There are actually three types of NLG: The end is obviously the part everyone is waiting for but it is just too hard to get there. It is going to be one long journey before you arrive in the end but it is going to be all worth it. NLG was actually used to make Siri, the voice command prompt found in the latest editions of iPhones. It is a feature that is indeed amazing but needs an Internet connection to make it work. Siri can answer anything from the date, time, and even the meaning of words that you can’t understand. The latest edition allows you to make calls just by telling Siri. This feature is definitely for all those lazy people out there who want to make life easier and that is exactly the goal of NLG.
