The authors developed an anthropomorphic talking robot WT-1 (Waseda Talker No. 1). It simulates human vocal movement by using artificial vocal organs (lungs, vocal cords) and articulators (lips, teeth, tongue, nasal cavity, soft palate). We experimented it on vowels. Although WT-1's voice wasn't equal to human, it could utter all Japanese vowels (/a/, /i/, /u/, /e/, /o/).
