I make a lot of sounds, but I don't really consider them stims because to me stims are things that give me an endorphin rush, which I don't get from most of them?
The exception is counting/chanting "one-two-three-four, two-two-three-four, three-two-three-four, etc..." or "one-two-three-four, five-six-seven-eight, one-two-three-four, etc..." both of which I do pretty frequently, generally while stimming with my hands, and calm me down a lot.
My brother used to make fun of me because sometimes I would get distracted and just sort of go "aaaaaaaaaaaaaaaaaahhhhhhhhhh" for a long time, doing weird untranscribable things with my voice. Other times I "tick" my tongue, or repeat words over and over, and sometimes I chant or sing nonsense rhymes. When I'm walking or driving, I sing to myself. And I make cat sounds a lot, or mutter or babble to myself.
