The evolution of voice-controlled search into a virtual personal assistant took another step forward with Google’s announcement that all Android-powered devices (KitKat or above) will now respond to the “hotword” OK, Google.
Users can initiate a search or control and carry out any function on the device simply by saying “OK, Google” first and then asking the question or stating the command: “Call XYZ . . . open my email”:
Starting today, you can say �Ok Google� on your Android device whenever the screen is on or your device is charging. If you�re reading your email, browsing the web or using any app that doesn�t actively use the microphone, saying �Ok Google� will get you the answers you need and let you take actions like set an alarm or call a friend.�Google also allows OK, Google to operate from the lock screen if enabled. Previously the Moto X was the only Android device that permitted this capability.
In my view this is a differentiator for Android devices on the eve of Apple’s move into larger-screen hardware, which will reduce that Android advantage.
Voice control/search will soon be the primary way that users interact with Android devices, especially as the operating system expands into cars, onto wrists and on TV sets.
