Yes and No.
That may sound like a contradiction, but after decades of working with executives, engineers, entrepreneurs, and leaders preparing high-stakes oral presentations, we've learned something important. The way you write is not the way you speak. Most of us were taught to write before we were taught to communicate professionally. In grade school, your teachers asked you to write book reports, essays, and research papers. Those assignments had a specific purpose. They were designed to be read. An oral presentation is meant to be heard, understood, and remembered. That's why so many smart, accomplished people struggle when they sit down to write a keynote, investor presentation, board presentation, or executive briefing. They have the cart before the horse.
Audiences Feel the Difference.
If writing everything down first makes you comfortable, that's perfectly fine. There is value in organizing your thoughts on paper. Writing helps clarify ideas, identify gaps, and create structure. But don't stop there. Once you have your first draft, go back and find the moments that matter most. Highlight the key ideas, the stories, the insights, and the phrases that sound like you. Then put the script aside. Now just talk. No notes. Explain those ideas as if you were sitting across from a trusted colleague or friend. Don't perform. Don't try to sound impressive. Simply communicate. Record yourself if necessary. Listen back. You will often discover that your best lines were never written, they were spoken.
Science Behind Speaking in Public.
There is science behind why this works. Modern neuroscience shows that speaking and writing rely on overlapping but different brain processes. When we speak extemporaneously, the brain engages a complex network involving language formulation, memory retrieval, emotional processing, and real-time feedback. Research in cognitive neuroscience has identified areas such as Broca's area in the left frontal lobe as being heavily involved in speech production and language formulation. The brain's motor regions help coordinate the physical act of speaking, while auditory-processing areas monitor our own voice and help us adjust as we communicate. Executive-function networks help us organize thoughts, choose words, and adapt to the listener in real time.

Speaking in Public is Connecting.
Your brain is constantly creating, adjusting, and responding. Writing is different. When you write a presentation, your brain shifts toward planning, editing, structure, and precision. You have time to stop, revise, delete, and rethink every sentence. That is valuable—but it can also remove some of the natural energy and authenticity that make communication powerful. This is why great Executive Communications are rarely just about having the right words on a page. They are about finding the right ideas, the right stories, and the right human connection. We have helped many, many leaders move beyond reading presentations and toward delivering messages that connect. Because the Board of Directors does not want to hear a document. Investors do not want to hear a script. Employees do not want another corporate announcement. They want clarity. They want to understand why something matters.
Corporate Storytelling. What the Hell is That?
The best communicators are not actors memorizing lines. They are experts who understand their message so deeply that they can explain it naturally. The process may take several attempts. That's normal. The first version may be awkward. The second may feel better. The third may reveal something you didn't even realize you wanted to say. Keep going. Eventually, something changes. You stop "giving a speech." You start having a conversation. And that's when people lean in. And you’ll have more fun. That's when your expertise becomes accessible. That's when your message becomes memorable. So, should you write your presentation first?
- Write only short ideas about your points
- Speak extemporaneously about those points to discover your true voice
- Write down when you said a “winner.”
That is where authentic, powerful communication happens.
