Book excerpt: The work of writing closed captions for television and DVD is not simply transcribing dialogue, as one might assume at first, but consists largely of making rhetorical choices. For Sean Zdenek, when captioners describe a sound they are interpreting and creating contexts, they are assigning significance, they are creating meaning that doesn t necessarily exist in the soundtrack or the script. And in nine chapters he analyzes the numerous complex rhetorical choices captioners make, from abbreviating dialogue so it will fit on the screen and keep pace with the editing, to whether and how to describe background sounds, accents, or slurred speech, to nonlinguistic forms of sound communication such as sighing, screaming, or laughing, to describing music, captioned silences (as when a continuous noise suddenly stops), and sarcasm, surprise, and other forms of meaning associated with vocal tone. Throughout, he also looks at closed captioning style manuals and draws on interviews with professional captioners and hearing-impaired viewers. Threading through all this is the novel argument that closed captions can be viewed as texts worthy of rhetorical analysis and that this analysis can lead the entertainment industry to better standards and practices for closed captioning, thereby better serve the needs of hearing-impaired viewers. The author also looks ahead to the work yet to be done in bringing better captioning practices to videos on the Internet, where captioning can take on additional functions such as enhancing searchability. While scholarly work has been done on captioning from a legal perspective, from a historical perspective, and from a technical perspective, no one has ever done what Zdenek does here, and the original analytical models he offers are richly interdisciplinary, drawing on work from the fields of technical communication, rhetoric, media studies, and disability studies."
