Keyword spotting method based on speech feature space trace matching
WU Ya, Baolong Liu · 2004
Keyword spotting (KWS) has been an active research area in recent years. Based on the theory of feature space trace time normalization, an efficient keyword spotting method is proposed in this paper, with the effect of the fragment trace length probed. Experiments show that the performance of this method is close to that of manual spotting, having some practicability.
