Step 1: Download Voice Activiation Command Software

I simply googled the term, and Voice Activated Commands came up as the first choice. This program serves a useful purpose in RPGs and other computer games where voice commands can be given rather than typing in key combos. For this project, it can be used to cast "spells" on your computer to manipulate it to do your bidding.

VAC Download Page

It's currently only available for Windows XP and Vista.

Step 2: Grab Some Spells And Plug 'em in!

Picture of Grab Some Spells And Plug 'em in!
For researching all of those tip-of-the-tongue-can't-quite-remember spells, the coolest place I found was MuggleNet. It's the cream of the crop as Harry Potter fan sites go. Their spells section is extensive and gives a description of each spell.

Some sample spells:
  • Brighten Screen
  • Dim Screen
Petrificus Totalus
  • Hibernate
  • Mute
  • Volume Up
  • Stop In Web Browser
  • Exit application

Also, I made an action called "Marauder's Map" which is activated by saying "I solemnly swear I am up to no good." which opens the browser to the home page.

What is a free software I could use for this? When I download VAC it tells me I have 14 days.

I used evanesco to minimize the browser instead, since Reducio wouldn't pick up.

The download link in the instructable is linking to an old page. The correct download page is and the newest download file is

The link in the article is when it should be . So when you go to the old page, it is linking to an old install file which is no longer being served on the server.

I should think that "Avera Kedavera" would probably cause a system crash. Wouldn't it?

What if you used "Stupefy" ?
Stand by

For those of you disappointed for it not having certain functions. Just write a simple c++ app that does the command you desire. Then have VAC execute the app.

C++ is easy to learn for beginners so if you don't have coding experience don't be scared off by this option. Simple programs such as one to do a basic command could be learned in a matter of hours. Just make sure you start off with the classic "Hello World" :D and you'll be fine.

The VAC builder won't open. It says "Component 'MSINET.Ocx' or one of its dependencies not correctly registered: a file is missing or invalid" I've run the repair on the installer several times and i still get this message.
when i start the test, there's an error that said: SAPI falied to initialize. This application may not run correctly. What should I do?
Go to home then back to downloads

expelliarmus.... eject disk...
stupefy... computer crashes
no instead of crashing..........Blue Screen of Death and then a reboot
dude, the damn post is almost a year old. don't bring them back.
bring what back the blue screen of death????????
sectumsempra: big slash appears across computer screen
Not as funny as mine, or stupefy. Doesn't quite work, as that keeps the spell. Spells should make the computer do something, not just graphics.
your right. sectumsempra makes your computer explode
Takes gasoline. Not so good.
 Fidelius: Hides current window.
No, freezes, then runs again.
