Is there a way to use Siri if I can't say "Hey Siri"?

• If you want to activate Siri with a button: Go to Settings > Siri & Search, then turn on Press Side Button for Siri (on an iPhone with Face ID) or Press Home for Siri (on an iPhone with a Home button).

Note: The option to say just “Siri” is available on supported iPhone modelsin some languages and regions.

Use Siri on iPhone - Apple Support

Hello ~ In addition to *Johnathan Burger’s* helpful information…you can also use Assistive Touch to summon Siri…click on below to see more information…

Use AssistiveTouch on your iPhone, iPad, or iPod touch - Apple Support*

*Use AssistiveTouch instead of pressing buttons

The AssistiveTouch menu gives you access to functions that you would otherwise control by pressing physical buttons or moving the device. With AssistiveTouch, you can:

• Activate the Accessibility Shortcut
• Lock the screen
• Adjust the volume
• Summon Siri
• Restart the device
• Capture a screenshot
• Simulate shaking the device

The above are some things you can also do with Assistive Touch and I find it quite useful.
