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.
