Abstrakt

This paper describes several approaches to  keyword spotting(KWS)  for informal continuous speech. We compare  acoustickeyword spotting, spotting in word lattices generated by largevocabulary continuous speech recognition and a hybrid approach makinguse of phoneme lattices generated by a phoneme recognizer. The systems are compared on carefully defined test data extracted from ICSImeeting database. The  acoustic and phoneme-lattice based KWS arebased on a phoneme recognizer making use of temporal-pattern (TRAP)feature extraction and posterior estimation using neural nets. We showits superiority over traditional HMM/GMM systems. The advantages anddrawbacks of different approaches are discussed.
