Thanks for the advice so far...

I went to C:\Perl\html\OLE-Browser\Browser.html as requested and looked at the Register method. Here's the only information that popped up:

Sub Register(pszSite As String)
Register application with Voice Commands.

If you look in the MasterHouse code, his call to ->Register() looks like this:

$vcmd_ms->Register("Local PC");

... athough I think he pulled "Local PC" out of his bottom. I tried the same thing and it didn't work. The microsoft speech API added a "speech" control panel widget. I looked at it, and everything checks out.

I also downloaded something called "COM Explorer". It lists the 'Voice Command Object' under EXE Servers. It doesn't show any missing dependancies or any other obvious trouble with it.

Thanks! Perhaps I'll try to register the voice command object using Visual Basic Script. It's been a while since I did that! :-)
