HOWTO download OCS 2007 Speech Server

I had a heck of a time finding the downloadable version of the OCS 2007 Speech Server component, which you can use to build interactive voice response (IVR) and text-to-speech (TTS) capabilities into your own applications. We use it extensively in the UC Metro training, and I needed to reinstall it– but it was nowhere to be found.
Cut to the chase: it’s available at http://www.microsoft.com/downloads/details.aspx?FamilyId=BB183640-4B8F-4828-80C9-E83C3B2E7A2C&displaylang=en. Don’t try searching for “speech server 2007 download” or you’ll only get some old, obsolete microsoft.com pages that offer a broken beta version.
