Abstract：Analyses of the vocal tract resonant characteristics need accurate models of the vocal tract shape. This article presents a three-dimensional Mandarin vocal tract model using vocal tract shape data and midsagittal radius vector data from MRI images for seven Mandarin sustained vowels[a],[o],[r],[i],[u],[y] and[e]. The vocal tracts images were cut into 36 sections of equal distances along the midline of the vocal tract. The Mandarin vocal tract model for each section is then driven by the length of the radius vector in the cross-sectional images. The sound synthesized by this model sounds very much like natural speech.
