There are many tools you can add to your iPhone or iPad. You can use a case, a pair of headphones, or even a flash drive. But by far, the best help you can get on your iPhone or iPad is Siri. With a simple "Hey Siri," you get many tools and features available to you without using your hands. Start using Siri isn't hard; here's how you can set up Siri on any of the best iPhones or iPads.

How to set up Siri on iPhone and iPad

"Hey Siri," now tries to lock on to your voice to prevent accidental — or mischievous — activation. You can either set it up when you set up your new iPhone or iPad or at any time in Settings.

  1. Launch Settings from your Home screen.
  2. Tap on Siri & Search
  3. Tap the Listen for "Hey Siri switch to turn it on.

Siri now knows your voice and is ready to go!

How to use "Hey Siri!"

Learning how to set up Siri is easy, but using "Hey Siri!" is, by design, ridiculously easier. You say, "Hey Siri," to initiate the start of your interaction.

  1. Position yourself within audio range of your iPhone or iPad
  2. Say "Hey Siri!" loud enough for your iPhone or iPad to hear you.
  3. Tell Siri what you want it to do — "call mom on speaker," "make a dinner reservation," "what's the weather like in Bermuda?" etc.

Here's a list of awesome Siri commands you can test out right now.

How secure is "Hey Siri!" voice ID?

We've tested "Hey Siri!" with over a half-dozen voices, and nothing has worked except the registered voice or a recording of the registered voice, but that can vary. But Voice ID on Hey Siri isn't meant for security. Don't mistake it for "My voice is my passport, authorize me!" Instead, it's intended to solve the problem of unintentional activation, whether it be accidental, a prank, or even malicious.

Turn "Hey Siri" off and stick with manual activation if you're worried about security. If you're interested in the convenience of voice activation while caring for children, cooking, working, or otherwise have your hands full, then know the limitations but enjoy the functionality.
