How to cut mistakes and filler words
“Um”, “like”, “you know”, a slip mid-sentence — they make even a useful video sound unsure. Here's where they come from, how to say fewer of them while filming, and how to cut the rest in a couple of minutes.
Where filler words come from
Filler words are the sound your brain makes to fill a gap while it finds the next word. “Um”, “uh”, “like”, “so”, “you know”, “basically” — everyone uses them. In conversation nobody notices; in a video they jump out.
Slips happen for the same reasons: you're thinking about the next line, you're nervous on camera, or you're trying to get a long sentence out on one breath. It doesn't make you a bad speaker — that's just how real speech sounds.
What to cut and what to keep
Cut everything and your speech turns robotic: no breaths, no connectors, no rhythm. So cut what gets in the way of the message:
- “um” and “uh” at the start or in the middle of a line;
- repeats: “I… I think”, “this, this matters”;
- a wrong word you corrected right away;
- the start of a line you abandoned and said again.
Connectors like “and so” or “which means” can stay if the line sounds abrupt without them. Trust your ears: if it sounds natural after the cut, you got it right.
How to speak cleaner while filming
Fewer extra words in the recording means less work later. A few habits that help right away:
- Swap “um” for silence. Pausing for a second to think is fine — a pause is easy to cut, an “um” is harder.
- Speak in short sentences. The shorter the line, the less room to get tangled.
- Keep the text in front of you. When you don't have to recall the next idea, filler words have nowhere to come from.
- Tripped up? Say the whole line again. Don't patch it mid-sentence — start over without stopping the recording.
- Film each line a few times. One of the takes almost always comes out clean.
Cutting extra words by hand
In a regular video editor you find every “um” by ear: listen, pause, make two cuts on the audio track, delete, close the gap. Short words are easy to miss — you clip a bit of the next word or leave half the sound behind.
That's why cleaning up speech by hand eats more time than anything else when editing talking videos, and people often give up halfway.
How to cut words by text
Text-based editing is simpler: the AI transcribes your speech and knows where each word starts and ends. You see what you said as words — and cut right on them, like editing a note.
That's how it works in Dubl: open a line, tap the extra word, and it's gone from the video — even mid-sentence. The cut word stays in the text, struck through: tap again and it's back. Only whole words are cut, so the ones around it stay intact.
What else helps
- Best take. If you filmed a line several times, the AI marks the complete, clean take with a star — often there's nothing left to cut.
- “Not in video”. Slips the AI set aside while splitting your takes wait there with a reason — bring any back in one tap.
- “Smart” captions. Filler words don't appear in them, even if you left them in the audio.
- Pauses. Dubl removes silence longer than your threshold on its own, so the video doesn't drag.
How to do it in Dubl
- Add your takesFilm with the teleprompter or pick videos from your gallery — the AI transcribes your speech and marks the best takes.
- Open a lineOn the editing screen pick a line and tap “Trim”.
- Tap the extra words“Um”, a repeat, a slip — each word is struck out with a single tap.
- Save your videoThe video joins up without those words and the captions update on their own.
