Making Strange Noises...Theres a word for it...Vocal Tics & Aspergers

For quite awhile, I have been searching for the word or term for my various odd utterances...those moments were words escape me and I produce a series of vocalizations, grunts, animal noises, or otherwise strange sounds that are not words. Things such as aarrgh, which I call my pirate sound and tht, tht, tht, tht, in which it sounds like a rapid fire machine gun or phewsh, which is more like a cannonball hitting the water. These are some of the sounds I produce when I get stressed and my word/ verbal center shuts down or short-circuits and I am reduced to mere utterances.
Well,I finally found the name for it: Vocal Tic (also similarly verbal tic or phonic tic)- an involuntary sound produced by moving air through the nose, mouth or throat; VTs include throat-clearing sounds & sniffing to grunts & verbalizations of syllables & words, utterances of inappropriate or undesired statements or obscenities.
There are two types: Simple- single sounds-eg. throat-clearing, barking, sniffing and Complex-verbalizations- expressions of words-eg. coprolalia (from Greek kopros "feces" + lalein "to talk", involuntary swearing or the involuntary utterance of obscene words or socially inappropriate and derogatory remarks), echolalia (repeating of the persons own words), palilalia (repeating ones own previously spoken words)
VTs frequently change and vary in severity and over time remissions and exacerbations are common.
Whew, now that makes some good sense. That is what I have from time to time. I seem to only have vocal tics when I am stressed out or feeling strong, conflicting or overwhelming emotion.
I love it when I find the proper term for things and it drives me nuts when I fail to locate it. Every thing has an appropriate term and once i can find that term, it all makes sense. Its like I keep trying to build this house of cards and if I can't find the word, I can never get to the top...that one level just refuses to stay in place and support the next. Dang, thats a very strange analogy but it is the immediate visual that I experienced..somewhere, deep within my head, it makes sense :)
