7 lỗi sai nghiêm trọng khi thuyết trình trước công chúng và cách khắc phục chúng

Even experienced speakers make mistakes. The difference between good and great public speakers is often their ability to recognize and fix common problems.

In this guide, we'll cover the seven most common public speaking mistakes and practical strategies to fix each one.

1. Speaking too fast

Vấn đề: Nervous speakers often accelerate, racing through their material. This makes it hard for the audience to follow and understand.

Cách khắc phục:

  • Practice with a metronome or timer to establish an appropriate pace
  • Record yourself and listen back to gauge your speed
  • Deliberately slow down, especially during important points
  • Use pauses strategically between ideas
  • Remember: your audience can only absorb information at a certain speed

2. Not making eye contact

Vấn đề: Speakers who look at their notes, the screen, or anywhere but the audience disconnect from their listeners. This reduces trust and engagement.

Cách khắc phục:

  • Know your material well enough that you only need occasional glances at notes
  • Practice making eye contact with different audience members
  • Hold eye contact for 3-5 seconds before moving to another person
  • Distribute eye contact around the room, not just the front row
  • Remember: people trust and connect with those who look at them

3. Using filler words (Um, uh, like)

Vấn đề: Filler words distract the audience and make you sound less confident. They break the flow of your speech and undermine your authority.

Cách khắc phục:

  • Become aware of your filler word habits through recording yourself
  • Replace filler words with strategic pauses
  • Practice pausing when you want to fill silence with "um"
  • Slow down to give yourself time to think without filling silence
  • Be patient with yourself; breaking this habit takes practice

4. Poor body language

Vấn đề: Standing rigidly, pacing nervously, or crossing your arms creates a disconnect between your words and your nonverbal communication.

Cách khắc phục:

  • Make intentional movements that support your message
  • Avoid pacing or fidgeting, which signals nervousness
  • Use open body language with uncrossed arms
  • Plant your feet or move deliberately to different areas
  • Practice until confident, relaxed body language feels natural

5. Overloading slides with text

Vấn đề: Text-heavy slides force the audience to choose between reading and listening. Most will read, which means they're not listening to you.

Cách khắc phục:

  • Limit each slide to 3-5 key bullet points maximum
  • Use images or diagrams instead of text when possible
  • Keep font size large enough to read from the back of the room
  • Remember: your slides support your spoken words, not replace them
  • Include blank slides when you want full attention on you

6. Ignoring audience engagement

Vấn đề: One-directional presentations where the speaker talks and the audience listens passively lead to disengagement and poor retention.

Cách khắc phục:

  • Ask rhetorical questions to engage thought
  • Include interactive elements like polls or discussion
  • Invite audience participation and questions
  • Tell stories that audiences can relate to
  • Watch for signs of disengagement and adjust energy accordingly

7. Weak opening or closing

Vấn đề: Audiences form first impressions in the opening and remember what they heard last. Weak openings and closings waste these critical moments.

Cách khắc phục:

  • Strong opening: Start with a story, surprising statistic, or provocative question. Avoid "Thank you for inviting me"
  • Strong closing: End with a clear summary, call-to-action, or memorable statement. Avoid trailing off
  • Practice your opening and closing until they're polished and natural
  • Make your opening and closing consistent with your presentation style
  • Remember: people remember what you say first and last most clearly

How to identify your own mistakes

Ghi lại chính mình: The most effective way to identify your mistakes is to watch yourself present. You'll notice habits and issues you wouldn't otherwise see.

Yêu cầu phản hồi: Have a trusted colleague or friend watch and provide honest feedback about what they noticed.

Tập trung vào một việc tại một thời điểm: Don't try to fix everything simultaneously. Pick the biggest issue and focus on improving that first.

The path to better presentations

Great public speakers aren't born; they're developed through practice and feedback. Every presentation is an opportunity to improve. Each time you speak:

  • Identify one thing that went well
  • Identify one thing you can improve
  • Practice the improvement before your next presentation

This iterative approach leads to continuous improvement and greater confidence over time.

Remember: even great speakers continue to refine their skills. Your willingness to identify and fix mistakes is what separates good speakers from exceptional ones.
