For example, try your activation catchphrase, then say, “PlayStranger Thingson [service].”
Other services like YouTube also let you play videos with your voice.
Say your preferred catchphrase, then “Pause,” “Play,” or “Resume.”
These commands work even with services not currently logged into through Google Home, like Hulu.
Use your catchphrase and say “Stop” when you’ve finished listening or watching.
Scrubbing through a video youre watching with your voice is also straightforward.
If you want to mute it altogether, say “Mute.”
you could follow that up with “Unmute” when youre ready for the sound to come on again.
Say, “Hey Google, turn on [rig].”
