Principal differential analysis for detection of bilabial closure gestures from articulatory data

In this paper, a new statistical method for detecting bilabial closure gestures is proposed based on articulatory data. This segment-based bilabial closure detection scheme uses principal differential analysis (PDA) to extract articulatory gestures. The dynamic patterns of the tract variables (TVs) lip aperture, lip protrusion, and their derivatives, are… CONTINUE READING
