1.- M, P, A, T, S This varies by person. Sometimes there's reason to it (such as letters where you have to put your lips together) other times its just what your stutter wants to do. You could literally just choose random letters if you want to. However, sometimes I have a good day and don't stutter on these. Othertimes I stutter on a word I usually never stutter on. There are also three types of stuttering so this also varies (ofc). Idk the names but there's \- A-A-A-Apple \- Aaaaaapple \- \*random pause/block\* Apple (often sounds forced out) I block a lot, so to the outside it might look like I just don't talk fluidly but it is my stutter. 2. I use (I think) what's called an easy onset. When I'm about to block on a word, I'll try to easy onto it. If you're really invested in this search "fluency enhancing strategies." I'm not an SLP (Speech language pathologist) but there's a classic 6 or so strategies people use. There's a lot of easy to read handouts and I'm sure there are short videos explaining each one. 3. It's annoying. I tell people to assume the stutterer doesn't want you to do it. Might be a stereotype but GENERALLY, people who have had speech therapy/are more confident don't want people to complete their sentences. There are exceptions of course. With close family and friends, they can generally tell when I'm stuttering versus when I just can't think of the word ("normal" speakers sometimes get their sentences finished for them). 4. TLDR at the bottom. I'm generally just saying stuff about the stuttering community. Depending on how important your character is, you can use it or you can't. Thank you for putting in the effort to research the character b4 assuming. It's nice to see people want to represent us. Stuttering changes and comes and goes. You might have your character stutter a lot then randomly stop. I've had months where I rarely stutter then it'll pop up. Sometimes stress worsens it (doesn't cause it though). I say 80% of my stutter is what's brought up by stress and 20% is me just having a speech disorder. We don't stutter in our heads, it's a biological issue (I've heard some people think this). Some days it doesn't bother me, other days I'm just really down. Eye contact is hard to maintain when actively stuttering but it makes me feel good when I can maintain it. I don't care if you say ''person who stutters" vs "Stutterer" vs "she stutters." Other people might prefer one way, I just say "I stutter" bc it's easiest to not stutter on lol. Like all other disabilities, some people make it a personality trait, which is annoying, but the majority of people have other characteristics. This can vary for your character depending on his/her personality and if they're a main or side character. Some people are okay with joking about it, other people aren't. It sounds bad but I would prefer to just have someone laugh at my self-deprecating joke but not continue/say a joke about it. Some people are okay with questions (even from strangers), others aren't. Speech therapy is generally recommended but some people don't want to try it. Good speech therapy isn't just reading off a book. It is a lot of work on confidence and then the techniques mentioned above. Some people are okay with sticking up for themselves while others are just going to hate the person in their head. TLDR for number 4- Everything you might think about a stutterer is probably true for some people. You can choose to have your character have certain ideas/beliefs about their stutter.
