Filler words: why you say "um" — and the two-week fix

Count your "um"s in your next meeting. You can't — that's the whole problem. Filler words are invisible to the speaker and glaring to the audience, which is why everyone's estimate ("I don't say it that much") is wrong by roughly a factor of three.

First the reassurance, then the fix.

Why fillers exist (you're not broken)

"Um" is not a defect — it's a traffic signal. Linguists who study disfluency found fillers do real jobs: holding your turn in a conversation ("I'm not done"), buying planning time while your brain assembles the next clause, and even signaling to listeners that a complex idea is coming. Every language has them: Spanish "este," Japanese "ano," Russian "ну."

So the goal is not zero. Speakers with literally zero fillers sound rehearsed and slightly uncanny. The goal is control: fillers under ~2 per minute are unnoticeable; at 5+ per minute they become the thing people remember about your talk. And in high-stakes settings, each one quietly bills your credibility, because audiences read fillers as uncertainty even when they're just planning noise.

Why you can't just decide to stop

The trap: fillers are produced below conscious awareness, in the same pipeline that adds "-ing" to verbs. Willpower can't reach them mid-sentence. People who try "I'll just stop saying um" report the same result: they think about it for two sentences, then the topic takes over and the ums return.

What works instead is a two-part mechanism: awareness training (make the invisible visible) and pause substitution (give the traffic signal a better vehicle).

The two-week method

Days 1–2: get your real number. Record 60 seconds of unscripted speech — describe your day, explain your job. The speech test counts fillers automatically and gives you a per-minute rate. This number is your "before," and seeing it is genuinely startling. (The app's Articulation Trainer runs the same count on every practice rep, which turns the whole method into a daily two-minute game.)

Days 3–7: learn to hear them. Awareness, not suppression. Re-listen to each recording and count the fillers yourself before checking the AI count. Within days, something shifts: you start hearing the "um" as you say it — then a half-second before you say it. That pre-echo is the skill; everything else follows from it.

Days 8–14: swap in the pause. When you feel the um coming — that planning gap — close your mouth and let the gap be silent. That's it. The pause does everything the filler did (holds your turn, buys planning time) and reads as thoughtful instead of uncertain. It will feel eternal from inside; on the recording it's a beat. Powerful speakers are pause-users, not filler-suppressors — listen to any great interview with this in mind and you'll never unhear it.

The accelerator: impromptu drills. Random topic, 60 seconds, unprepared — maximum planning load, maximum filler pressure. Cutting fillers there is training with weights on; your meetings become the easy version.

The other fillers

"Um" gets the press, but audit your recordings for the whole family:

• "Like" — the planning filler plus a hedge; the double function makes it the stickiest
• "You know," "right?" — approval-seeking tags; fine occasionally, needy at frequency
• "So" as a sentence-starter — a launch-ramp habit; try starting on the content word instead
• "Sort of / kind of" — not fillers but hedges; they soften claims you probably meant fully
• "Basically," "literally," "actually" — intensity filler; each one you cut makes the rest of your words heavier

Same method for all: count, hear, pause.

FAQ

How many filler words per minute is normal?

Conversational speech runs 2–5 per minute and nobody minds. For presentations, under 2/min reads as polished. Broadcast professionals sit near zero-point-something — through exactly the training above, not talent.
