OK Google, coming to your Android lockscreen and everywhere else

"OK Google" is creeping into every corner of Google services. First, the Google Now launch phrase was limited only to the homescreen on Android 4.4 KitKat devices but now the voice-activated command will soon be available on any screen, any app and even on the lockscreen of your Android smartphone or tablet. Google is also including a Audio History feature which learns from your voice searches to make detection better.

All these features are coming as a part of the Google Search app update 3.5.14, which is being rolled out on a phone-by-phone basis. If you are eligible then you can simply go to Google Search settings and look inside the "OK Google Detection" menu.
