You watched yourself back — a meeting recording, a voice note, a video you almost posted — and you counted. Nine "likes" in thirty seconds. Four "ums" before you finished the first sentence. A "you know" you'd swear you never say. And you thought: I sound like I don't know what I'm talking about.
I've counted my own. It's a special kind of awful.
Here's the good news, and it's bigger than it sounds. You don't say "um" because you're nervous or slow or unprepared. You say it for one specific, fixable reason. Fix that and the fillers fall away on their own — no white-knuckling required.
Quick answer
You say "um" when your mouth starts a sentence your brain hasn't finished. The fix isn't suppressing the sound — it's getting comfortable with a one-second pause instead, so you can think without filling the silence. Don't aim for zero; that backfires. Record yourself, count your fillers, and watch the number drop.
Why you actually say "um"
Every guide tells you to stop. Almost none tell you why it happens, which is exactly why "just stop" never works. You can't will away a reflex you don't understand.
Here's the mechanism. A filler is the sound your mouth makes when it has committed to a sentence your brain hasn't written yet. You opened your mouth, sound is the contract, and now there's a gap where the next word should be. "Um" fills it. That's not stupidity. It's a timing mismatch — your speaking ran ahead of your thinking.
Now notice when it spikes. Reading from a script? Barely any ums. Someone asks you a question you didn't see coming? Suddenly you're "um"-ing every clause. That's the tell. You fill the most when you haven't decided what you actually think yet. The um isn't really a speech flaw. Half the time it's a thinking gap wearing a costume.
Once you see it that way, the job stops being "suppress the sound" and becomes "stop outrunning your own brain."
Stop trying to hit zero
Before the how, kill the goal that sabotages most people: zero fillers.
A speech scrubbed of every "um" doesn't sound polished. It sounds like a hostage video. One filler in a paragraph's worth of talking is invisible — nobody notices, and real speakers do it constantly. The problem was never the occasional "uh." It's the one every sentence or two, the "like" four times in a breath, the "you know" you bolt onto everything.
And chasing zero actively backfires. The harder you police each word, the more of your attention goes to monitoring your mouth instead of building your point — which leaves less brain for the sentence, which produces more fillers. You can talk yourself into a stutter.
So the target isn't "none." It's "not distracting." Much easier, and you'll get there faster.
One more piece of good news: you don't have a hundred fillers. You have two or three. Maybe it's "um" and "so." Maybe "like" and "you know." Maybe you open every sentence with "all right, so." Find your two or three — ask a friend, or better, hear them on a recording — and those are the only ones you have to fight.
The one swap that works
There's exactly one move underneath all of this: trade the filler for a pause.
Same gap, different filling. Instead of "um," nothing — a beat of silence while your brain catches up. A pause sounds better than a filler every single time. It slows your pace, it makes the next thing land, and it reads as thoughtful, which is the precise opposite of what the "um" was broadcasting.
The catch is that silence feels enormous from the inside. One coach described practicing pauses that felt like five or six seconds to him; on the video, they were two, and they sounded great. Your internal clock is lying to you. The pause you're scared of is shorter and better than you think.
Three things turn the pause from theory into something you can actually do:
- Close your mouth between sentences. Literally. Don't reopen it until you know the next sentence. An open mouth with no plan is where "um" lives. (Bonus: it makes you breathe through your nose, which steadies your voice.)
- Decide the sentence before you start it. Most fillers happen because you began talking and hoped the end would show up. Take the beat first, find the sentence, then say it.
- Speak on the exhale. Choppy, broken-up speech invites a filler into every gap. A sentence riding one smooth out-breath has fewer holes to plug.
Three drills worth stealing
These come from coaches who break this habit for a living. I've reframed them for practicing alone.
The period method. This one's almost magic, and it works in three stages. Practicing by yourself, every time you catch a filler, say the word "period" out loud in its place — right where the punctuation would go. Say it louder than normal so the fillers stand out. Stage one, you catch them after they slip out. Stage two, you feel one coming and say "period" before it escapes. Stage three, you say "period" only in your head — and now your listeners just hear a clean, confident pause. People break years-old habits with this in a few sessions.
The breath swap. Same idea, simpler: every time you'd reach for a filler, take a small breath instead. It gives your mouth a job that isn't "um," and to a listener an inhale just sounds like a natural pause. It's especially good at the start of a thought, where "all right, so…" likes to live.
The daily question. Set a recurring reminder. Once a day it pings you a question you didn't plan for, and you answer it out loud for sixty seconds, recorded, no notes. Spontaneous speaking is exactly where fillers breed, so it's exactly where you should train. Answer the same question two weeks apart and the difference is right there on tape.
That last drill is most of the reason this site exists — a random topic, a timer, talk. It's the daily-question habit without you having to invent the questions.
The step everyone quits: count it
Here's the part every guide includes and almost nobody does. Measure it.
One coach flat-out admits that most people skip the monitoring step because it takes time — record, re-listen, tally on paper, do it again next week. He's right. It's tedious, and tedious things don't survive a busy week.
But it's also the part that actually works. You can't improve a number you never look at. "I think I'm getting better" is not data. "Eleven fillers a minute last week, six this week" is.
So take the tedium out. When you practice a topic and record it, the built-in coach counts your fillers for you — every "um," "like," "you know," "kind of" — and hands you a number per minute, automatically, every session. The monitoring step nobody sustains by hand becomes something you can't help seeing. Treat it like a game: beat last time. Watch the count drop two weeks running and you'll believe the progress in a way that "I feel smoother" never delivers.
The real fix is upstream
Strip all of this back and you land where we started. You fill silence when you haven't decided what you think yet. So the deepest cure for "um" isn't a speech trick at all. It's having something to say.
That's a muscle, trained the same boring way as everything else: reps. Speak on things you didn't prepare for, out loud, often, until forming a thought in real time stops feeling like an emergency. Do that and the pauses get shorter on their own, because now there's a finished sentence waiting on the other side of them.
The syllable-policing gets you from distracting to clean. The thinking practice gets you from clean to good.
Try it now
Stop reading. Generate a random topic, set a one-minute timer, and answer it out loud — recorded. Don't fight the ums this time. Just talk, then look at the filler count and remember the number. Tomorrow, beat it.
If you want the full solo routine around this, here's how to practice public speaking by yourself. And if the silence still scares you, pre-load a structure like PREP so you always know what sentence comes next.
