You can control the Opera browser with voice. You can also make preset voice keys to take you to websites when pronounced. You can get it to read things to you, etc... Pretty neat, and as a bonus it has more features and security than IE and FF together (which is why it's rated #1 of the top 3 browsers).
*Edit: Not sure if this is something useful to you, seeing as your just want stuff to open programs/type for you.
