How to Stop Using Filler Words: 7 Techniques That Actually Work

Filler words are the sounds, words, and short phrases people add to speech that carry no real meaning but fill the silence while the brain searches for what to say next. "Um," "uh," "like," and "you know" are the most familiar examples, but the category also includes phrases such as "I mean," "basically," and "at the end of the day."

If you have ever wondered what are filler words in speech technically, linguists call them disfluencies: interruptions in the smooth flow of a sentence that do not add information for the listener. They differ from stutters or true speech disorders because they are a habit, not a physical impairment, which is exactly why they respond so well to deliberate practice.

Not every use of these words counts as a filler. Saying "I feel like this is a good idea" uses "like" correctly, as a comparison word. The same word becomes a filler only when it is inserted automatically, out of habit, and could be deleted without changing the meaning of the sentence. Learning how to stop using filler words starts with learning to notice that difference in your own speech, in real time, which is harder than it sounds since your brain edits out your own disfluencies as you speak.

The most common filler words fall into a small handful of patterns, and most speakers lean on just two or three of them without noticing.

At the top of nearly every list are "um" and "uh," the two vocalized pauses that fill space while the brain retrieves the next word. Close behind are crutch phrases like "like," "you know," and "I mean," which tend to show up at the start or end of a sentence rather than the middle.

A few other common filler words are easy to miss because they sound like ordinary words: "so," "basically," "actually," and "right" all function as fillers when they get repeated every few sentences without adding structure, such as opening every interview answer with "so." Qualifiers like "kind of," "sort of," and "just" round out the list, softening a statement more than most speakers intend.

Most people have a personal shortlist of two or three common filler words they rely on far more than the rest. Spotting yours is the real first step toward fixing the habit, and it is usually faster than expected once you start listening for it on purpose.

Filler words are not a sign of nervousness alone, and they are not a vocabulary problem. They happen because speaking in real time asks your brain to select words, build grammar, and coordinate your mouth simultaneously, all while you are also thinking about what to say. When that process hits even a half-second delay, a filler word steps in to hold your place in the sentence.

A few situations reliably increase filler word frequency: unfamiliar topics that demand more mental effort, evaluation pressure such as interviews or presentations, speaking in a second language, and unscripted speech in general, since there is no time to edit before you speak. Even confident, articulate speakers use more filler words when the stakes go up, because the extra cognitive load has to come from somewhere, and monitoring your own delivery is usually the first thing to slip.

Group size plays a role too. Speaking to one person face to face produces noticeably fewer filler words than presenting to a room, because a larger audience raises self-monitoring and self-consciousness at the same time it demands more working memory for content. Familiarity with the material cuts the other way: rehearsed material, even loosely rehearsed, reduces filler words because less of your attention is spent deciding what to say next.

This matters because it changes the fix. Filler words respond poorly to willpower alone. Telling yourself to "just stop saying um" rarely works under pressure, because the pressure is what caused the habit to surface in the first place. They respond much better to structural changes in how you pace, prepare, and practice your speech, which is exactly what the techniques below focus on.

These seven techniques are how to stop using filler words in a way that lasts, because they target the mechanics behind the habit rather than asking you to suppress it through willpower alone. Work through them roughly in order; each one makes the next easier.

"Um" deserves its own answer because it is usually the single most frequent filler word, and it has a specific trigger: it shows up almost exclusively at the exact moment you are retrieving a word or deciding what to say next.

The fastest way to handle this is knowing how to stop saying um at the exact trigger point rather than after the fact. Notice the half-second right before an "um" would normally appear, usually right after a question, or at a natural pause between ideas, and consciously insert silence there instead. It feels unnervingly long the first few times. It rarely sounds that way to the listener.

A second approach works well alongside the first: shorten your sentences. Long, unplanned sentences give your brain more chances to stall mid-thought, and each stall is a potential "um." Breaking a complex answer into two or three shorter sentences reduces the number of moments where your brain needs to buy time.

Most people who successfully stop saying um do it gradually, cutting frequency by half within a couple of weeks of deliberate practice rather than eliminating it overnight. That is a realistic and durable target, and it is also the point where most listeners stop noticing it at all.

There is no fixed timeline, but the pattern is consistent: filler words are a habit, not a permanent trait, and habits respond to repetition. Most people who practice deliberately notice a measurable drop within two to three weeks, and a durable change, one that holds up under pressure, within four to six weeks.

A few factors change the timeline. How long the habit has been in place matters: filler words you have used since childhood take longer to override than a habit that crept in during a stressful season at work. How often you practice matters more than how long each session runs; five focused minutes daily beats one long session a week. Whether you practice under realistic pressure matters too. Progress made in a quiet room does not automatically transfer to a live interview or a packed conference room; that gap closes only with practice that simulates the real stakes, not just quiet rehearsal.

Expect some regression along the way. It is common to make real progress in low-stakes conversations and then watch old habits reappear the moment stakes rise, such as the first few minutes of an actual interview. That is not a sign the technique failed; it is a sign the practice needs to happen closer to the real conditions, not further from them. Each time you push through a high-pressure moment with fewer filler words, the gap between practice and performance gets smaller.

The goal is not zero filler words. Even experienced speakers use them occasionally, and eliminating every single one can sound stiff or over-rehearsed. The realistic goal is cutting the frequency enough that listeners focus on what you are saying instead of how you are saying it.

Knowing how to stop using filler words is straightforward on paper. Doing it in a real interview, a live presentation, or a difficult conversation is where the habit actually gets tested, and that only changes with repetition under something close to real conditions.

SayNow AI gives you a space to rehearse specific speaking scenarios, from job interviews to sales pitches to public speaking, and get direct feedback on filler word frequency, pace, and clarity after every session, so you can watch your patterns shift instead of guessing whether you have improved.

Start this week: record yourself on one topic, note which common filler words show up most, and apply a single technique, replacing the filler with a pause, or slowing your pace. Small, specific changes compound faster than trying to fix everything at once.
