iOS 15 Siri processes voice recognition on-device for device controls, other queries

Thanks to advancements in machine learning, starting in iOS 15, Siri will now respond to users' requests even without internet access.

Usually, Siri captures a voice request and passes data to a server to respond. With an update to iOS 15, Siri will work in a limited capacity without an internet connection. Users will be able to make specific requests via voice to control the device or execute Shortcuts.

Siri will control aspects of the device like Wi-Fi, airplane mode, dictation, and app control without an internet connection. All commands will be processed on-device, and the user's privacy will remain a top priority.
