Video: Effective Speaking Strategies: 10 Practical Techniques to Deliver a Memorable Case Presentation

A presentation can be perfectly written and still sound flat. Speaking is not only about words. Judges also hear:

  • pace;

  • volume;

  • emphasis;

  • pauses;

  • tone;

  • energy.

These elements create verbal hierarchy. Just as visual hierarchy tells the audience what to look at, your voice tells them what to listen to. Your voice highlights the argument.

Pace

Not every part of the presentation deserves the same speed. Slow down when delivering:

  • the problem;

  • an important insight;

  • the recommendation;

  • a major financial result;

  • an important risk;

  • the close.

You may move somewhat faster through familiar or lower-value information, but don't confuse speed with confidence. Speaking faster doesn't make you sound smarter. If the judges cannot process what you are saying, the information is lost.

The Speed Trap

Case teams often rehearse over time. The response? Speak faster. That is usually the wrong solution. If a ten-minute presentation takes twelve minutes, you probably have a content problem, not a speaking-speed problem. Return to Chapter 2: The problem isn't time. It's focus. Cut lower-value material, protect the important moments.

Pause

Silence can be powerful. A short pause gives the audience time to process what they have just heard. Consider:

  • "Our analysis identified three possible strategies."
  • Pause.
  • "Only one solves the root cause."

The pause creates emphasis. Use pauses before or after:

  • an important recommendation;

  • a major number;

  • a key insight;

  • a contrast;

  • the final sentence;

  • an important transition.

Don't be afraid of silence.

Emphasis

Don't emphasise every word; choose the words that matter. Compare:

  • "This is not a growth problem. It is a retention problem." The contrast creates meaning.
  • "Even in our downside scenario, the investment generates a positive NPV." The emphasis tells the audience what matters.

Volume

Your volume should be strong enough to reach the entire room. Build for the back row; the principle applies to speaking as much as slide design. You should not sound as though you are shouting, and nobody should have to strain to hear you. Remember, you are ultimately presenting to the judges, who are often seated at the front of the room.

Tone

Your tone should match the message. A serious risk must not be delivered with the same energy as an exciting growth opportunity. Likewise, your recommendation should sound like a recommendation. Compare:

  • "So...we kind of think maybe Option B is probably the best..." with:
  • "We recommend Option B."

The second communicates ownership.

Energy Is Not Volume

Energy doesn't mean:

  • shouting;

  • speaking rapidly;

  • exaggerated gestures;

  • artificial enthusiasm.

Energy comes from:

  • engagement;

  • conviction;

  • variation;

  • presence;

  • genuine interest in the recommendation.

You want the judges to feel that you believe the solution is worth discussing.

Mark the Important Moments

During rehearsal, identify the moments that deserve deliberate vocal emphasis. For example:

  • The Problem: Slow down.
  • The Key Insight: Pause before it.
  • The Recommendation: Deliver clearly and confidently.
  • The Financial Result: Let the number land.
  • The Close: Slow down again.

This prevents the presentation from sounding like ten minutes of uninterrupted information.

Discover Your MAD Skills Principle

If everything sounds equally important, nothing sounds important.

Use your voice to create hierarchy.

The Bottom Line

Use: Pace + Pause + Emphasis + Volume + Tone + Energy to guide the audience. Your voice should help judges hear the structure of your argument even when they are not looking at the slides.
