Cognitive Experiments of News Captioning for Hearing Impaired Persons

Abstract

The possibility of real-time captioning of news programs was considered for people with impaired hearing. Before we try to realize the system, we need to know the preferred presentation speed and form of the captions. In order to evaluate the intelligibility of real-time captioning, subjects with normal hearing were shown a short news program with captions instead of sound, and their comprehension of its contents was subsequently tested. Results indicated that subjects performed about as well on average after viewing a program with captions as they did after viewing a program with sound, and better than after viewing a program with neither, suggesting that the captions were effective.
