3 common mistakes in public speaking

Public speaking is an art. And like every art, it comes with its own set of unspoken rules. While some mistakes might seem minor to you, they can be glaringly obvious to an audience—especially one that knows a thing or two about effective communication.

These slip-ups don’t just make your presentation less effective—they can also cost you respect and credibility. Let’s look at three common mistakes that public speakers often make, and why you should avoid them:

1. Speaking Even When Your Time Is Up

Yes, your message might be important—but going over time is a quick way to lose your audience’s attention and even their goodwill. When you exceed your allotted time, it shows a lack of respect for the schedule, the organizers, and other speakers waiting their turn.
Your audience came prepared for a talk of a certain length. When you keep going past your slot, you risk sounding self-important or inconsiderate—even if you didn’t mean to. Always plan your talk with a buffer, and learn to wrap up with impact, not with haste.

2. Failing to Acknowledge the Organizers or Previous Speakers

Jumping straight into your speech without first appreciating the conveners or acknowledging the speakers before you is a subtle but powerful mistake. A simple “Thank you to the organizers for this opportunity,” or “Let me first appreciate the insightful points made by the previous speaker,” goes a long way.
It shows humility, gratitude, and professionalism. Plus, it helps you connect with the room before launching into your own message. Think of it as a respectful handshake before you start your conversation.

3. Using Too Much ‘Big Grammar’

Trying to sound intelligent by using complicated vocabulary can easily backfire—especially if your audience can’t follow your message. Public speaking is not the time to show off your dictionary skills. If your words need to be decoded, you’ll lose your listeners.
The best speakers simplify complex ideas without dumbing them down. They aim for clarity, not confusion. Always ask yourself: “Will my audience understand this term?” If not, rephrase it. Remember: It’s not about how fancy you sound, but how clearly you communicate.

In Summary

Great public speakers are not just eloquent—they’re thoughtful, respectful, and audience-focused. Avoiding these common pitfalls will not only make you a better speaker but also earn you lasting respect from your listeners.
