Windows Vista's built-in speech recognition tools are seriously powerful and convenient, as Adam demonstrated by controlling his PC with his voice, but, as he noted, the process for adding seriously helpful macros to the "technical preview" macro tool isn't quite apparent. Luckily, Rob Chambers of Microsoft's speech division has posted a guide to editing, saving, and enabling speech macros in Vista. Good thing, too, because his own blog has lots of geekily awesome macros available for free copying: a Windows Media Player controller that lets you say something as casual as "Play something by Led Zeppelin"; a simple "Send email to ..." Outlook macro; and many more. Got some of your own favorite macros? Post 'em up in the comments. Thanks, Al!
