| Research Abstract |
I have improved the detection rate of mouth shapes from Japanese utterance images, and proposed a recognition method of Japanese words. I aimed for more than 90% at the detection rate of mouth shapes, but it was finally with 82.7% by using the optical flow and the template matching. This shows that the detection rate was improved by 8.6% from the grant start. By the recognition of the Japanese utterance word, I proposed the calculation method as reliability in consideration of the length of utterance word, and 36 prefectures were recognized from 47 prefectures utterance images by the experiment. The recognition rate became approximately 76.6%. In future, I consider a method to improve accuracy to extract the period that the mouth shapes are formed.
