Siri has been Apple's built-in voice assistant since the iPhone 4S launched in 2011, and its dry robotic delivery became comedy material almost immediately. Short samples of the Siri voice circulate on soundboards, TikTok and meme edits, where they stand in for any unhelpful AI. Much like other notification sounds, the clip works because everyone recognises it within half a second. It still shows up in phone prank videos, 'asking Siri' trends and skits about talking to technology.
