Abstract	This research attempts to clarify the human vocal mechanism from engineering viewpoints by simulating the vocal movement with a robot, and to create a dynamic model. The authors developed an anthropomorphic talking robot, WT-1 (Waseda Talker-No.1) in 1999. It simulated the human vocal movement,. and had articulators and vocal organs. WT-1 could speak Japanese vowels (\|a\|, \|i\|, \|u\|, \|e\|, \|o\|). However, the vowels produced were not natural. Therefore, we develop a refined talking robot WT-1R that improves the realization of natural vowels and consonant sounds. WT-IR has articulators (the 6-DOF tongue, 4-DOF lips, 1-DOF teeth, a nasal cavity and a 1-DOF soft palate) and vocal organs (the 1-DOF lungs, 2-DOF vocal cords). The total DOF of the robot is 15. This paper describes the improved mechanisms of WT-IR and the realization of the fluctuation for the natural voice and the clearness of vowels.
