| Abstract(in English) | Coarticulation reduces word spotting accuracy in continuous speech when isolated uttered words are used as reference patterns for continuous DTW. In this paper, a contextual effect model was used as a front-end processor for word spotting to cope with coarticulation effects. The model adopted perceptual shifts by adjacent spectral peaks and has the ability to recover neutralized phonemes in continuous speech and can reduce vowel recognition error rates. The experiment results show that the model can improve word spotting accuracy. |
