N2 - In this study, a speaker-adaptive articulatory model was constructed by fitting point-wise articulatory positions measured by electromagnetic articulography (EMA) to the vocal tract framework in [5] to customize a standard vocal tract model with speaker-dependent articulatory features. With the speakeradaptive articulatory model, the area functions of oral and nasal vowel pairs (/a/, /i/, /u/) were simulated. The differences of area functions between oral and nasal vowels were decomposed into orthogonal modes [10] to account for the primary oropharyngeal articulatory changes related to nasalization. The relationship between the principal articulatory modes and the lowest two formant frequencies (F1, F2) was examined to uncover the effect of oropharyngeal articulation on the acoustics of nasal vowels.
