Siri is a virtual assistant developed by Apple Inc. that first appeared on the iPhone 4S in October 2011. Siri can be used to perform a variety of tasks, such as setting alarms, sending messages, and searching the web. However, some users may find that they do not need or want to use Siri, and may wish to switch it off.
There are two main ways to switch off Siri. The first is to go to the Settings app on your iPhone or iPad and tap on “Siri & Search.” From here, you can toggle the “Listen for ‘Hey Siri'” switch to the off position. This will prevent Siri from listening for the “Hey Siri” wake word and activating. The second way to switch off Siri is to go to the Control Center and tap on the Siri icon. This will temporarily disable Siri until you tap on the icon again.
