| Outline of Final Research Achievements |
We have developed a set of tools which model the human vocal-tract and give an intuitive understanding of the mechanism of human speech production. Some of our models produce consonants, such as nasals, approximants, flaps, plosives and fricatives. Other models produce vowels, especially the English, Japanese, and Estonian inventories. Both the Japanese and Estonian vowel models are on exhibition in museums. One model which we continued to develop over several years is a bent model which produces several different consonants. Another model, very well received, is a static anatomical model producing the vowel /a/ which shows the human anatomy of the vocal mechanism, including the lungs and thoracic cavity. We also developed an additional set of bent models based on Chiba and Kajiyama's measurements, and we have a sliding vocal-tract model in widespread use around the world.
