Audio Descriptions for Video

Overview

Closed captioning does not make all videos accessible. Audio descriptions (short verbal descriptions of visual actions or key visual scenes, such as the setting, costumes, and facial expressions) may be used to convey context to someone who is visually impaired or blind. Is there enough description that you could close your eyes and follow the instructions or explanation? Audio descriptions may supplement what is available in the original recorded audio track. The Boise State Educational Access Center may provide additional resources for audio description.

The Described and Captioned Media Program (DCMP) holds the standards for described and captioned media. It is funded by the U.S. Department of Education and provides a variety of resources to serve students with sensory disabilities. The Described and Captioned Media Program Description Key provides examples of what to describe.

Tips for narration in videos:

• Try listening to the video with your eyes closed. Is the audio sufficiently loud and clear? Are images, questions, or equations adequately described aloud? Is an explanation of what is happening on the screen provided? Are references to “here” and “there” replaced with more specific descriptors? Is the final answer stated aloud? Consider how these small changes can improve instructional clarity for all students.

• Describe the sequence of actions, first.

• Several brief tutorials for video instruction in math demonstrate how to ensure visual aspects are as accessible as possible.
