Filler words like um, uh, and like multiply under pressure. A few are human and fine; a constant stream undermines your authority and distracts the listener. The good news is that fillers are a habit, and habits can be retrained.

Understand why they happen Fillers fill silence. Your brain hits a tiny gap while reaching for the next word, and rather than allow a pause, it blurts a sound to hold the floor. The fix is not to talk faster; it is to get comfortable with silence.

Replace the um with a pause This is the single most effective technique. When you feel an um coming, simply stop and say nothing. A one-second pause feels like an eternity to you and like confident composure to your audience. Pauses also give listeners time to absorb what you just said.

Slow down overall Most filler words come from rushing. When you race ahead of your own thoughts, you create the gaps that ums rush in to fill. Deliberately slowing your pace gives your brain time to find words without a verbal placeholder.

Practice with feedback - Record yourself speaking for two minutes and count your fillers. Awareness alone cuts the count. - Ask a friend to gently raise a hand each time you say um in conversation. It is uncomfortable and remarkably effective. - Rehearse your key transitions, where fillers cluster most.

Do not over-correct The goal is natural, not robotic. A speaker with zero pauses and zero fillers sounds rehearsed and stiff. A few human moments are fine. Aim to replace the nervous, repetitive fillers with confident, deliberate silence, and your whole delivery will sound more credible.
