As the major Android redesign and several new peripherals dominated the announcements at Google I/O, one feature that went relatively unnoticed was the fact that Google quietly updated its search application with a couple of very interesting features.
You will be able to now use the hot keyword, ‘Ok Google’ from anywhere on your device as long as the display is turned on to initiate a voice search and ask for something like the temperature currently without having to manually do anything. This is not a true hotword detection, also known as always listening, that we have seen on the likes of the Motorola Moto X, but it does come pretty close to it. You can use the keyword from within applications, desktop or directly from the lockscreen. Surprisingly, the detection works really well. To make sure that you have the detection turned on, you must go to Settings ->Voice-> And Select Hotword Detection there.
The other new feature added to Google Search is Audio History. Google Now will basically now keep a record of all the voice commands that you have used, for a quick reference or reusing them later on. You can also delete the audio history right off. We are not sure how having an audio history makes any sense, because half the time, it would just contain inaccurate commands that Google Now second guessed because it did not understand our creepy accent. Would it not be better to simply not record what we asked the Voice Assistant?
These features are available in the latest 3.5.14 version of Google Search.
