    I am trying to find out how to tag super and subscripts in a PDF file.

      When I convert documents from Microsoft Word to Adobe PDF files, the process works fine. However, when I set the reader to read aloud, it reads the superscripts like a regular number rather than a superscript like in HTML code. Am I missing the proper way to tag super and subscripts??

          Sorry, I do not know of any way to automate this - although one of the advanced tools like CommonLook might have this capability. If the super and subscripts are something other than references, substitute <Span> for <Reference>.

            PDF tags / elements are identified in the sub-clauses of clause 14 in the PDF reference (ISO 32000-1). In part 1 of this ISO standard there is no tag/element for superscript or subscript per se.
