SharePoint Thoughts

I’ve decided to bite the bullet and get some more information on Speech Server, forums and blog posts are great, but sometimes you just can’t beat a book. So I went ahead and got Pro Microsoft Speech Server 2007 by Mike Dunn, and I’ll post some more information on the book here as I read through it.

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.

RESOLUTION

To resolve this issue, follow these steps:

This solution was found using the MSDN Forums, quite a useful resource.
