In Windows Phone 7.x users can already interact with thier phone using the voice. This is done by pressing and holding the Windows key and giving the phone a voice command e.g. “Start [appname]” or “Open [appname]“.

This post will cover how easy you can implement voice commands in your app. Source code is provided at the end.
