Google has updated its Google helper application to support Siri shortcuts on iOS, which will bring support to Siri Shortcuts to make it easier to access your assistant, where you can set up Siri shortcuts for phrases you use frequently with the helper. For example, you can tell "Goodnight" and then the phone will set itself up.
You can also program "Hey Google" as a shortcut to launch the Google Helper application, and after running the app, the helper will listen to you immediately. This means you can say "Hey Siri, Hey Google" and wait a few seconds for the Google Assistant to open directly and talk to it.
You can get the new shortcuts incorporated by updating to the latest version of the iOS Helper application, or installing the app from the Apple Store.
