The phrase “ok google” isn’t a whole lot to say, but repeating it can be annoying especially if you’ve got a sleeping person near you. Fewer words, the better.
The folks over at 9to5Google have a teardown of some functionality that’s being developed in Assistant called either Guacamole or Salsa (build name varies,) that will allow you to just ask for things like “turn the lights on” without having to say OK Google first.
It appears you’ll be able to individually select the types of things you want a google assistant-enabled device to listen for, such as if you’re never wanting it to potentially accidentally hear “what’s the weather” you can disable or enable one by one.
Voice match appears to be a must for this, and a compatible device, which will probably be most of the Google Assistant enabled devices out there although you never know. You’ll also be able to choose which devices get the functionality so if you don’t want a device to accidentally pick up “skip this song” in your living room while you’re watching a talk on IPA lisp dipthongs, you know, you don’t have to have it listening in the TV room.
No idea when it will launch, but it’s got some great potential.[9to5Google]
