1. During fluent lines, include moments of noticeably using coping strategies (ex: slowing down, tapping a rhythm, easy onsets, etc) 2. Stutter on the important bits too. Things we care more about are MORE likely to include dysfluency, but there's a common sentiment that allowing a character to be noticeably disabled during an emotional high point will "ruin the moment". 3. Use multiple types of dysfluency. Repetitions, blocks, elongations, and mispronunciations can all be elements of dysfluency. 4. Don't only stutter in your monologue, but you don't need to stutter on every line either. Very few dysfluent people ONLY stutter during important moments or stutter in EVERY moment. 5. If you're worried about how dysfluency would make a word sound, (ex: the first syllable of "horrible", "assassin", etc.) that is the sort of anticipatory stress that can make dysfluency worse. Don't play it for comedy, but consider that. I often change my pronunciation of those words so I won't be stuck saying profanity, I'm sure others have other strategies. 6. Talk to your co-actors. Dysfluency changes how people react to you, so work with the rest of your cast to find what makes most sense based on their characters' opinions of your character. (ex: Your close friends and family might react as if you weren't dysfluent at all, a condescending stranger might be over-the-top with active listening, an impatient rival might act exhausted every time you open your mouth, etc)
