Google Now hands free
Get all of the features of Google Now, from anywhere on your phone, simply say "Okay Google" or wave your hand to activate.
What does this mean?
Google Now becomes more conversational as after a search just say "Okay Google" to start a new one. And even better get the answers to your questions while your hands are tied, or when you're on the couch, or in the car.
Tomorrow's Features Today
Everybody's talking about the new Touchless Controls features for the Moto X, but now any phone that is running Jelly Bean or higher can have the same experience.
Open Mic+ will run in the background and can be configured to start at boot so that it truly becomes part of the phone.
Open Mic+ uses offline voice recognition which means less data usage and faster results.
