This article explains how to use Siri on iPhone 13: Using Siri on iPhone 13 works pretty much the same as using Siri on other iPhones. The following steps work on all iPhones running iOS 15, the version of iOS that launched with the iPhone 13.

Before you can use Siri on iPhone 13, you'll need to make sure Siri is set up on your iPhone. To set up Siri on iPhone 13, open Settings > Siri & Search.

Turn on Listen for “Hey Siri” if you want to control Siri with your voice. Turn on Press Side Button for Siri if you want to control Siri with a button.

If your iPhone is listening for voice commands, saying “Hey Siri” will open Siri and prepare your iPhone to ask a question or issue a command. Be sure to speak clearly around your iPhone, but also know that iPhones have traditionally been good at picking up voices.
