Real-time Captioning System for Hearing-Impaired Students

抄録

In this research, we developed a caption system which converts the voice of the speaker in classes, lectures and events at the university into captions in real time and presents them to the hearing-impaired students by means of voice recognition technology, wireless LAN technology, and computer summary transcript technology. A field test in university classes revealed that this system could convert the voice of teachers to captions with a high accuracy of 93%. Unlike conventional speech recognition methods, there is no need for a specially trained person to repeat the speech, and so the system has higher practicability.
