Google Now is currently the smartest and most responsive voice activated software on the planet, but that doesn't mean it is flawless yet. It still has some learning to do before it can evolve to a higher level of intelligence and take over the world. In the mean-time, on the rare occasions when it doesn't quite get things right, the Google engineers gave it a new feature which gives it another chance to do better.
Now, Google Now lets you say "No, I said... XXXXX" to try again. You simply need to restate what you were trying to do or search for after saying that "No, I said... " line. This word correction feature isn't the only new trick taught to this not-so-old dog. Google Now also lets you control your media with your voice. For example, you can now say “Ok Google, next song” to skip to the next track in your music player. Alternatively, you can say “Ok Google, pause song” to pause playback.
As we have reported earlier, Google Now can also create event cards for your calendar directly from your gmail emails. On top of this it can now better manage call reminders and let you know when to get off your train or bus.
