Are we in agreement that we discussing only audio that meaningful content? I am thinking of a typical RealAudio archive of a radio broadcast. P1 is met by providing a transcript. With the very reasonable points made about residual hearing, English as a foreign language, learning disabilities, etc., P2 (significant barriers) seem fair to me for these groups. With the points raised (additional audiences served by live captioning), I would now argue that for multimedia (video w/ voice) that P1 *requires* captions (and that mere transcripts are not good enough). The Deaf are so comfortable now with synchronized television (and movie) captioning that IMHO a separate transcript is not much of an accommodation. Does SMIL support captions for ReadAudio broadcasts? Does anyone have examples of synchronized captions for audio-only content? -- Bruce Bailey On Friday, December 10, 1999 4:05 PM, pjenkins@us.ibm.com [SMTP:pjenkins@us.ibm.com] wrote: > I would argue that even priority 2 is too high.
