Why is it important to avoid fillers like "um" and "uh" during a speech?

Avoiding fillers like "um" and "uh" during a speech is crucial because their presence can undermine the speaker's confidence. When these fillers are used, it may signal to the audience that the speaker is unsure or unprepared, which can lead to doubts about their credibility and authority on the topic being presented. A smooth and fluid delivery fosters a stronger connection with the audience and enhances the overall effectiveness of the speech.

In contrast, fillers do not enhance one's persona; rather, they can clutter speech and distract from the message. While some may argue that fillers provide necessary pauses for thought, professional speakers generally achieve better pauses for emphasis or reflection without resorting to these distractions. Furthermore, in formal speaking contexts, fillers are typically discouraged, as they are more acceptable in casual conversation but diminish the professionalism expected in speeches.
