Using Siri, Apple's voice assistant, you can speak commands to your iPad or iPhone and have it do your bidding. Here's a run down of all the things you can get Siri to do, plus some tips to get Siri to work better for you.

How to use Siri on the iPhone or iPad

If you have an iPad or iPhone (iPhone 4S or newer, iPad 3 or newer, all generations of iPad mini and iPod touch 5th gen or newer) you can trigger Siri in one of these ways:

  • Hold down the Home button 
  • Hold down the control button on your earphones
  • Say "Hey Siri."
  • When you have prompted Siri the background should blur, you'll hear a 'ba-ding' noise and 'What can I help you with?' will appear onscreen.
  • You should also see a wavy white line at the bottom of the screen.
  • Speak your request into the iPad or iPhone.
  • When you've finished speaking, the white line turns into a round microphone icon.
  • Siri should get back to you with an answer (although sometimes it takes Siri a few moments).

On older iPhones (pre-iPhone 6s), you'll only be able to use Hey Siri when you're connected to a power source.

You will also need to have a data connection to use Siri.

How to use Siri on an iPhone X

Since the iPhone X has no Home button to invoke Siri you need to:

  • Hold down the Side button (also known as the sleep/wake/power button). 
  • Hold down the control button on your earphones
  • Say "Hey Siri"

How to use Siri on the Apple Watch

  • Press and hold the digital crown.
  • Say "Hey Siri"

What can Siri do on the iPhone?

Siri is the digital assistant that's built into your iPhone, iPad, Apple TV, Apple Watch, or Mac. You can ask Siri to do something and have your iPhone do it, rather than go through multiple menus or tap through lots of options.

Siri is constantly improving: it became faster and more reliable than ever with iOS 7 and in iOS 7.1 gained new features and a female voice for the UK, iOS 8 added music identification, "'Hey Siri!" voice activation and real-time feedback of the words Siri thinks you're saying. Then, with iOS 9, Apple introduced new features to make Siri contextually aware.

In iOS 10 Siri gained the ability to control non-Apple apps, and at the same time arrived on the Mac (read about how to use Siri on the Mac here). In iOS 11 Siri gained the ability to translate phrases (currently only available in American English) and a more natural sounding voice.

Siri is also a key way to interact with the Apple Watch and the Apple TV.

Siri can be used for the following:

  • Scheduling events
  • Finding locations and directions in Maps
  • Setting a timer
  • Checking the weather
  • Updating statuses on Facebook
  • Sending Tweets
  • Calculations
  • Playing music
  • Opening apps
  • Sending emails
  • Sending Messages

Here are some things to ask Siri:

  • Turn Bluetooth off.
  • Open an app.
  • Post to Facebook and Twitter.
  • What is 20 degrees centigrade in Fahrenheit?
  • How many calories in a Big Mac?
  • How much is a 10% tip on a £38.90 bill?
  • What is the square root of 81?
  • Flip a coin (also try Yes or No? and Roll a die).
  • What time is it in San Francisco?
  • Take a picture.

How to use Siri: Sample questions

Siri can also be your music DJ

You could ask Siri to...

  • "Play the top songs from 1982."
  • "Play more songs like this."
  • "Add the new Blur album to my library."
  • "After this song, play They Want My Soul."

You'll need to sign up to Apple Music to make the most of this feature though.

Siri can be influenced by the context

Siri can take into account your location, the time of day, re-occurring activity, usage patterns, the app you are viewing or other connected devices to anticipate your next move and surface relevant actions and information, before you even have the chance to ask a question or type in a query. So, for example, you could:

  • Ask Siri to "Remind me about this when I get home," when you're on a particular web page that you want to come back later, for example.
  • Ask Siri to "Show me videos I took at Iva's birthday party," "Show me photos from Utah last August," and "Remind me about this when I get to my car."

We have more details about the different things you can ask Siri to do below. Plus, if you are looking for a laugh, read: Funny things to ask Siri here.

How to set up Hey Siri

Apple introduced the always-on "Hey Siri" command back in iOS 8 in 2014 and it means that you can say "Hey Siri" at any time you wish to use the digital assistant.

This means you don't need to press the Home button (or Side button if you have an iPhone X) in order to trigger Siri. Which is helpful if you need to have your hands free. (Or if you are cooking, have dirty hands, and want to set a timer).

It's a helpful feature, but it could get very frustrating if your iPhone answered to everyone. Luckily when you set up Siri you train it to recognise your voice.

Here's how to set up Hey Siri:

  1. First go to Settings > Siri & Search (Previously, Settings > General > Siri).
  2. Make sure Siri is turned on (the switch beside Press Home for Siri should be green).
  3. Toggle the Listen for "Hey Siri" slider on.
  4. This will bring up the setup menu for the virtual assistant.
  5. Follow the on-screen prompts to train Siri to recognise your voice. Make sure you speak as naturally as you can because this is the voice and sound that your phone will be listening out for from now on.
  6. It'll ask you to say "Hey Siri" a few times, and then sentences such as "Hey Siri, how's the weather today?" and "Hey Siri, it's me."

How to type to Siri

You don't have to talk to Siri, if you prefer you can type in your question. Here's how to set Siri up so that you don't have to speak your commands:

  1. Go to Settings > General > Accessibility.
  2. Scroll down to Siri and tap on that line.
  3. Turn Type to Siri on (so that the switch beside the option is green).
  4. Now, when you trigger Siri you will be able to type your request in.

Siri tips: How to get Siri to work better

Having a few problems with Siri? Is Apple's digital assistant failing to understand you? Here are a few tricks you can implement to make Siri do a better job.

Make sure you have a data connection

Siri works by recording your voice and sending it to a server that interprets what you've said and returns plain text. If you haven't got an internet connection, Siri won't work.

Manually control how long Siri listens

You can also manually control how long Siri listens to you for, rather than waiting for it to detect that you've stopped speaking. To do this, hold down the Home button while you say your command or ask a question, and release it when you've finished. (On the iPhone X we assume you can press and hold the side button to achieve this, but that may instead close your iPhone).

Change Siri's language

If you find that Siri isn't understanding you very well check that you have the right language selected. If you use UK English you may get better results if you have English (United Kingdom) selected.

Alternatively, if you want to use features that are only available via the English (United States) version of Siri, such as language translation, you may prefer to use that language.

To change Siri's language go to:

  1. Settings > Siri & Search
  2. Tap on Language
  3. Choose the language you with Siri to use

Note: If you don't speak a language fluently Siri may not be able to understand you. Even the US version of Siri may have difficulty understanding a British accent. And, as you can see from this video, Siri may struggle with some of the UK regional accents.

How to dictatate with Siri

If you are dictating a message or email using Siri there are a few things to bear in mind if you want to get the best results:

To get the most out of dictation, you'll need to start thinking in punctuation. For example, to construct a decent email message, we might say, "David. Comma. New paragraph. What do you think about writing a review of iOS numeral 11. Question mark. New paragraph. Let me know what you think. Exclamation mark."

What to do if Siri misunderstands you

Siri is by no means perfect, and occasionally it can mistranslate what you're saying, either transcribing the wrong message or finding the wrong result from Contacts.

The easiest way to correct Siri is to tap on the place where Siri has transcribed what it thinks you said.

  1. Click on Tap to edit below the words Siri thinks you said
  2. Correct Siri
  3. Tap on Done

How to change Siri's gender

You can also switch Siri's gender: 

  1. Go to Settings > Siri & Search
  2. Tap on Siri Voice
  3. Choose the gender on the next screen

Your iPhone may download the Siri voice you have requested.

Things you can ask Siri to do

Here is a list for some of the serious stuff you can say to Siri with some specific examples.

Use Siri to adjust settings

Siri can access the Settings on your iPhone or iPad, which makes it much easier to quickly make changes.

It's much faster to ask Siri to access settings than it is to dive into the menu.

  • Ask Siri to "Turn off Bluetooth" for example.
  • Or you can just say "Change wallpaper" rather than opening Settings and tapping Wallpaper.

Use Siri to read and reply to messages and emails

When you get a message, you can instruct Siri to read the message, and it will.

  • You can then tell it to reply to the message, dictate the entire message, have Siri read it back to you to confirm that it makes sense, and then send it.
  • You can also ask Siri to read out your Mail messages and it'll let you know who sent you a message and what the subject line is.

Set reminders and alarms with Siri

It's much easier to set an alarm or timer using Siri than it is to unlock your tablet, find the Clock app, and tap within the app.

  • Just say, "Set a timer for three minutes", and your iPad begins to count down until your tea is ready.
  • "Set an alarm for 5am" does what you'd expect, instantly.
  • "Remind me that I need to take my suit to the cleaners".

Use Siri to find out whose iPhone/iPad you've found

If you've found an iPhone or iPad that you can't unlock and you don't know who it belongs to, you can try asking Siri.

  • Say, "Siri, who does this phone belong to?" and you will get their name and an alternative phone number if one is listed.

(I have no idea why I asked Siri to identify Santa Claus is Comin' to Town by Bruce Springsteen...)

Ask Siri about: Sport
