To stop saying "um," don't try to delete it. Replace it. Every time you feel an "um" coming, close your mouth and take a silent beat instead, then say the next phrase. Pair that with knowing your point before you start talking, and the fillers lose the job they were doing.

That's the short version. The longer version matters, because the most common advice ("just stop saying um") tends to make things worse. If you've ever tried to police every filler word in real time, you probably noticed you started sounding stiff, or you lost your train of thought. There's a reason for that, and once you see it, the fix gets much simpler.

This page walks through why fillers happen, how to measure yours, a short drill to replace them, and how to carry the habit into real conversations. If you want the bigger picture of how your voice and words come across, start with how to speak with confidence.

Why filler words aren't the real problem

"Um," "uh," "like" and "you know" aren't random. They show up at a specific moment: when your mouth is ready to keep going but your next thought isn't ready yet. The filler holds the floor. It says, "I'm still talking, don't jump in," while your brain looks for the next word or decides where the sentence is going.

So the need underneath the filler is real. You need a moment to think. Everyone does. The habit is in how you spend that moment. Somewhere along the way most of us picked up the idea that silence in the middle of speaking is dangerous, so we fill the gap with sound.

That's why suppression alone backfires. If you spend a conversation listening for your own "ums," you've added a second job on top of the first one. Now you're trying to say something clear and monitor yourself at the same time. The monitoring uses up attention you needed for the thinking, so your sentences get simpler, your delivery gets flatter, and you can still end up hesitating. You traded one problem for another.

The better question isn't "How do I stop the sound?" It's "What do I do with the gap instead?" The answer is a pause, and a bit of planning so there are fewer gaps to begin with.

Count them first: one recorded minute

Before you change anything, get an honest baseline. You can't hear your own fillers well while you're talking, because you're tracking what you mean, not what comes out.

1. Pick a topic you know well. Your job, a project, a hobby, a recent trip. Don't write anything down.
2. Record yourself talking about it for one minute. Your phone's voice memo app is enough.
3. Play it back and tally every filler. Make a mark for each "um," "uh," "like," "you know," "so" at the start of a sentence, and any other sound you use to hold the floor.
4. Note where they land. Are they at the start of your answer? Between ideas? Right before a hard word or a number?

Keep the number somewhere. You'll record the same topic again after a week of practice, and comparing the two tells you far more than how it felt in the moment. Most people find their fillers cluster in a few predictable spots, and that pattern tells you where to focus.

The 10-second clarity drill: replace "um" with a silent beat

This is the core skill. You're giving your brain a different tool to reach for in the exact moment it used to reach for "um."

The daily version (about ten seconds):

1. Pick one ordinary question. "What's on my calendar today?" "What did I have for breakfast?" "What's the weather doing?"
2. Form the whole answer silently first. Hear the full sentence in your head, start to finish, before you say a word.
3. Say it out loud, straight through. Don't edit mid-sentence. Just deliver the sentence you built.
4. Notice how it sounded. A sentence you finished in your head before speaking rarely needs a filler, because there's no gap left to fill.

Do that once a day, before your first call or meeting. The question doesn't matter. What you're practicing is the order: think the sentence, then say it.

The recorded version (a few minutes, a few times a week): Go back to your one-minute topic and record it again. This time, every time you feel an "um" coming, stop talking for a beat instead. Close your mouth, breathe if you need to, then continue with the next phrase.

It will feel strange. The silence will seem long while you're holding it. Then you'll play it back and hear something different: the pauses sound much shorter than they felt, and many of them land right where a pause belongs anyway, at the end of a thought.

A few rules make the pause work:

• Pause at the end of a phrase, not in the middle. "We need to make a decision. (pause)" sounds settled. "We need to (pause) make a decision" sounds unsure.
• Stay still. If you fidget or look away during the pause, it reads as discomfort. Keep your eyes and body quiet and let the silence do its job.
• Don't overdo it. Once pauses start working, it's tempting to put one before every sentence. That turns into a performance. Use them where a comma or a period would go.

If you want to go deeper on the pause itself, including how long to hold one in different moments, I cover that in how to use pauses when speaking.

Fillers are often one piece of a bigger pattern in how you come across, and it's hard to spot your own pattern from the inside. My short Communication Blind-Spot Quiz takes about two minutes and points out the habit worth working on first.

Know your first and last sentence: fillers live in transitions

Look at where your tally marks landed. For a lot of people, the fillers aren't spread evenly. They pile up in three places: right at the start of an answer, in the handoff between one idea and the next, and at the end, when you're not sure how to stop.

Each of those is a moment where you don't yet know your next sentence. So plan those sentences.

• Your first sentence. Before you speak, finish this line in your head: "The one thing I want them to understand is ___." Say that first. Once you know where you're headed, you're not building the route while you walk it.
• Your transitions. Use short, plain markers instead of "um, so, anyway." "Here's the second reason." "What that means is this." "The next step is." They give your brain a beat to think and tell the listener you've moved on.
• Your last sentence. Decide how you'll finish: restate the point, name the next step, or hand it back with a question. Then stop, and let the silence sit. Trailing "so, yeah, um" is usually just the search for an ending.

Here's the difference in an everyday answer. Without a plan: "Um, yeah, so I think, like, the main issue is probably that we don't really have, you know, enough visibility into where things are, so, um..." With a plan: "The main issue is visibility. We can't see where things are stuck. I'd start by fixing that."

Same idea. The second version had a first sentence and a last sentence ready, so there was nothing to fill. This is the same mechanic that stops rambling, and I go through it step by step in how to stop rambling when you speak.

Practice in low-stakes conversations

The drill builds the skill. Ordinary conversations make it automatic. Don't wait for a big presentation to try pausing for the first time, because that's exactly when your old habit is strongest.

• Pick one low-stakes moment a day. Ordering coffee, a quick question from a coworker, a phone call with a friend. Use the silent beat once or twice on purpose.
• Work on one spot at a time. If most of your fillers come at the start of answers, spend a week only on that: pause, then give your first sentence. Leave the rest alone.
• Rehearse the important things out loud. Before a meeting or a talk, say your opening and closing out loud a few times, with the pauses in. Rehearsing in your head doesn't train your mouth.
• Re-record after a week. Same topic, same minute. Compare the tally with your baseline.

Expect progress, not perfection. You've had this habit for a long time, and a few fillers will keep showing up, especially when you're tired or caught off guard. That's fine. The goal is that your pauses start doing the work your fillers used to do. Once that happens, people stop noticing how you're talking and start paying attention to what you're saying.

And if fillers aren't your main issue, but your voice tends to stay on one note, that's a separate fix. I cover it in how to stop sounding monotone.

FAQ

Are a few "ums" OK?

Yes. Nobody speaks with zero fillers, and an occasional "um" in conversation sounds normal. Fillers become a problem when they pile up enough that people start hearing them instead of your point, or when they make you sound unsure about something you actually know. Aim for fewer, not none.

What about "like," "you know" and "so"?

They're the same habit wearing different clothes. Each one holds the floor while you think. The fix is the same too: notice where they show up, put a silent beat there instead, and plan your first sentence so you don't start with "So, um." Some people find that "like" drops off on its own once they slow down a little.

How do I stop saying um when presenting?

Rehearse out loud, not just in your head, and plan the moments where fillers usually sneak in: your opening line, the move from one section to the next, and your closing line. Say those exact sentences a few times before you present. During the talk, if you lose your place, pause and look at your notes. A silent moment reads as thinking. A string of "ums" reads as lost.

Why do I say um so much?

Usually because you start speaking before your next thought is ready, and silence feels uncomfortable, so you fill it. It often gets worse when you're nervous, tired, or answering something you didn't expect. It's a habit, not a sign that you don't know your material, and habits can be replaced with practice.

How long does it take to stop using filler words?

It varies by person and by how often you practice. Most people notice a difference when they listen to a recording after a week or two of daily drills, even if it doesn't feel different yet while they're talking. Keep recording and comparing, because the playback is a better judge than how it feels in the moment.
