A fair number of you have probably used the ridiculously simple (and bizarre) workaround to get Okay Google Everywhere working on your device without waiting for Google, but there's a catch. If you turn on the lock screen functionality, it makes your phone a little less secure.
Not only is Google announcing all sorts of stuff today, but it's also updating a slew of its apps (it is Update Wednesday, after all). Today's Google Search update brings a huge improvement: "OK Google" hotword detection to any screen... even the lockscreen. If you're plugged into a charger, the feature will even work with the display off. This lines up with the earlier rumor that it was coming eventually.
Once enabled (Google Now > Settings > Voice > "Ok Google Detection"), you'll have to enable Audio History and say the words three time in order for Now to register your voice – much like setting up the hotword detection on the Moto X and recent Droid devices.
It looks like the "OK, Google" search hotword has now become a standard feature for advanced Android launchers. Nova Launcher added the search function in its 3.0 update earlier this month, and now its biggest competitor, Apex, has followed suit. Users who are on Android 4.4 can enable the voice-activated search function in Apex Launcher 2.4. Earlier versions, sadly, cannot access the functionality - you'll have to search with your fingers like some kind of sad troglodyte.
Action Launcher developer Chris Lacy has rolled into the latest beta a feature that just appeared in Nova Launcher two days ago. After signing up for the beta and getting everything good to go, just hop over into the app's settings to toggle the feature on. From then on, you can say "OK Google" from the homescreen to have it pull up a Google search a la the Google Now Launcher.
Google's voice search feature has been slowly but surely working its way into more mobile products recently. First the hotword came to the search app, then to the search results. The Moto X launched with always-on listening, and the Nexus 5 now has voice commands from anywhere on the homescreen or in the search app. Now the "OK Google" command is coming to the desktop via a new Google Chrome extension.
Easily one of the coolest features of the Moto X (and its sister DROID devices on Verizon) is the Touchless Control function, which allows users to say "OK Google Now" from anywhere and activate voice actions. That functionality is built in to Android 4.4... with some rather hefty limitations.
First of all, the "OK Google" command will be hardware-dependent. Google isn't saying exactly what the required silicon is, but at the moment, only the Nexus 5 will have access to the feature - even the other Nexus devices due to be updated won't be able to join in.
