Filler Words: Stop Saying Um (Mostly)
Most people set the wrong goal. They want zero ums. Native speakers say um, uh, and like every day. In casual talk, a few fillers are normal. The problem is not the sound itself. The problem is how often you use it and what it tells the listener. You do not need to be perfect. You need control.
A learner's um is often a retrieval delay. The brain has the idea but cannot find the English word fast enough. The mouth fills the wait with sound. That is not a character flaw. It is a timing problem. If your ums come mostly before words you cannot remember, the fix is chunks and automatic phrases. That is the work on speaking fluently. This page is only about the sound you make while the brain catches up.
There is one strange fact about spoken English. A one-second silent pause often sounds confident. A half-second um often sounds lost. Same delay, different impression. The um tells the listener you are searching. The silence tells the listener you are choosing. Silence costs no effort and makes you look more in control.
Try it once. Next time someone asks you a question, wait one full second before you answer. Breathe. Look at them. It feels long. It does not sound long to the other person. That second gives you a clean start.
The swap strategy
Do not fight the urge to say um. Redirect it. When you feel the mouth opening for a filler, pick a replacement. You have two good options.
First, silence. Close your mouth and let the pause exist. If you need more time, nod once or take a breath. This is the fastest fix. It works in short answers.
Second, English thinking phrases. These buy more time and they sound fluent while you think. Say them in full:
- Let me think.
- Good question.
- How do I put this?
- I haven't thought about that before.
- The thing is...
These phrases are not empty. They tell the listener you understood and you are forming an answer. Um tells the listener you are stuck. The phrase buys a full second or more. The um buys less than half a second. Use the phrase.
Be careful with well. Well is a native filler, but it can become your new um. One well per answer is enough. If every sentence starts with well, you have just moved the problem to a better-sounding word.
Not all fillers are equal
Um is weak because it carries no meaning. Uh is the same. Like is normal in casual speech, but it becomes a problem when it appears three times in one sentence: I was like, and she was like, and I like, you know, like... At that point the listener cannot follow the idea. You know and I mean can work if used once, but they are also fillers in many cases. The goal is not to remove them all. The goal is to know which one you reach for and to have a better option ready.
If your main filler is like, do the same swap. Replace the third like with silence. You do not need to remove the first two. That alone cleans up most of the noise.
Count before you fix
Most people cannot hear their own fillers. They guess five ums in two minutes. A recording often shows 20 or more. You need the real number before you change anything.
Take two minutes. Record a voice note on your phone. Do not plan. Answer one simple question, like what did you do yesterday. Then count every um, uh, like, and any native-language filler. The page record yourself speaking English has a simple routine for this. The first day is usually embarrassing. That is fine. The number is a starting point, not a verdict.
One-week protocol
Two minutes a day is enough. Filler habits are physical. You are retraining the mouth, not studying grammar.
| Days | Action | Goal |
|---|---|---|
| 1-2 | Record two minutes. Count every um, uh, like, and native filler. | Get your real baseline |
| 3-4 | Same two-minute answer. When you feel an um coming, stop. Close your mouth for one second. | Replace um with silence |
| 5-7 | Same two-minute answer. Use one thinking phrase instead of silence at least twice. | Replace silence with natural phrases |
Do not try to do this all day. You will forget and then feel bad. Two minutes of focused practice does more than three hours of half-attention.
Native-language fillers leak in first
If you speak Spanish, Ukrainian, Russian, or another first language, you probably have a filler from that language: eh, este, ну, em. These leak into English before you notice. They mark you instantly. An English listener may not know the word, but they hear that the pause sound is not English. That breaks the sentence more than a simple um.
Swap those first. A native filler in an English sentence is louder than a grammar mistake. It interrupts the rhythm exactly when you are already pausing. Replace eh or ну with silence. It is the smallest change with the largest effect on how fluent you sound.
What shadowing does to fillers
Shadowing is speaking along with a video, just behind the speaker, so your mouth copies the sound and stress. It is not a filler drill, but it removes the filler from the model you copy. Prepared video has almost no ums and uhs. When you shadow clean audio, you train a clean version of the sentence. The more clean reps, the less often your brain reaches for a filler in the middle of a known phrase. See what English shadowing is for the theory and variants.
In the English Shadowing app, you can paste any YouTube link or search for a video. The subtitles show every word, and the current word is highlighted as the video plays. You can tap a sentence to jump to it, loop one sentence, and slow the video to 0.75x or 0.5x. It works in the phone browser, nothing to install. The app gives you clean input to copy. It will not count your ums. That part is still on you.
