Using AI to Write a Speech: What It Can't Do for You

Using AI to Write a Speech: What It Gets Right and What It Can't Find

AI is great at organizing what you give it. Here's the part it can't do for you.

October 27, 2026

You open ChatGPT and type something like "write me a 30 minute talk on leadership for a sales conference." Twenty seconds later you've got a speech. Clean intro, three points, a quote from somebody famous, a nice close. It reads fine.

Then you read it out loud. And it could be anybody's. Swap your name for the next speaker's and nobody in the room would notice.

That's not because you used AI wrong. It's because you asked it to do the one part of a speech it can't do. AI can do a lot of the work of writing a speech. It just can't do the part that gets you remembered, booked and paid.

The short answer: Using AI to write a speech works for the mechanical parts: putting your notes in order, tightening a draft that runs long, fitting it to your time slot and poking holes in your argument. It doesn't work for the part that matters most, which is finding your point of view and the stories only you can tell. Bring those first, verify every fact it gives you, and let it organize.

Can you use AI to write a speech?

Yes, for parts of it. Not for the whole thing.

Even Toastmasters, an organization built around people writing and giving their own speeches, landed there. Its April 2026 magazine ran a piece on the dos and don'ts of using AI in speechwriting. Use it for research, brainstorming, organizing and finding blind spots. Don't have it write the speech, because your original insight and experience are what the audience came for. The same piece warns that AI can invent things outright. When the writer asked ChatGPT for quotes from a survey, the quotes it gave back didn't match the originals.

So the real question isn't whether to use it. It's which parts you hand over and which parts you keep.

What is AI good at when you're writing a speech?

AI is good at working with material you already have. Give it something real and it'll make it cleaner, faster.

Putting your notes in order. If you've got a pile of stories, points and half sentences, it can find a sequence that makes sense.
Cutting. Your draft runs 52 minutes and you've got 40. It's good at finding the repeats and the throat clearing.
Playing the skeptic. It can push back on your argument the way a doubtful person in row three would, which helps you find the soft spots before the room does.
Catching jargon. After 15 years in a field, you stop hearing your own acronyms. It hasn't.

Every one of those starts with something you gave it.

What can't AI do for your speech?

It can't find your insight. It can't know your stories. And it can't notice what you left out.

In my keynote work I call the generic stuff leaves. Leadership. Communication. Resilience. Customer service. They sound like talks and they're everywhere, which is exactly what AI produces when you ask for a speech on a topic. It predicts the most likely version of that talk, and the most likely version is the one everybody else already gave. A talk that gets booked runs on a root, something you only know because you've lived inside your work for years. (The full Leaf to Root idea lives in How to Write a Keynote Speech, so I won't re teach it here.)

For example, picture a property manager who's run apartment buildings for 15 years. Ask AI for a talk on tenant relations and you get "five keys to better communication with residents." Totally fine. Totally forgettable. Her root might be something she's watched play out hundreds of times: most residents don't move out over the first broken thing, they move out over how long the second one took. That's a hypothetical, but feel the difference. One is a topic. The other is a point somebody could argue with, and it came from years of her work, not from a prediction.

AI didn't have that sentence. She did. And she probably wouldn't have typed it in, because to her it's just how buildings work.

AI is great at organizing what you give it. It's terrible at noticing what you left out.

Which parts of a speech should you hand to AI?

Hand it the parts where your material already exists. Keep the parts where the material has to come out of you.

On that last row: an opening has about 15 seconds to earn the room, and generic loses it. I get into why in How to Open a Keynote Speech.

Can audiences tell when a speech was written by AI?

Often they think they can, and that's enough to cost you.

In Animoto's 2026 State of Video Report, a vendor survey of 450+ US consumers and marketers, nearly 83% of consumers said they'd watched a video they suspected was AI generated, and 36% said an AI generated video would lower their perception of the brand. That's video, not speeches. But a speech that sounds like the average of every speech gives off the same feeling. People can't always say what's off. They just stop leaning in.

Event planners feel it too. A 2026 planner guide from Speakers.com put it plainly: "a canned presentation is the fastest way to lose an audience." A talk generated from a topic is about as canned as it gets.

Should you tell people you used AI to write your speech?

The research says disclosure has a cost, and hiding it has a bigger one.

Researchers at the University of Arizona ran 13 experiments with more than 5,000 participants and found that people who said they'd used AI on their work were trusted less, even by evaluators who liked technology. The researchers also found that AI use that's hidden and later discovered may do the most damage of all.

I read that and think the disclosure question is a symptom. If AI helped you put your own thinking in order, that's an editor, and nobody apologizes for having an editor. If AI supplied the thinking, the problem isn't whether you mention it. The problem is that the talk isn't yours, and the room was always going to feel that.

Why does an AI written speech sound like everybody else's?

Because it was built from everybody else's.

The good stuff in a talk usually lives in a place you don't think to look. A construction executive I worked with told me, "I think I have something. I don't know what it is." He'd been in construction for 20+ years. What came out wasn't new knowledge. He didn't learn one new thing. It was something he'd been saying for years and had never actually heard himself say. He's speaking monthly now and hosting his own paid virtual events.

No chatbot would have found that, because he never would have typed it in. It took somebody asking about the specific thing he said, then asking again. That's the part of writing a speech nobody can automate yet: the follow up question.

So if your AI drafts keep coming out like everybody else's, you're not bad at this. You're feeding it leaves because the roots don't feel special to you. You've been doing what you do so long it feels like a regular Tuesday.

I compared the options side by side (ChatGPT alone, a speaking course, 1:1 coaching) in this breakdown of what each one is actually good for. Short version: if you already know your point and your stories, ChatGPT will get you a long way. If you don't, no tool fixes that by organizing harder.

Let AI organize. Get the digging done first.

That digging is what Build Your Keynote does. It's a speaking accelerator built on my process and hundreds of hours of 1:1 coaching. Eight sections, asked one at a time. You answer in your own words, and when an answer is thin it asks about the specific thing you said instead of moving you along, the way I would sitting across from you. Every word starts as something you said. You walk out with your core insights, a program description and a keynote outline. Yes, AI is part of how it works. I'm not hiding that. The difference is it goes looking for what you left out before it organizes anything.

To be clear, it's not a course. There are no videos, and it only works if you actually answer the questions. If you want something to write a talk for you while you watch, this isn't it. If you've got years of work and a feeling there's something in there, start with section one. It's free, no card.

FAQ

Can AI write a speech for me?

It can write a speech, but it'll be a generic one. AI predicts the most likely version of a talk on your topic, which is the version everybody else already gave. It does much better organizing and tightening a speech built from your own point of view and stories.

Is it okay to use ChatGPT to help write a speech?

Yes. Use it to put your notes in order, cut a draft to time, catch jargon and raise objections. Don't let it supply your core message or your stories, and check every fact, stat and quote it gives you.

Can people tell if a speech was written by AI?

Often they suspect it. In Animoto's 2026 vendor survey, nearly 83% of consumers said they'd watched a video they suspected was AI generated, and 36% said AI video would lower their view of a brand. Generic, interchangeable lines are usually what gives it away.

Should I disclose that I used AI to write my speech?

University of Arizona research across 13 experiments found people who disclose AI use are trusted less, and hidden use that's discovered may hurt more. The stronger move is making sure the ideas and stories are yours, so AI only played editor.

What's the best way to use AI for a keynote speech?

Use it after you know what you believe and which stories prove it. Then let it organize, tighten and stress test. If you don't know your point yet, that's the work to do first, and it's work AI can't do for you.
