You know the feeling. You're mid-sentence in a meeting, your brain reaches for the next word, and out slips another "um." Then a "like." Then an "uh, you know." By the time you finish, you're wondering whether anyone heard your actual point or just counted your fillers. If you've been searching for how to stop saying um, here's the good news: filler words are a habit, not a personality trait, and habits can be retrained.
Even better, this is one of the fastest speaking skills to improve. Unlike stage presence or storytelling, which take months to develop, most people can cut their filler words dramatically in a few weeks of focused practice. You don't need a speech therapist or a Toastmasters membership to start. You need awareness, a handful of specific techniques, and reps.
This guide covers why fillers happen in the first place, why they cost you more credibility than you probably realize, and nine practical techniques you can start using in your very next conversation.
Why We Say "Um" in the First Place
Filler words aren't random. They show up for two predictable reasons, and knowing which one drives your fillers tells you which fix to reach for.
Reason one: cognitive load. Speaking is a juggling act. Your brain is simultaneously planning what to say next, choosing words, monitoring your listener's reaction, and physically producing sound. When the planning part falls behind the talking part, your mouth keeps moving anyway, and "um" is what comes out. It's a verbal loading spinner. That's why fillers spike when you're explaining something complex, answering an unexpected question, or speaking about a topic you haven't fully organized in your head.
Reason two: pause aversion. Most of us are deeply uncomfortable with silence while we hold the floor. A pause feels like dead air, an invitation for someone to interrupt, or a signal that we've lost our train of thought. So we plug the gap with sound. "Um," "uh," "like," "so," and "you know" are all placeholders that say I'm not done yet without saying anything at all.
Here's the twist: the pause you're avoiding is almost always better than the filler you're replacing it with. Listeners experience a confident pause as thoughtfulness. They experience "um" as hesitation.
Why Filler Words Hurt More Than You Think
A few "ums" won't sink a presentation. But past a certain density, fillers actively work against you in three ways.
They chip away at credibility. Filler words are among the first things listeners notice, even when they couldn't tell you why a speaker seemed unsure of themselves. Fillers read as hedging. When every third sentence starts with "so, um, like," your audience starts to wonder whether you know your material, even if you know it cold.
They wreck your pacing. Fillers don't just fill pauses; they destroy them. Pauses are how skilled speakers create emphasis, let key points land, and give listeners time to process. When every gap gets stuffed with "uh," your speech becomes a flat, unbroken stream with no rhythm and no highlights.
They bury your message. Attention is finite. Every filler is noise competing with your signal. The more your audience filters out, the more of your actual content gets filtered out with it.
The goal isn't zero fillers, by the way. Natural conversation includes some, and chasing perfection makes speakers stiff and self-conscious. The goal is to get fillers rare enough that they disappear into the background instead of becoming the thing people remember.
9 Techniques to Stop Saying "Um"
Work through these roughly in order. The first three attack pause aversion, the middle group attacks cognitive load, and the last few build the practice loop that makes the change stick.
1. Embrace the pause
This is the single highest-leverage fix. When you feel an "um" coming, close your mouth and let the silence sit. It will feel eternal to you and completely normal to everyone else; speakers consistently overestimate how long their pauses last. Practice it deliberately: in your next low-stakes conversation, pick one moment to pause for a full second before answering. Notice that nobody flinched. Silence is not a gap in your speech. It is your speech.
2. Slow your speaking rate
Fillers multiply when your mouth outruns your brain. Dropping your pace even slightly gives your planning process time to catch up, which means fewer moments where you're vamping with "uh" while searching for the next word. You don't need to speak in slow motion. Aim for the pace you'd use explaining something important to one person, not the pace you use when you're nervous and trying to get it over with.
3. Chunk your sentences
Long, winding sentences are filler factories, because you're building the ending while still delivering the middle. Instead, speak in short, complete thoughts. Say one idea. Stop. Say the next idea. The period at the end of each chunk gives you a natural landing spot to breathe and plan, exactly where an "um" would otherwise sneak in. As a bonus, chunked speech sounds more decisive and is easier to follow.
4. Record yourself and count
You cannot fix what you can't hear, and almost nobody hears their own fillers in real time. Record two minutes of yourself answering a simple question, then play it back and tally every "um," "uh," "like," and "you know." The first listen is usually humbling. That's the point. Awareness alone reduces fillers, because your brain starts flagging them mid-sentence instead of after the fact. Make this a weekly habit and track the count over time.
5. Know your trigger words and moments
Everyone has a filler signature. Some people "um" at the start of sentences, some "like" in the middle, some deploy "you know" as a question-ender. And most people have trigger situations: being put on the spot, transitioning between topics, or answering questions they didn't prepare for. Review a recording and find your pattern. Once you know that your fillers cluster at sentence openers, for example, you can build the specific habit of starting sentences with a breath instead.
6. Prepare your transitions
In prepared talks, fillers concentrate at the seams: the moments between one point and the next, where you're deciding what comes next in real time. Remove the decision. Script and memorize your transitions word for word, even if you improvise everything else. Simple lines like "That covers the problem. Here's our solution." are cheap insurance against the classic "so, um, yeah, moving on" stumble.
7. Breathe from the diaphragm
Shallow chest breathing, the kind nerves produce, leaves you short of air mid-sentence, and running out of breath is a classic filler trigger. Practice breathing low into your belly: inhale so your stomach expands while your shoulders stay still. Before speaking, take one slow diaphragmatic breath. During speech, use your sentence breaks (see technique 3) to top up. A supported breath gives you a steadier voice and fewer desperate "uhs" while you gasp for the next phrase. If nerves are the deeper issue, it's worth reading our guide on overcoming speaking anxiety, because anxious speakers filler more no matter how good their technique is.
8. Practice with feedback, not just repetition
Rehearsing without feedback mostly reinforces whatever you already do, fillers included. You need a loop: speak, measure, adjust, repeat. That can be a friend who raises a finger every time you say "um," a recording you review honestly, or a tool that counts for you. The measurement matters more than the method. When you can see your filler rate going down week over week, the habit change accelerates, because progress you can see is progress you'll keep chasing.
9. Rehearse out loud, every day
Silent rehearsal doesn't train the muscles that produce fillers. Speaking does. Five minutes a day of talking out loud, whether that's rehearsing a real presentation, summarizing an article you just read, or narrating your plan for the day, builds the fluency that makes fillers unnecessary. Daily beats marathon: a short session every day rewires the habit faster than one long session a week. You don't need an audience or a stage for any of this; here's how to practice public speaking at home with nothing but your phone and a few spare minutes.
How Long Does It Take to Stop Saying Um?
Faster than you'd expect, if you practice deliberately. Here's a realistic timeline:
- Week 1: Awareness kicks in. You start hearing your own fillers mid-sentence, which feels worse but is actually the first sign of progress.
- Weeks 2–3: With daily out-loud practice and regular feedback, most people see a meaningful drop in prepared speech, the kind you've rehearsed.
- Weeks 4–8: The improvement spreads to spontaneous speech: meetings, Q&A, casual conversation. This takes longer because there's no script to lean on.
- Ongoing: Expect regression under pressure. High-stakes moments push filler rates back up temporarily. That's normal, not failure. The baseline you've built means "bad" days still beat your old good days.
The pattern to expect is a steep early drop followed by slower gains, which is why tracking matters. Without numbers, the slow phase feels like a plateau and people quit. With numbers, you can see the line still trending down.
If you want that tracking handled for you, SpeakUp is an AI speaking coach that listens to your practice sessions and counts your filler words per minute automatically, alongside your pace and clarity, so every rehearsal shows you exactly where you stand and whether this week beat last week. The free plan includes five practice sessions a month, which is enough to run the weekly recording habit from technique 4 without spending anything.
FAQ
Why do I say um so much?
Usually one of two reasons: your brain is planning your next words slower than your mouth is producing them (cognitive load), or you're uncomfortable with silence and filling every pause with sound (pause aversion). Nerves amplify both, which is why fillers spike in interviews and presentations. The fix depends on the cause: slow down and chunk your sentences for the first, practice deliberate pausing for the second.
Is it bad to say um in a presentation?
A few fillers are completely normal and most audiences won't consciously notice them. The problem is density: when fillers show up in nearly every sentence, they start to read as uncertainty and pull attention away from your message. Aim to make fillers rare rather than eliminating them entirely, since obsessing over perfection tends to make speakers stiff.
How many filler words per minute is normal?
Filler rates vary widely by speaker and situation, and conversational speech naturally contains more than prepared remarks. A useful practical benchmark: if listeners can notice and count your fillers, you have too many; if they'd struggle to recall any, you're fine. Rather than chasing a universal number, measure your own baseline with a recording, then work to bring it down week over week.
Does slowing down really reduce filler words?
Yes, and it's one of the most reliable fixes. Fillers appear when speech production outpaces speech planning, so reducing your rate closes that gap and gives your brain time to select the next words. Slowing down also makes deliberate pauses feel more natural, which removes the urge to fill silence with sound.
