40 Male Belgian Native language: Dutch/Flemish Other languages: English, French, German Stutter: - before therapy: 93/100 words - after intense therapy: 0-1/100 words on a good day, 20-40/100 words on a bad day I found that my stutter severely increases when learning a new language (or speaking it again after a long time) but decreases with habit and confidence in the language. Essentially, the more mental energy I have to spend looking for the right words, the higher the chance of a stutter. Some additional information: I stutter mainly on hard vowels (k,t,p) and vowels like s,f and so on (don’t remember the correct term). Stutter increases when sick, tired or highly concentrating on another task while speaking. The more mental health energy I have available to focus on my speaking, the less I stutter. Feel free to ask any additional questions you might have (here or DM) and do share the paper once your done with it. I could also bring you in contact with the professor who’s institute treated my stutter in my late teens after I was mistreated by previous logopedists during my younger years.
