Abstract：The tongue tip motion in Standard Chinese was modeled based on articulatory data from magnetic resonance imaging (MRI) images. An MRI articulatory database was developed for Standard Chinese, including 9 vowels and 75 consonant variants. Principle component analysis (PCA) of the tongue shape was then used to find articulatory factors. The results show that the tongue should be divided as the tongue tip and tongue body and modeled separately for more precise results. The tongue tip motion is modeled with two articulatory parameters for tongue tip protrude and tongue tip raise which represent the protruding/advancing and raising/retroflexing movements of the tongue tip.
