1. Pauses Aren’t Silences — They’re Cues

• When you pause, natives don’t hear “silence” — they hear why you paused.
• For the native speaker, pauses normally occur as unforced as breathing or for dramatic effect. Example: “So… here’s the thing.”
• For the non-native, pauses usually happen as a function of processing — searching for the word, thinking through the translation, or checking grammar twice.
• Even if your English is excellent, the reason for the hesitation somehow doesn’t sound the same, and natives subconsciously pick up on that.

2. Filler Words Are Cultural Customs

The most common fillers in English are “uh,” “um,” “like,” “you know,” “so,” and “I mean.” They are not random sounds — they are keeping pace with language. A native uses them in more or less automatically:

• “I was, like, super tired.”
• “So, you see, we just left.”

Learners sometimes:

• Employ no fillers whatsoever (which reads a bit stilted or mechanical).
• Employ fillers from their home language (“ehm,” “ano,” “eto,” etc.).
• Or create odd ones, such as “How to say…” in the middle of a sentence.
• All of these get natives to notice: “Oh, this person’s background is different.”

3. Timing Is Everything

Native filler words are short and fall into the speech rhythm. The non-native speaker will extend a pause a little too long before saying “uhhh…” or place it in an odd spot. For example:

• Native: “So, um, do you want to go?” (filler keeps the flow).
• Non-native: “So… do you, uh… want to go?” (larger pause, not so smooth).

Small differences like this don’t stop communication, but they leap out like an accent for timing.

4. Why Natives Pick Up So Quickly

• Pattern recognition: From early childhood, natives get used to exactly how fillers and pauses sound. Anything else that breaks the pattern jumps out immediately.
• Emotional reading: Pauses and fillers also communicate mood — hesitation, uncertainty, enthusiasm. If yours are different from native patterns, they’ll misread your emotions.
• Unconscious bias: People sometimes equate unusual pauses with nervousness or formality, even if you’re just thinking carefully.

5. The Double Standard

Here’s the funny part: natives use fillers constantly, but they don’t notice them in each other. When a learner does something slightly different with fillers, though, it stands out more because it breaks the expected rhythm. So what natives take for granted in themselves suddenly becomes a marker in you.

6. Why This Isn’t a Bad Thing

Being noticed as non-native because of pauses or fillers doesn’t make you “wrong.” Quite the opposite:

• Your pauses before speaking usually make you sound more thoughtful.
• Your exclusion of filler words makes you sound clearer and more professional.
• And your own fillers sometimes amuse people because they’re different.

The Bottom Line

Fillers and pauses are such an invisible glue of language. Natives don’t consciously consider them, but they’re instructed to differentiate “native hesitation” from “non-native hesitation.” It’s because of this that your English can sound alien even when your grammar and vocabulary are impeccable.

But instead of worrying, reflect on this: your pauses and fillers are small fingerprints of your multilingual brain at work. They don’t make you less fluent — they just mean you’ve traveled a longer, richer pathway to fluency.
