Abstract

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.
