Although Siri doesn't have full access to the Apple Music library of sound effects, it was recently discovered that Siri can play, if asked nicely, the following sound effects (in no particular order): fart, sad trombone, a chipmunk laugh, applause, footsteps, a heartbeat, a laser, a space computer, space, ocean, buzzing bees, shattered glass, a booing crowd, pain, and... silence.
To get Siri to play a particular sound effect, tell Siri to "play the sound of...", followed by any of the above. If you're feeling adventurous, test your luck with other searches, you'll never know what you can find!
As with all tech tools, there's nothing wrong with any of them in essence, it's how the user puts the features into practice that matters the most. You can use Siri's sound effects to become a thoughtful or seriously uninspired prankster. The power is all in your hands, obviously, but will you actually use this feature? If so, share your favorite Siri sound effects in the comment section below!
