     It depends on exactly what you're asking the users for, but something
like the contents of a voice prompt certainly sounds like 'content' data to

     You certainly don't want to text-to-speech the XML version of the P3P
policy. I would say that in a voice-accessible system, users would expect a
voice-based, "human-interpretable" privacy policy. If the system is both
Web-accessible and voice-accessible, then the Web-side should have a P3P
policy attached.

     Deciding how much data to make accessible is the job of the service
provider, and you certainly shouldn't allow access to personal information
with authenticating the requester. Also, the P3P spec says that "The method
of access is not specified" - it's only that access is required. Thus,
access through only one mode (voice, Web, etc) is certainly acceptable.

     My pleasure. I hope this helps.
