I don’t stutter, but my friend’s a speech pathologist. She told me that it helps to stutter on purpose a little, as that moves the stutter under your control. Since you are using your agency, it also reduces anxiety. I also recommend going in with a visual aid. The last thing you need is to also be forgetting what you want to talk about. I recommend Beautiful.ai to make a PowerPoint. It’s not just for your audience, it’s for you to keep track of talking points.
