The Verge reports that you can now use the usual “OK Google” and “Hey Google” phrases to Siri, and from there the Google Assistant can be used just like on an Android device. You can also start Siri up with “Hey Siri”, followed immediately by “Hey/OK Google.”
You can also use Siri to run Google Assistant commands in a smart home. For example, telling Siri “Goodnight Google” will run a routine, such as turning off the lights and locking doors. The new shortcut integration is available by updating to the latest version of the Assistant for iOS. Having said that, it does seem a little awkward to see Siri being used like that.
