Presentation Speed and Vocabulary in Closed Captioned Television

Written by Dr. Carl Jensema and Ralph McCann in 1995, this paper addresses concerns regarding broadcast captioning, such as whether programs are captioned verbatim, how much editing is done, and what the presentation rate is. One hundred eighty-three prerecorded programs were selected for research. Includes tables that show the original script, words removed, words added, and the final captioned script of various programs. Also includes a list of the most frequently used words, with percentages, from the combination of the television programs used.
