| Research Abstract |
Lip movement sensor senses speaker's lip movement by reflection of infrared light. When the sensor uses on mobile phone, there is a problem that the sensor position is different in each time. In this study, we improved robustness for the sensor position by installing nine lip movement sensors on the mobile phone and selecting the best sensor signal automatically. We achieved 74.1% Japanese fifty words recognition rate only by lip movement under different sensor position by each user. It was 7.2% improvement.
