How to stop saying “um”: a practical guide to filler words

“Um,” “uh,” “like,” “so,” and “you know” are not signs of a weak mind. They are what your mouth does while your brain catches up. The instinct to fill silence is so strong that we paper over every gap with a sound. The fix is not to think faster — it is to get comfortable with the gap.

Why fillers happen

A filler word is a placeholder you say to keep the floor while you decide what comes next. Silence feels, to the speaker, much longer and more dangerous than it actually is to the audience. So you reach for a sound that signals “I’m not finished” — and a habit forms.

Replace the filler with the pause

You cannot delete a habit; you can only swap it for another. The replacement for “um” is a closed-mouth pause. To the audience, a two-second silence reads as confidence and emphasis. To you, it feels like an eternity — which is exactly why you have to rehearse it until the discomfort fades.

• When you feel an “um” coming, close your mouth instead.
• Let the pause land. Count one-two in your head if you must.
• Then continue. The audience heard emphasis, not a gap.

A good pause is a feature, not a failure. The goal is not zero silence — it is silence you chose instead of a sound you didn’t.

Count them, because you can’t feel them

Filler words are nearly invisible to the person saying them. The only reliable way to reduce them is to count them — per minute, per section — and watch the number fall as you practice the pause. A measured filler-word rate turns a vague worry into a concrete, trainable target.

Train it in short reps

Pick one minute of material. Say it aloud, deliberately pausing where you would normally fill. Check the count. Repeat. One focused minute, done daily, retrains the reflex faster than an hour of unfocused practice — because you are rehearsing the specific moment where the habit fires.
