OK Google!

It is a new type of application that interfaces with Google Assistant and is based on a voice-designed interface. When a user tells Google Assistant to use a specific Action, Google will search the Actions On Google platform for an Action with the corresponding name. The user is then guided by Google Assistant to the Action's interface. From this moment, the role of Google Assistant shifts to assisting with voice recognition and information transmission. The task of recognizing user intent and providing appropriate responses is handled by the developer's Action.
