When I was running through the Office Communications Server: Speech Server tutorial, Creating a Speech Project [found here], I ran into the following error, which plagued me throughout the runthrough.

Well apparently when creating the project, you were given the option to create custom Lexicons for your Grammar file. If you clear out these files, the solution will build, and you can use the voice response debugging window.

This happens because the MIME Type is not registered for .lex files in IIS, seen in KB938284.
