Robustness of a feature based phoneme segmentation system to speaker independent and continuous speech

The authors present the outline and performance of a feature based phoneme segmentation expert system, tested on speaker independent and continuous speech. This system utilizes spectrogram reading knowledge and the strategy used by a human expert when reading a spectrogram, and determines the phoneme boundary along with its phoneme class. The experiments were performed both on isolated word speech uttered by six male speakers and on speaker dependent continuous speech. The results were as good as, or slightly worse than those of the previous experiment on speaker-dependent isolated word speech. The authors report on the difference in the knowledge between speakers and utterances, which was added and/or modified for this expansion to speaker independent and continuous speech
