# How to stop saying "um" in interviews

You record a practice answer on your phone, play it back, and start counting. "Um, so, basically, my project was, like, um, a food delivery app?" Eleven filler words. Forty seconds. Your answer had the structural integrity of wet biscuit, and the worst part is you had no idea you were doing it — nobody ever does. The first time I heard my own interview recording, I sounded like a man being interrogated about a crime he didn't commit. If you want to know **how to stop saying "um" in interviews**, the good news is this is the most fixable speaking problem there is. It responds to a specific drill within days, not months. Here's the whole method.

## Why you say "um" so much when nervous

"Um" isn't a bad habit you picked up — it's a system message. Linguists who study disfluency (Michael Erard wrote an entire book on this, literally titled *Um…*) have shown fillers appear when your brain needs a moment to plan the next phrase but doesn't want to surrender the floor. In conversation, that's useful: silence invites interruption, so "um" holds your turn.

Interviews break the equation twice. First, nerves shrink your planning capacity, so you need *more* bridges per sentence. Second — and this is the part nobody tells you — the interviewer isn't trying to interrupt you. The floor is yours for the length of your answer. Every "um" is you defending against a theft nobody is attempting. Which means the fix isn't suppressing the sound; it's replacing it with what it was always covering for: a pause.

## Do filler words matter in an interview?

Honest answer: a few don't, a flood does. Normal fluent speech runs about two to three fillers per hundred words — interviewers are human, they say "um" too, and nobody's docking points for it. Toastmasters clubs literally assign an "Ah-Counter" role in every meeting because even practiced speakers produce them.

What costs you is density. When every clause leans on "um," "like," "you know," "basically," three bad things happen: your answer takes 30% longer to say the same thing, the interviewer's attention drifts to the tic instead of the content, and — the real damage — you *sound* uncertain about things you actually know cold. In a phone screen with no video, your voice is the entire signal; a filler-heavy answer and a wrong answer can sound surprisingly similar down a phone line.

## The pause protocol: what to say instead of "um"

The replacement for "um" is nothing. Literally nothing. A one-second silent pause does everything "um" was doing — buying planning time, holding your turn — while reading as composure instead of doubt. Newsreaders and senior executives aren't fluent because they think faster than you; they've just made peace with silence.

The protocol, step by step:

- **Catch the trigger.** The urge to say "um" arrives a half-second before the sound. That gap is where you act — the whole skill is noticing it.
- **Close your mouth.** Physically. "Um" cannot be pronounced with closed lips. This sounds absurd and works immediately.
- **Breathe through the pause.** One nasal breath ≈ one second ≈ exactly the planning time your brain wanted.
- **Land the next phrase, then stop again.** Speak in chunks of one idea, with micro-pauses between them, instead of one long rope of clauses tied together with fillers.
- **Slow down 10–15% overall.** Filler density rises with speed. The same nervous energy that makes your [voice shake in interviews](/blog/voice-shaking-during-interview) also makes you sprint — slowing down attacks both.

One warning from honesty: don't aim for zero. Speakers who over-police fillers start sounding robotic and lose the thread of their own answer. Target is *fewer and quieter*, not extinct.

## Drills that cut filler words in a week

Awareness is 80% of this fix, and awareness only comes from hearing yourself. Four drills, in order:

- **Day 1 — get a baseline.** Record a two-minute answer to "tell me about yourself." Count the fillers. Write the number down; this is the score you're beating.
- **Days 2–3 — the transcript highlight.** Transcribe a recorded answer (any notes app dictation works) and highlight every filler. Seeing "um, like, basically" in print builds the disgust that fuels the habit change.
- **Days 3–5 — chunk reading.** Read any paragraph aloud, inserting a deliberate full-second pause at every comma and full stop. This trains your mouth that silence is survivable. It will feel unbearably slow; on a recording it sounds authoritative.
- **Days 5–7 — pressured reps.** Answer real interview questions out loud, with follow-ups you didn't script, while applying the closed-mouth pause. This is the transfer step — fillers cut in calm practice come sprinting back under pressure unless you rehearse under pressure.

That last step is where most tools fall short, so let's compare honestly. **Voice memos** are free and fine for the baseline, but nothing pushes back. **Yoodli** and similar speech-coaching apps count your filler words automatically and chart pacing — genuinely useful telemetry — but they grade delivery, not whether your answer was actually good. **Toastmasters'** Ah-Counter gives you accountability once a week, for speeches rather than interviews. **ChatGPT** asks fine questions but in text, and typing has never produced an "um" in recorded history. [Greenroom](/) closes the loop: Ari, the AI interviewer, runs the interview by voice, asks the unscripted follow-ups that spike your filler count, and the feedback covers both the delivery *and* the substance — because a beautifully paused answer that says nothing still loses. It's the same principle as [thinking out loud in interviews](/blog/how-to-think-out-loud-in-interviews): the skill only exists when spoken.

**The core truth:** "um" is a turn-holding reflex defending against an interruption that isn't coming. Replace it with a closed-mouth, one-breath pause, drill it against a recording until you can hear yourself, then stress-test it against live follow-up questions. A week of honest reps beats a year of knowing better.

## Frequently asked questions

### How do I stop saying um in an interview?

Replace it with a silent pause: when you feel the "um" coming, close your lips, take one nasal breath, then continue. Drill it by recording answers, counting your fillers, and re-recording until the count drops — then pressure-test with live mock interviews, because fillers return under stress unless you practice under stress.

### Do filler words matter in an interview?

A handful don't — normal speech contains two to three per hundred words and interviewers produce them too. High density matters: answers stuffed with "um, like, basically" run longer, pull attention away from your content, and make you sound unsure of things you actually know.

### Why do I say um so much when nervous?

Fillers are turn-holding signals: your brain uses them to buy planning time without surrendering the floor. Nerves shrink your planning capacity, so you need more of them — but in an interview nobody is trying to take the floor from you, which is why a silent pause works just as well.

### What should I say instead of um?

Nothing. A one-second silent pause buys the same thinking time and reads as composure rather than doubt. If you need a longer beat on a hard question, name it once — "let me think about that for a second" — and then actually pause.

### How many filler words per minute is normal?

Conversational speech averages roughly two to three fillers per hundred words — around four to six per minute of speaking. Below that, nobody notices. If a two-minute answer contains fifteen or more, the fillers have become the message, and it's worth a week of drills.

### Does pausing in an interview look bad?

No — it reads as thinking, which is exactly what interviewers want to see. Candidates consistently overestimate how long their pauses feel: a gap that feels like an eternity to you registers as about one composed second to the listener.

Filler words vanish when you can hear yourself and pause under pressure. [Greenroom](https://usegreenroom.app/) runs spoken mock interviews with Ari — live follow-ups, feedback on delivery and substance. Free to start.
