A fast lattice-based approach to vocabulary independent wordspotting

Abstract

Practical applications of wordspotting, such as spoken message retrieval and browsing, require the ability to process large amounts of speech data at speeds many times faster than real-time. This paper presents a novel approach to this problem in which all of the stored audio material is prepro-cessed oo-line to generate a phoneme lattice. At search time… (More)
