Abstract(in English) In this paper, a method of the dynamic vocal tract shape estimation for VCV sound waveform using a method of analysis-by-synthesis in articulat cry-acoustic transformation is proposed. The 11-dimensional model which expressed vocal tract area function with 11 parameters is used for a vocal tract shape model. Moreover, it assumes that a sequence VCV is known, an initial value is set the typical value from MRI data, and the sigmoid function expressed phase and speed information in VCV transion. Furthermore, dynamic vocal tract shape is estimated by the A-b-S method in order of F2 and F1, and the highly sensitive articulation feature. As a result of applying this method about the VCV sound of [iia], [ija], [ira], [iwa], [li] and [ri] uttered by men, dynamic vocal tract shape can be estimated directly, the phase and speed information for discrimination of similar words were obtained, and the validity of this method was checked.
