Do you store the sounds and speech in your body before you make them? Or do you create the sounds/speech as and when you desire? When a balloon pops is the sound “stored” in the balloon “escaping”? This is probably similar (not identical) to what you’re asking (although subatomic particles don’t have “desire”)
It seems like something is created out of nothing but a lot of what we call “particles” are, in the modern interpretation, excitations in different fields. This is the weird and wonderful world of modern physics.
