Okay, I’m glad to hear that you feel confident while presenting. I’m also sorry that you got called names and people judged your stutter as a merit of presentation. I hate it whenever people mistake my stutter as perceived insecurity or nervousness. I don’t know if I have any tips because I still stutter and everyone’s stutter is very different. I just got to college and I have been forcing myself to make small talk with a lot of people, and I think that from all of the talking, my stutter has improved. I’m wondering if you can speak slower than you normally would? Maybe you can incorporate visual aids on a screen or handouts to the audience? That way, it can maybe take the pressure off of you speaking alone. Hope this helps
