Google assistant is an artificial intelligent, that is powered by a virtual assistance developed by google that is available on android smart phones and smart home devices.
Google has been working on many ways to make payments secured and easier on different devices.
The Google assistant normally uses voice recognition which google calls voice match. This feature is able to know the differences between the owner’s voice and other people’s voice. Google assistant hides valuable files from the voice it cannot recognize.
