You can't directly delete Siri from your iPhone, iPad, or Mac. Siri is an integral part of Apple's operating system and is not designed to be removed.
However, you can disable Siri and prevent it from responding to your voice commands:
Disabling Siri on iPhone and iPad:
- Open the Settings app.
- Tap on Siri & Search.
- Turn off the toggle for "Listen for "Hey Siri" and "Press Home for Siri."
Disabling Siri on Mac:
- Open System Preferences.
- Click on Siri.
- Uncheck the box for "Enable Ask Siri."
By disabling Siri, you prevent it from being activated by voice commands or by pressing the Home button. You can still access Siri through the Siri app or by typing your requests in the Spotlight search bar.
