Numerical Analysis of Readable Lip Motion Viewpoint from Hearing-Impaired to Lip-Read

Abstract

In recent years, research on lip-reading technologies using machine learning and image processing has been conducted in Japan and overseas. Many of these research have focused on cognitive methods and cognitive accuracy, but few have focused on hearing-impaired person who is actually communicating by using lip-reading. We think that even speakers with high cognitive accuracy in lip-reading technologies may not be easy to lip-read for hearing-impaired person. Therefore, in this research, we conducted an experimental survey to numerically elucidate how to speak easily for hearing-impaired person who communicate by using lip-reading on a daily basis.
