Accessibility for hearing-impaired users

To provide accessibility for hearing-impaired users, you can include captions for audio content that is integral to comprehension of the material presented. A video of a speech, for example, would probably require captions for accessibility, but a quick sound associated with a button probably wouldn't.

There are several ways you can add captions to a Flash document including the following:

• By adding text as captions, taking care to ensure the captions are synchronized on the Timeline with the audio.
• Using Hi-Caption Viewer, a component available from Hi Software that works in conjunction with Hi-Caption SE for use with Flash. The white paper titled Captioning Multimedia with Hi-Caption SE for Use with Macromedia Flash MX explains how to use Hi-Caption SE and Flash together to create an a captioned document. The white paper is available on the Macromedia website on the Accessibility White Papers page at www.macromedia.com/macromedia/accessibility/whitepapers/. For more information on Hi-Caption SE, see the link on the Macromedia Accessibility Captioning page at www.macromedia.com/macromedia/accessibility/tools/caption.html.
