ROKTalk voicing can be applied effectively to Flash-based pages or page elements using the API. It is straightforward for this to be applied to Flash production processes, or recompiled into existing Flash content. User interface and control actions can be deployed as required.
Flash presents one of the most interesting challenges to accessibility. Not only is it less easy to acquire its content (parsed or otherwise) using client side scripting, its content is often highly dynamic (and media rich).
We have adopted an approach analogous in reasoning (if not method) to that of W3C's WAI-ARIA and how it deals with the same challenge regarding DHTML, most specifically WAI-ARIA live regions.
Rather than try to use a generic means of reading the highly dynamic content (a near impossible task as what dynamic content should be read, and the priority order of audio output is not semantically implicit) we offer a simple yet powerful means (an API) for the Flash developer to very easily voice content on event of their choosing.
The developer can then make the decision regarding what should be read and when, and at a logic level.
