Phoneme recognition in contiunous speech using phoneme discriminant filters

We describe in this paper a new phoneme recognition system using phoneme discriminant filters for speaker independent continuous speech. The segmentation of speech and the classification of phoneme are carried out simultaneously by the phoneme discriminant filters. Each of them detects the candidate of the specified phoneme in input speech independent of the other phonemes. The final recognition result is uniquely determined from the outputs of the filters through the unification process. The recognition scores are 88.1% for the training set and 76.0% for the test set uttered by the other 5 male speakers.
