Well...technically it is possible to embed MathML in <formula> tags, and NVDA will read it if you have MathPlayer installed on your PC. But at the moment that is the only AT combination that has built in the necessary support to read such files. An example of such a file can be found at http://msf.mathmlcloud.org/file_formats/8 (look for the link to download the pdf file).

Another issue is automating the process, instead of having to cut and paste all the MathML snippets into your pdf. I had read that Callas Software had been working on this, but I don't know if they ever got it out. I suspect that functionality was supposed to be part of pdfChip, but their documentation doesn't specifically mention the part about automating the <formula> tag output, though it may very well do so. I don't know at this point.

Subject: [WebAIM] Generate PDF including MathML

Hi David,
I don't believe there is anyway to make MathML accessible in a PDF.
You can have MathML in a web page, or MathType in a MS Office document can
be read if the screen reader has a full version of MathType on their local
drive, but I don't know of anyway to make MathML accessible in a PDF. Check
out the MathFinder by Diagram Center for options.
At my institution, we ask instructors who want to use PDFs to keep their
source documents (usually Word with MathType) and if we have an
accommodation, we convert their source documents into HTML or Braille or
simply let the student use the Word doc.
Best of luck!
Karen
