I am running Windows XP Pro SP 2, have Office 2003, installed SDK 5.1,
Visual Studio 2005 with installed .NET Frame 3.0 (re-distribution package).

System.Speech is in .NET 3.0.

C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0

It doesn't contain:
Recognition.DesktopRecognizer
GrammarBuilding.SrgsDocument
GrammarBuilding.SrgsRule
GrammarBuilding.SrgsOneOf

I look at .NET 3.0, they have System.Speech.Recognition.SrgsGrammar.SrgsRule
So my best guess that the namespace/class is a little different?
