When Google released the "OK, Google" hotword to prompt a hands-free voice search, the feature originally worked only on the home screen. An update to the app now makes it possible to launch from anywhere in Android if the screen is on. An update to the Google Search app makes provides an optional setting that can launch Google Now searches from the home screen, lock screen, or any other app. The feature appears to be rolling out to users, but it may not be compatible for older devices. Users can try it out by downloading Google Search from Google Play and ensuring that they are running version 3.5.14.
Also included in the update is a new Audio History feature that saves the recording of what was said. The recordings are kept on hand in order to better learn the user's voice and pronunciation in order to improve recognition capabilities. There are options to browse history, delete items, or turn the feature off completely. Here's a video demonstrating the new "OK, Google" command in action.Droid-Life
