How to stop saying um
Everybody says um. It is not a character flaw, it is the sound of thinking out loud. But a take with twenty of them is harder to listen to than the same take with five, and the good news is that fillers respond to practice faster than almost any other speaking habit.
The short answer: Replace the filler with a pause. Fillers happen when your mouth keeps going while your mind looks for the next words, so the fix is to let the silence happen instead. End sentences fully, slow down the first ten seconds, and count your fillers on a one-minute take each day. Most people halve them in a few weeks.
Why fillers happen
A filler is a placeholder. Your brain is choosing the next words, and your mouth fills the gap so nobody takes your turn. That is why fillers cluster at the start of a sentence, right after a question, and when you switch from one thought to the next. They are a sign you are planning, not a sign you do not know what you are talking about.
Not every filler is a sound. Like, you know, basically, I mean and so do the same job when they are not carrying meaning. So does repeating the start of a sentence: "I was, I was going to say". Listeners hear all of these the same way, as a small wait.
Pause instead
The single most useful change is to let silence do the job the um was doing. A one-second pause feels long to you and sounds normal, even confident, to the person listening. It also gives your brain the time it was asking for.
Practice it on purpose: at the end of every sentence, close your mouth for a beat before you start the next one. It will feel slow for a few days. Then it will feel like you.
Land the sentence
Fillers pile up where sentences run on. "And so, um, and then, like, the thing is" is one sentence that never ended. Finish the thought, let your voice drop at the full stop, and start a new one. Shorter sentences give you more natural places to breathe, and every breath is a place an um used to go.
Slow the first ten seconds
Most fillers arrive while you warm up. Know your first sentence before you start and say it a little slower than feels natural. Once the first line lands cleanly, the rest of the take tends to follow it.
Count them
You cannot fix what you cannot hear, and almost nobody hears their own fillers in the moment. A count makes them visible. Quant100 counts every filler on a take you keep as is, shows which words you lean on most, and draws the count on the video as it climbs. Seeing "like ×9" once is usually enough to start catching it.
Watch the number, not every word. One take a day, a minute or longer, and look at your fillers a minute week over week. Going from six a minute to two is a big change that listeners feel, even if they could not say why.
Make it a game
Try the zero challenge: one minute with no fillers at all, kept as is. It is harder than it sounds and easier than you fear. If you get there, you can put the take on the clean board, where the cleanest public takes on Quant100 are ranked by fillers per 100 words.
Questions
Is it bad to say um?
No. A few are normal and nobody notices them. It only gets in the way when there are enough of them that a listener starts to hear them instead of what you are saying.
How many filler words is normal?
In relaxed conversation many people say several a minute. On camera, under two a minute sounds polished and under one sounds very clean.
What counts as a filler word?
Um, uh, er and hmm always. Like, you know, basically, I mean and so when they are filling a gap rather than carrying meaning. Repeating the start of a sentence by accident counts too.
