First International Conference on Spoken Language Processing (ICSLP 90)
Toward a goal of developing a speech training system, three methods of processing the high-speed palatographic data are proposed for better graphical expression of articulatry behaviors of the tongue. The first is the lateral shape for tongue-palate contact point, the second is the lateral loci for the tounge movement, and the third is the cumulative map for tongue-palate contact during a specified period of the utterance. A scrutiny of the results, obtained by these methods for the dental or dentalveolar stops and fricatives, elucidates the subtle differences of articulatry behaviors among these consonants.
