If you activate Google's voice recognition from a bluetooth headset, it will respond to you through the headset -- but you often have to interact with the device anyway, to get it to do more than the most simple of things.

Actually next time just try talking to it to complete the task.

I use Google's voice recognition a ton when on my motorcycle with a Bluetooth helmet. I've gotten in the habit of just trying things and to my surprise many have worked.

Play/pause music, mute/unmute voice navigation, ask how long until my next turn, ask it to navigate to somewhere else, call/text/send a hangouts message to a contact by their nickname, play a specific band or album of music, etc...

You also have to be wearing a bluetooth headset, which is as much of a social faux pas as talking to siri in public.

I have Bluetooth headphones, which I'm wearing at the moment as I'm listening to music. They're pretty good at the headset thing too.
