Ever since Google Now became a thing, Search has been the go-to voice command hub for all of Android. There has been one nagging issue, however: when using a Bluetooth headset, a long-press of the action button would bring up the tired old Voice Dialer, which is essentially useless for anything other than making a call. What if I just have to know how tall Joakim Noah is while out cycling.
A big update is rolling out for Motorola's Touchless Control app that should alleviate some of the frustrations users have had with its functionality. Primarily, voice commands no longer require you to unlock your phone first in order to work. Yet for safety reasons, emails, texts, contacts, and other private information remain protected behind a lock screen. Speaking of which, users can now unlock their Moto X by saying their PIN out loud (behavior, while cool, I would be very hesitant to recommend).
Utter! isn't the quiet kid in the back of class who only answers a question when asked, pointing out the answer in a textbook like Google Now, nor is it the class clown who dishes out snarky answers whenever he or she doesn't like the way a teacher asks a question, like Siri. Utter! is the student that sits in the front seat and always raises their hand first, the one that has the answer for every question, no matter how it's phrased or what it's about.
