investigate the combination of these techniques for improved retrieval effectiveness.
