It effects everyone differently from rates, to severity, to central areas of difficulty. Personally, I struggle with a lisp, stutter, AND cluttering. All three have been present in my life ever since I could talk. I remember taking speech therapy from kindergarten to 6th grade. I struggle pronouncing words that end in -th like bath, math, fifth, etc. It used to be all words with -th like the, that, and three as well but I worked past that. My stutter occurs at normal conversations but it is far more likely to occur if I’m stressed, anxious, excited, or tired. (ESPECIALLY anxious and excited) From entire words to syllables, I get caught in words and if I catch myself, I often find myself stopping, taking a deep breath, apologizing for my mistake and try to correctly express my words. It fascinates my friends who hear me sing and notice I never stutter. My cluttering is how I describe my brain working faster than my mouth. I speak a sentence and as if it was spoken three times quicker than it shouldve, all the words got mushed together into some mess of sounds that nobody understood but myself. If I’m anxious or talking in a whisper, it’s more likely to happen. Sometimes I talk to myself at a volume that my friends can hear me (kind of like me talking through my thought process but almost rhetorically where I let them hear me think) and they say “what did you just say...?” And I realize I was talking out loud and although my brain took everything perfectly fluently, my mouth spoke so quickly that anyone listening would have heard nothing understandable.
