Google Assistant can finally be summoned on iPhones using your voice

Google

• The latest version of Google Assistant for iOS lets you
  summon Google Assistant via Siri.
• You have to say “Hey Siri, OK Google” to open Google
  Assistant. Then say “OK Google” again to use your voice with
  Google Assistant.
• It’s an imperfect workaround, but it helps break down the
  barrier that Apple built around its ecosystem — before now, there
  wasn’t a way to open Google Assistant using your voice on iOS.

Up until Wednesday, the only voice assistant you could summon and
control with your voice on Apple’s devices was Siri, but that’s
now changed with the latest version of Google Assistant for iOS.

In the latest update, you can now add Google Assistant’s “OK
Google” summoning phrase — or your own custom phrase — to Siri.
That means you can summon Siri and ask it to summon Google
Assistant using your voice.

It goes like this: “Hey Siri, OK Google.” Siri will then open the
Google Assistant app, at which point you have to say “OK Google”
again to start asking questions or issuing commands to Google
Assistant. It’s not perfect and it feels a bit like a workaround
rather than an actual feature, as you have to say three phrases
to get to Google Assistant versus the single phrase for Siri or
Google Assistant on Android devices.

To get this to work, you’ll need to update to the latest version
of Google Assistant via the iOS App Store. You might get prompted
to “Add Google Assistant to Siri,” in which case you tap “Add to
Siri” and add the Google Assistant summoning phrase of your
choice. Otherwise, you’ll need to go to Siri’s settings in iOS
and tap “Add OK Google to Siri” manually.

In the past, in order to summon Google Assistant on iOS devices
using your voice, you needed to open the Google Assistant app or
tap a shortcut on the widgets screen.

This is incredibly useful for anyone who uses iOS devices and
Google devices. It’s incredibly useful even if you don’t own
Google devices, as you can now use Google Assistant as your main
voice-activated assistant instead of Siri. In general, this
workaround to access Google Assistant with your voice helps break
down the wall that Apple builds around its products and
ecosystem, and gives iOS users more access to things that aren’t
Apple.

Overall, Google Assistant is smarter and more useful than Siri.
It’s more capable in almost every single way. Funnily enough, the
most useful thing that Siri now does is to summon Google
Assistant — without Siri, there would still be no way to summon
Google Assistant with your voice.
