Siri has been Apple's voice assistant on iPhone since its debut on the iPhone 4S, and its distinctive synthetic voice quickly became shorthand online for a phone talking back. Short Siri clips circulate widely on soundboards and in short-form videos, where creators reuse them to stage fake conversations, prank friends, and add a deadpan machine reaction to human silliness. Because almost everyone recognises the voice instantly, even a brief confirmation still works as a joke without any explanation.
