Verbal Filler

In Model UN and broader public-speaking contexts, verbal fillers are the small sounds and phrases that surface when a speaker is thinking faster than they are speaking, or stalling to recover composure. Common English examples include um, uh, like, you know, basically, sort of, I mean, and the throat-clearing so... at the start of a sentence. Equivalents exist in nearly every language (eh in Spanish, euh in French, äh in German, eto in Russian).

Linguists distinguish filled pauses (um, uh) from discourse markers (like, you know, I mean) and hedges (kind of, sort of). All three reduce perceived fluency and, in a competitive MUN setting, can cost a delegate credibility during moderated caucuses, opening speeches, and press conferences. Chairs and judges often score fluency or rhetoric as an explicit rubric category, and excessive filler is one of the most cited reasons for low marks.

Fillers are not always harmful. Research in conversation analysis (notably Herbert Clark and Jean Fox Tree's 2002 work in Cognition) shows that uh and um can signal upcoming short or long delays respectively, helping listeners parse speech. In diplomatic settings, a measured well... can soften disagreement. The problem is frequency and patterning: a delegate who says like six times per sentence undermines an otherwise strong argument.

Standard techniques to reduce filler use include:

• Strategic silence — replacing um with a one- or two-second pause, which reads as confidence rather than hesitation.
• Pre-speech outlining — knowing the three points you intend to hit reduces the cognitive load that generates fillers.
• Recording and self-review — most speakers underestimate their own filler rate by half or more.
• Substituting transitions — furthermore, however, to that point in place of um and like.

For MUN delegates specifically, filler control is most visible during unmoderated-to-moderated transitions, when speakers are pulled to the front with little preparation time.
