Speaking: Public Speaking & Presentations C2

Delivering Highly Persuasive, Memorable & Impactful Speeches

Listen to the "Boring vs. Impactful" openings.

What you will learn: At C2, your goal is not just to inform, but to influence. This lesson teaches you to move beyond simple facts and use advanced rhetorical frameworks, emotional connection (Pathos), and vocal delivery (Prosody) to create a speech that is truly persuasive and unforgettable.

From Informing to Influencing

A B2 speaker can give a good, clear presentation. A C2 speaker can change the way an audience thinks and feels. Compare these two openings on the same topic.

THE B2 OPENING (Informative 😐)

"Good morning. Today, I'm going to talk about the problem of plastic waste in our oceans. First, I will discuss the statistics. Second, I will cover the environmental impact. Finally, I will suggest some solutions."

THE C2 OPENING (Impactful 🔥)

"When you drank your coffee this morning, did you throw away the cup? What if I told you that cup... will outlive your grandchildren? That it will join 8 million metric tons of plastic... entering our oceans... every single year."

The C2 opening is memorable because it uses a **personal question** (a hook), creates an **emotional connection** (Pathos), and uses a **dramatic pause** and **vivid numbers** to create impact.

The 3 Pillars of Persuasion (The Rhetorical Triangle)

A C2 speech masterfully balances all three pillars of persuasion, first defined by Aristotle.

1. Ethos (Credibility)

Why should they listen to you? (Authority, Trust, Shared Values)

"Having spent 10 years as a marine biologist, I have seen the devastation firsthand..."

2. Pathos (Emotion)

Why should they care? (Stories, Empathy, Values, Hopes, Fears)

"Imagine a future where our children can't swim in the ocean... a future where the beaches are silent."

3. Logos (Logic)

Why does it make sense? (Data, Facts, Case Studies, Logical Argument)

"The data is undeniable: a 5% reduction in plastic use leads to a 20% drop in local pollution."

Advanced Structure: The "Problem - Agitate - Solution" Framework

Forget the simple "Introduction - Body - Conclusion." A C2 persuasive speech uses a structure designed to motivate. The P-A-S framework is one of the most powerful.

Step 1: PROBLEM

Identify a specific problem the audience already has or knows about. (Uses Logos).

"We all agree that plastic waste is a problem."

Step 2: AGITATE

Make the problem feel urgent, personal, and emotional. (Uses Pathos).

"But it's not just a problem. It's a crisis. It's the microplastics in our food. It's the turtles choking..."

Step 3: SOLUTION

Introduce your idea as the clear, logical, and urgent solution to the pain you just agitated. (Uses Logos + Ethos).

"But there is a way forward. My proposal... is the only viable path to solve this, and here's why..."

Your C2 Toolkit: Rhetorical Devices (Click 🔊)

Tool 1: Anaphora (Repetition at the Start)

Repeating a phrase at the beginning of clauses. It builds rhythm and makes a concept stick.

"We cannot accept this reality. We cannot permit this to continue. We cannot fail the next generation."

Tool 2: Tricolon (The "Rule of Three")

Humans are programmed to remember things in threes. It feels complete and powerful.

"Our plan is simple, effective, and achievable."

"We will invest in our people, innovate in our technology, and inspire our community."

Tool 3: Strategic Pausing & Prosody

The most powerful word in a speech is often... [pause] ...silence. A pause builds suspense, adds weight, and gives the audience time to *think* and *feel*.

Do not use filler words like `um`, `ah`, or `like`. Replace them with a confident, silent pause.
