Save As DAISY XML add-in for Microsoft Word
As mentioned on Mark Harrison's blog;
Microsoft in conjunction with Sonata Software and the Digital Accessible Information System (DAISY) Consortium has released a software add-in to help those who have difficulty reading printed documents to turn Word documents into audio files.
The "Save as DAISY XML" add-in makes it easier to create audio books from text files as an open-source project. It can be downloaded for free, and is compatible Microsoft Word 2007, Word 2003 and Word XP.
