It's only been seven years since Siri made her first appearance on the iPhone 4S and whilst she was arguably the first ubiquitous artificial assistant, a whole mess of imitators have since cropped up.
Google's very own Android-based Assistant is generally considered the main competitor to Apple's Siri but up until recently the voice assistant you used was restricted entirely to the device you owned.
Once done, you can trigger Assistant by simply saying "Hey Siri" followed by the voice phrase you recorded.
Once you're all set up, you can then create Siri Shortcuts which call on Google Assistant Routines you've already created. That means you can now trigger the Google Assistant by saying "Hey Siri, OK Google". Now, Google has updated its Google Assistant app for iOS which will make use of Siri Shortcut.
So if you could give the gift of hands-free Google anytime, anywhere in the house, why wouldn't you? for Black Friday, which is basically half off.
You can also set up other custom Google Assistant routines. If you've turned on Siri support from the lock screen, your iPhone or iPad needn't be unlocked or the screen even on for that to work. Then the Google Assistant app will come up and listen for your next command. Moreover, Google is consistent;y upgrading its virtual assistant so users can derive maximum utility out of it. Now, if you are driving down the parkway, you can just say "Hey Siri, Okay Google" and ask it what you want to know.
If you haven't updated the Google Assistant app on the iPhone, be sure to do so in order to take advantage of the new feature. When you open the Assistant app post-update you should see the option to register it to Siri Shortcuts.
