Caption Features for Indicating Non-speech Information: Research Toward Standardization

Project funded in 1996 by the U.S. Department of Education Office of Special Education Programs and Gallaudet University. Studies the variations in captioning conventions for conveying non-speech information (NSI). NSI includes: identification of speaker, sound effects, music, manner of speaking, audience reaction, and indication of a title (book, film, newspaper, play, etc.). A total of 189 deaf and hard of hearing consumers in the study confirmed the importance of consistent presentation of this information. One implication that pertains to presentation rate is that while NSI is crucial in conveying information about plot, humor, mood, or meaning of a spoken passage, it does add more written language for the viewer to process. Pictures of the captioned clips used in the study are included.
