1. Both, my stutter has a mind of it's own. 2. Vowels, the letters W, K, C and any letter that is followed by a long vowel tend to trigger my stutter. 3. I have never paid attention to it. 4. I experience shortness of breath, during and after I stutter. 5. When I am singing/rapping I normally do not stutter. Reading is a whole different scenario. I have never been able to read out loud in public fluently except one time in third grade. (I am currently 21.) If I am reading privately, I tend to not stuttering 6. In casual conversations I tend to use filler words such as "and" or I \[un\]intentionally developed this ability to forget something or someone's name. There's a 99.9% I know what I'm trying to say, I just do not feel like dealing with the shortness of breath tbh. 7. I personally find this question complicated because there is a lot of elements that determine if I swap words out. I struggle saying my siblings name so that is the only instance where I intentionally swap them for a nickname.(Ex. The Beast, Yzma, Bumi, Linda, The Boy, Ding Dong, ETC.) I tend to speak AAVE the majority of the time since it does not cause me to stutter as much. Unless I am in a professional/education environment, AAVE is commonly used. Growing up in a Nigerian household has influenced me use more British English vs American English (Boot vs Trunk). Basically, what ever words that come out my mouth and is understood by my target audience is all I care about.
