If you have a compatible device (phone, speaker, etc.), you can get Google Assistant’s attention by saying one of two wake words: “OK Google” or “Hey Google.” Then, you make a request or ask a question.
Google Assistant quickly deciphers your vocal instructions using the same technology that powers Google’s outstanding search engine. The reaction time is so fast that you’ll usually get an answer within a few seconds.
If you ask a question, the Assistant gives you a brief answer and sometimes sends the top search result to your phone so that you can learn more.
Google Assistant doesn’t just answer questions. It works with oodles of services so you can check the traffic for your commute and squeeze in a quick yoga workout before you head to work.
