If you have your phone language, phone region and phone speech settings all set to English (United States), then you should see Cortana available in your app list. If it is not, go to your Phone Settings and swipe to Applications - you should see Cortana at the very top of the list. From there, you should be able to turn the Cortana feature On or Off.
