Captioning Key - Captioning Presentation Rate Research

Captioning Presentation Rate Research

This appendix is a research document which contains a conglomerate of studies related to both children and adults and how they view, read, and prefer captions. Initially, it seems to be common sense that verbatim captioning is the ideal, the mark of true equal access. However, it may be possible for spoken audio to be delivered so quickly that most people cannot read its verbatim captioning, which seems counter-productive to the goal of equal access.

Additional research is needed to determine how fast captions should appear on the screen and what presentation rates people prefer. These critically important issues have only partially been addressed. But there is an existing body of research and study that supports the DCMP policy and philosophy. Much of this documentation can be reviewed in its entirety from the Learning Center. Notes on these studies follow.
