Hi! I'm a Speech Language Pathologist, and I think you did a fantastic job with your presentation. Did you stutter? Yes, but you stuttered very naturally, it didn't seem like there was a lot of pressure or force being used to get through the stutter, you just let it happen and moved on! I think it was great that you disclosed your stutter at the beginning of the presentation. Often, people who stutter will use covert behaviors to hide their stutter as if it's something to be ashamed of. It's nothing shameful, it's part of you and your communication experience, and disclosing that you stutter can release some of that shame and help your audience understand. Side note, I also think you have a very nice voice and I'd love to hear you give more presentations, or maybe even narrate an audio book from the perspective of a person who stutters!
