Šmídl, L. and Müller, L. and Psutka, J. : Improving a keyword spotting system using phoneme sequence . WSEAS TRANSACTIONS on COMPUTER, p. 751-755, WSEAS, Greece, 2003.


This paper presents a technique for improving keyword spotting. The main idea is based on the combination of a standard keyword spotting system working with a filler model with a phone recognizer. If the filler model is well designed it produces a phoneme sequence corresponding to the investigated utterance. This phoneme sequence generated by a filler model can be used to reject incorrectly detected keywords. The quality of this technique depends on how good is the acoustic match between an incoming utterance and a bigram phoneme filler model.
