I think the main thing which needs to be in the PDF is structure
'tagging'. Unfortunately, making truly accessible PDFs is the one area
I've found where the 'TeX suite is weak. I was tracking some discussions
about this on  the various TeX and Latex lists and it seems that to add
the necessary information needed to create accessible PDFs requires a
major redesign of TeX internals.

It has been a while since I looked at this, but I do believe there are
some add-on latex packages which can help a bit, but creating PDFs which
meet minimal accessibility requirement tests is currently not possible.

IIRC the speech-disabling feature is not part of the PDF spec. This is
somethinhg added by Adobe (along with other DRM support). This is no
'switch' so to speak in plain PDF documents as the PDF spec predates
considerations like TTS or even accessibility.
