This paper describes vocal tract configuration for continuous vowels by using a data glove. The authors have proposed data-glove-driven vocal tract configuration methods and showed the usefulness of a method with three fingers for producing vowel sounds. In the method, the location of constriction, the degree of constriction, and the lip area are controlled by bending the thumb, middle finger, and index finger, respectively. Moreover, the effectiveness of training for continuous vowels was shown for sequence /aiueo/. Whether any combination of vowels can be synthesized by this method is an interesting topic for confirmation of the effectiveness. To examine the possibility of successful manipulation of the data glove, an experiment for synthesizing various three consecutive vowels was performed with five beginner subjects. Japanese vowel sequences of 60 patterns were used in the experiment. The results proved that the subjects were able to successfully produce the vowel sequences immediately after showing a target sequence through three training sessions for manipulating the data glove.
