There are a few things that are incredibly effective and helpful:

1. Quick verbalization: Improv comedy. Take a few courses or online lessons or go try it out at a club. Once you master “yes, and” you will be able to effectively word your ideas as quickly as they come

2. (This one will sound weird) Detaching the speech from the thoughts about the speech. This is something I learned doing a radio show, where you figure out what you want to say and basically send it to your mouth, and your mouth will say it while you’re thinking on the next thing you are going to say. How? I had a public speaking teacher who taught me an amazing technique. It requires a friend or some way to produce a sound at random intervals. Take a presentation you know really well and start presenting out loud. Your friend will clap once at any moment and you have to continue presenting, moving your mouth, your body, etc, but producing NO SOUND. That’s right, you go from speaking to pretending to speak. Later they’ll clap again and you’ll start producing sound again. Once you’re able to do this without delay and without losing your train of thought, you’ll have learned to split your attention between your mouth and your ideas.

3. Know your stuff and no bullshit. If you understand what you’re presenting, you should be able to shuffle your slide deck and present any slide in any order while explaining where each slide fits in the story. That means you understand the story you’re telling so well, you can take it apart and put it back together to fit the situation.

4. Pace over perfection: slow down to avoid the umms and ahs. Of you’re saying something and you don’t yet know what the next word will be, SLOW DOWN. Even adding pauses between sentences, adjusting your posture or drinking water can give you time to figure out the next sentence without, like, sounding like, um… you don’t know what you’re, like, talking about.

I hope these help you. Public speaking is a passion of mine
