There are two parts to the system, Navigation and Dictation. The navigation part is continuous speech and the dictation part is isolated speech. The difference is that with isolated speech you have to make a small pause between each word. To see what you can say, or where you can go, all you have to do is say whatcanisay and a list of voice commands appear. These commands are what you can use navigating around your applications and desktop.
Dictation is quite different.
Where you use continuous speech in navigation, you have to use isolated speech. With dictation you have two methods of dictating to your applications if they are not voice aware. You can use the VoicePad or VoicePad Direct. VoicePad is the original method of the software understanding your speech. This looks like WordPad but has many more features and commands, such as Begin Dictation .
