How to stop saying “um”

Filler words are a habit, not a flaw. A few go unnoticed; many make you sound unsure. Here is why they happen and how to cut them.

Key takeaways

  • Fillers hold the floor while you plan the next words.
  • A short pause sounds more confident than “um.”
  • Learn your own fillers: “like,” “so,” “you know,” “basically.”
  • Measure your rate against yourself, talk after talk.

Why fillers happen

Speaking and planning happen at the same time. When the next words aren’t ready, a filler keeps the floor: it tells listeners you aren’t finished. That is why fillers cluster at the start of sentences, before a new point, and after a hard question.

Not every filler is a problem

In conversation, a few fillers sound natural, and removing every one can make you sound rehearsed. They matter when they pile up: in a presentation, an interview or a pitch, where every word is heard and many fillers read as doubt.

Find your own fillers

Most people have two or three favorites, and rarely the ones they expect. “So” at the start of every answer, “like” in the middle of sentences, “right?” at the end. Record yourself in a real conversation, not a rehearsal, and listen for the words you could drop without changing the meaning.

Replace the filler with a pause

The pause is what the filler was hiding. A second of silence feels long to the speaker and normal to the listener. Practice ending each sentence with a full stop and a breath before the next one.

Know where you’re going

Fillers fall when the next step is clear. Announce the shape of the answer, “Two reasons,” and you always know what comes next. Before a talk, know your first sentence and your last one by heart.

Practice where it’s cheap

Work on one filler at a time, in conversations that don’t matter much: ordering coffee, a call with a friend, a team stand-up. Habits change in low-stakes moments and then show up when it counts.

Track it over time

A single recording tells you where you are; a series tells you whether you’re improving. Compare yourself with your own last talk, never with a stranger’s average.

Questions people ask.

Are filler words bad?

Not in small numbers: they are part of natural speech. They become a problem when there are many, especially in talks and interviews.

Why do I say “like” so much?

It often marks an example or buys time to find the next word. Notice when you say it, and try a pause instead.

Is “so” at the start of an answer a filler?

When it carries no meaning, yes. Start with the answer itself.

Can I practice alone?

Yes. Explain something out loud for two minutes, record it, count the fillers, and try again.
