This software is a custom task pane for Microsoft Word 2007 with VSTO and Visual Basic 2008, which enables Text-to-Speech onto Word documents. You can now open your Word 2007 documents and listen your pc reading. When the new project is created you have to add a reference to the System.Speech.dll assembly, which gives us an API to access the Text-to-Speech engine in a managed way
