There is a way you can do it.

Download a program called GlovePie (google it).

Find the program or function you want (like your browser, right click the shortcut or exe file and go Properties > Shortcut then in the shortcut key box do something like Ctrl+Shift+I

Open GlovePie and write a script that will look something like this

If said("Internet Browser") then 
     press(ctrl)
     press(shift)
     press(I)
     wait 20ms
     release(ctrl)
     release(shift)
     release(I)
     wait 100ms)
endif

Works like a charm 8)
I use GlovePie for voice commands in games like Unreal Tournament. All I have to say is "Rocket Launcher" or "Shock Rifle" and it changes to it by picking up what I said then pressing a certain key.
