How to stop saying "um" when you present
Why filler words show up when you speak, and five practical drills that cut "um", "uh" and "like" before your next presentation.
Almost everyone says "um". It is not a sign that you are unprepared or nervous; it is how speech works. Your mouth is ready to keep going while your brain is still choosing the next words, so it fills the gap with a sound that says "I'm not finished yet".
In conversation nobody notices. On stage it is different. The audience has nothing else to listen to, so a handful of fillers per minute starts to sound like hesitation, and hesitation sounds like doubt about your own point.
The good news: you do not need to remove every filler. You need to replace most of them with something better, and that something is silence.
Why fillers appear
Fillers cluster in three places:
- At transitions. The end of one idea and the start of the next is where you are searching hardest for words. "So, um, the next thing…"
- When you are not sure what comes next. If you have not rehearsed the order of your points out loud, you improvise the order live, and improvising produces fillers.
- When you are afraid of silence. A two-second pause feels endless to the speaker. To the audience it feels like emphasis.
Notice that two of the three are about preparation, not personality. That is why rehearsing out loud changes filler words more than any trick does.
1. Find out how many you actually say
Most people underestimate their fillers, because they don't hear them while speaking. Record one run of your talk and listen back, or rehearse with a tool that counts them for you. Write down two numbers: fillers per minute, and where they bunch up. Usually it is the same few transitions every time.
You now have a baseline, and a short list of the exact moments to work on.
2. Rehearse your transitions, not just your slides
People practice the content of each slide and then wing the jumps between them. Do the opposite for a while: say only the last sentence of one section and the first sentence of the next, out loud, until the bridge comes out without searching.
A useful pattern is to end each section with a one-line summary and start the next with a question: "So that's why the pilot worked. What does it cost to roll out?" The question gives your mouth something to say while your mind moves on.
3. Replace the filler with a pause
When you feel an "um" coming, close your mouth and pause instead. It is uncomfortable the first few times, so practice it on purpose: rehearse a section and insist on a full breath at every full stop.
Pauses do three jobs at once. They give you time to think, they give the audience time to absorb the last point, and they make you sound deliberate. Speakers who pause well are usually described as calm and confident, even when they don't feel it.
4. Slow down a little
Fillers and speed go together. When you rush, you run out of prepared words faster and fill the gaps. A comfortable pace for most presentations is roughly 120 to 165 words per minute. If you are above that, you are probably also saying "um" more than you would like.
Pick one slide and deliver it at a deliberately slow pace, with pauses. Then do the next slide at your normal speed and compare how it felt.
5. Know your first and last sentences by heart
The opening and the close are where nerves peak. Memorize the first two sentences and the final two, word for word. Not the whole talk, which would make you sound recited, just the edges. A clean start removes the burst of fillers that usually hits in the first minute, and a clean ending stops the trailing "so, um, yeah, that's it".
How to practice this week
- Do one full run and measure your fillers per minute.
- Drill your three worst transitions out loud, five times each.
- Do a second full run with one rule: pause instead of filling.
- Measure again and compare.
Most people see a clear drop between the first and the third run, simply because the order of their ideas stops being improvised.
RehearseWise does the measuring for you: it listens while you rehearse to your webcam, counts filler words, tracks your pace slide by slide and shows the exact moments to replay, so you can see the change from one run to the next.
