Hi! First of all, great initiative! I'm on mobile, which makes it impossible to see your post as I'm commenting, but I'll attempt a few answers and hope I didn't forget anything. Stuttering varies lot from person to person. Differences can include the frequency/severity of stuttering and what the main triggers are. As far as I'm aware, these differences don't really correlate with the cause of the stutter (so I don't think your character would have a special set of symptoms), but I could be wrong! I'm curious to read the answers of anyone with more expertise in this particular topic. A person will often alternate between periods of fluency and dysfluency. Personally, I sometimes have bad days/weeks/months where it seems like I stutter more than usual, and good days/weeks/months where I'm remarkably fluent. Also, while it's a myth that stuttering is caused by stress or nervousness, those can definitely play a big role in triggering a stutter, and speaking to anyone who causes these types of feelings can often make stuttering more pronounced. Speaking to a familiar person who makes us feel at ease often has the opposite effect. Stutterers often don't stutter in specific circumstances like when singing or talking to themselves in an empty room. There are exceptions to this, but it's true for many of us in most circumstances. Some people have specific sounds which regularly trigger their stutter, while others have no discernible stuttering pattern. One thing that's challenging for most stutterers is introducing ourselves (it's very common to block on one's own name). I would definitely say that stuttering occurs somewhere in the mouth/throat region, though it's hard for me to pinpoint which parts are responsible exactly. As I'm thinking about what I want to say, before I even start to speak, it feels like there's *something* that's going to block the sounds from being articulated properly. Sometimes I manage to push through this mysterious blockage with minimal perturbations, but other times trying to force it will result in just a series of strained sounds, or even no sound at all. The entire time this is happening, the words are in my mind - I just can't push the sounds out. One thing to note is that stutterers will often try to hide their stuttering if they can - it's not particularly healthy and I wouldn't recommend it, but it can appear necessary at times or just be an instinctual reaction. Even someone who doesn't mind their stuttering being known may try to avoid stuttering in any instances where they can do so, for a few different reasons (one of which being that it can feel embarrassing to stutter, even in front of people who accept you). For this reason, people will often subtly change their sentences to avoid words that may trigger them. They may also just not speak at all if they feel a stutter coming on. Of course, folks with a particularly heavy/severe stutter usually don't have the luxury of hiding it, but they may still (unfortunately) go silent in many instances where they would rather have spoken up.
