{Further advances toward Tagged \PDF\\\ for~mathematics} {Ross Moore} {This is the 3rd presentation on on-going efforts to develop the ability to generated Tagged \PDF\ output using pdf\TeX, in conjuction with other software tools. In this talk I'll show how recent improvements to Adobe Reader and Adobe Acrobat Pro software have increased the usefulness of Tagged \PDF\ documents, containing a \MathML\ description of the \TeX-typeset mathematical content. In particular, by careful specification of the words to be ``Read Out Loud'', mathematical content can be conveyed quite effectively to the visually impaired. Also, using Adobe's Acrobat Pro as the \PDF\ browser, the ability to export to \XML\ means that a fully marked-up, with \MathML\ for the mathematics, version of the \PDF\ document's contents can be obtained at will from the same file that displays the high-quality typeset visual appearance. Examples will be shown of diverse mathematical content, generated automatically from standard \LaTeX\ coding, along with suitably generated \MathML\ descriptions.}
