Google Assistant will now cease talking if you simply say 'stop'
 

You can now get Google Assistant to stop talking with just one word: "Stop." That's it — you don't even have to say "Hey, Google" before that. The official Google Twitter account has announced the small but necessary quality-of-life improvement for the company's speakers and smart displays. It sometimes takes a while (and several repeated attempts) to get Assistant's attention with a "Hey, Google" if it suddenly goes off without you wanting it to or if you absolutely have to cut it off mid-spiel. This new feature solves that problem.
