Mastering public speaking

TL;DR

Summary

Public speaking techniques centered on the 4 organs of communication: eyes, mouth, hands, feet. Complemented by methods for managing stress, structuring your speech, and adapting to context.

Goal

Understand how to be more captivating when speaking in front of an audience, whatever the situation: team meeting, conference, or video call.

The 4-organs method

Public speaking rests on a simple principle: your body communicates as much as your words. For several years I’ve been using a framework I call the 4 organs of communication: eyes, mouth, hands, and feet. Each organ plays a specific role and, if you master them one at a time, you’ll progress very fast.

Definition: Public speaking refers to any situation where one person addresses a group, whether 3 colleagues in a meeting room or 500 people in an auditorium. The fundamental mechanics stay the same.

This framework has the advantage of being concrete. Rather than telling you to “be charismatic”, I’d suggest working on physical elements you can observe and correct.

The eyes

Eye contact is the first connection tool with your audience. When you look someone in the eye, that person feels considered, involved. Conversely, a speaker who stares at their notes or the back of the room loses the audience immediately.

The 3-second rule

The basic technique: rest your gaze on one person in the audience for 2 to 3 seconds, then move to another. Not shorter (looks shifty), not longer (intimidating). Doing this regularly creates a sense of personal conversation with each member of the audience.

Structured scanning

For a large audience, mentally divide the room into 3 zones: left, center, right. Rotate your gaze between these zones so nobody feels forgotten. A common mistake is to only look at people in the front row or those who nod. Force yourself to include the people in the back and on the sides.

Practical exercise: the triangle

At your next presentation, identify 3 people spread across the room (one on the left, one in the center, one on the right). Rotate your gaze between these 3 people during the first minute. Once that’s locked in, expand to 5, then to the whole room.

Reading your audience

Advanced tip: your gaze isn’t just about projecting, it’s also about receiving. Watch faces. Who’s following with attention? Who’s tuning out? Who’s frowning? These signals let you adjust your speech in real time: speed up if the audience is bored, rephrase if they seem lost, pause if they need to absorb. It’s a skill that connects to active listening: knowing how to pick up nonverbal signals from the person in front of you.

The mouth

Your voice is your main instrument. Two parameters to master: volume and pace.

Speak loud, don’t shout

Speak loud enough that everyone can hear you comfortably. In practice, that means speaking one notch above your usual conversational volume. When you speak loud, you project conviction. When you mumble, even brilliant content loses impact.

A good test: ask someone to stand at the back of the room during your rehearsal. If they have to strain, turn it up.

The power of silence

Silence is a powerful tool that beginner speakers underuse. A 2 to 3 second pause after a strong idea lets your audience absorb it. It also creates a dramatic effect that reinforces your message.

Research from Chris Anderson’s team (head of TED) shows that the best TED speakers use an average of 3 to 4 meaningful pauses per minute. These silences are intentional and prepared.

Vary your pace

A monotone delivery puts your audience to sleep. Vary your pace: speed up slightly when telling an anecdote, slow down when stating a key point. This contrast keeps attention.

The “uhm” problem

Filler words (“uhm”, “so”, “you know”) betray a lack of preparation or confidence. The fix: replace every “uhm” with a silence. A silence projects mastery, an “uhm” projects hesitation.

Practical exercise: film yourself for 3 minutes talking about a topic you know well. Count your “uhms”. Redo the exercise focusing only on eliminating these filler words. After 3 to 4 takes, the count drops drastically.

Diction and articulation

Take time to articulate. Rushed speakers swallow the end of their sentences, which tires the audience and reduces understanding. A classic exercise: read a text out loud, exaggerating each syllable like a stage actor. Then read it normally: your articulation will have naturally improved.

The hands

Hands are the amplifiers of your speech. Used well, they reinforce your words. Used poorly, they become a source of distraction.

The golden rule: hands apart

When you speak, your hands should not touch each other. The only moment they can come together is when you’re in a listening posture (for example during an audience question). This simple rule eliminates the majority of fidgety gestures: rubbing your hands, playing with a ring, crossing your fingers.

Don’t hold anything except a microphone or a presentation remote. No pen, no water bottle, no phone.

The gesture frame

Imagine a rectangle 60 cm wide and 100 cm tall, placed in front of your torso. That’s the zone where your hands should move. Below it, your gestures look timid. Above it, they look excessive. Inside it, they’re natural and readable.

Illustrate, don’t decorate

Use your hands to illustrate your point. When you talk about growth, show a rising curve. When you list, count on your fingers. When you compare two options, place them on either side of your body. Your gestures should mean something, not just fill space.

Watch the following video to see how a speaker uses their hands to communicate, even when the verbal content is minimal:

Practical exercise: the gesture library

Watch 3 to 5 TED talks focusing only on the speakers’ hands. Note the gestures that stand out. Then, in front of a mirror, reproduce those gestures while speaking. The goal isn’t to copy, but to build a library of gestures you can naturally draw from.

Advanced tip: if you struggle to lift your arms from your body, start your rehearsals holding your hands open in front of you, palms up, at chest height. From this starting position, it’s much easier to launch into gestures.

The feet

The feet are the foundation (literally) of your posture. It’s the last organ on the list, but often the first to work on because it sets up everything else.

Anchoring

Your feet should be shoulder-width apart, flat on the floor. Your weight is evenly distributed between the two feet. Your pelvis is straight, your hips are still. No swaying left and right, no micro-shuffling, no shifting weight from one foot to the other.

This anchor projects stability and confidence. Conversely, a speaker who sways or paces aimlessly looks nervous or unprepared.

Why it’s so hard

Stress triggers an adrenaline surge that makes you want to move. Micro-shuffling is the physical expression of that nervousness. By focusing on your feet, you break the loop: the body sends a stability signal to the brain, which in turn lowers the stress sensation. It’s a virtuous cycle.

Intentional movement

Advanced tip: once anchoring is mastered, you can integrate movement. But every movement should be intentional. You start at point A, move to point B, and re-anchor at point B. Movement is a transit, not a permanent state.

These movements can support your speech: change position when you change parts, step closer to the audience for a personal anecdote, step back slightly for an overview.

Practical exercise: the 3 spots

Place 3 marks on the floor (post-its, pieces of tape). Rehearse your presentation moving from one spot to the next only during transitions between parts. At each spot, anchor for at least 30 seconds before moving on. This exercise teaches you to dissociate movement and speech.

Managing stress and stage fright

Even the most experienced speakers feel stress before speaking. The difference is they have techniques to channel it.

Diaphragmatic breathing

The most effective technique is diaphragmatic breathing. Just before speaking, take 2 to 3 deep breaths:

1. Inhale through the nose for 4 seconds, expanding your belly (not your chest)
2. Hold your breath for 2 seconds
3. Exhale through the mouth for 6 seconds, drawing your belly in

This technique activates the parasympathetic nervous system, the body’s natural stress brake. Within 30 seconds, your heart rate drops and your voice stabilizes.

Power poses

Researcher Amy Cuddy (Harvard Business School) popularized the concept of power poses: expansive postures that increase confidence. The scientific findings are debated, but many speakers report a real subjective benefit.

The principle: 2 minutes before you speak, isolate yourself and adopt an open posture: feet apart, hands on hips (the Superman pose), or arms raised in a V. Even if you’re skeptical about the science, simply taking 2 minutes to breathe and stand tall before going on stage is beneficial.

Memorize the first 2 minutes

The opening is the most stressful moment. Your voice trembles, your ideas blur, stage fright peaks. The fix: memorize the first 2 minutes of your speech. Word for word. This gives you a safety net so you can start on autopilot while the stress comes down.

Rehearse at least 4 times. Studies on retention show it takes about 5 to 7 spaced repetitions to anchor a text in memory. Plan your rehearsals over 2 to 3 days before D-day.

Stress is your ally

Don’t try to eliminate stress. It’s impossible and counterproductive. Stress brings energy, sharpness, intensity. Your goal is to channel it, not suppress it. A speaker with no stress is often a boring speaker.

Structuring your presentation

The rule of 3

The human brain easily remembers information grouped in threes. The best speeches are organized in 3 parts, with 3 main arguments. Steve Jobs systematically structured his keynotes in 3 acts. The most-shared TED speakers follow the same pattern.

In practice: identify your 3 key messages before preparing your slides or speech. If you have more than 3 ideas, group them. If you only have one, find 2 complementary angles.

The narrative arc

A good speech tells a story, even when the topic is technical. The classic narrative arc:

1. The starting situation: the world as it is today, with its problems
2. The tension: why this problem matters, what it costs, what we lose if we do nothing
3. The resolution: your proposal, your solution, your vision

This is exactly the structure of the pitch, adapted to a longer format. Whether you’re presenting a quarterly review or a new product strategy, this structure works.

The single message

If your audience could only remember one sentence from your presentation, what would it be? That sentence is your single message. Everything else in your speech has to support, illustrate, and reinforce it.

Repeat that message at the beginning, in the middle, and at the end of your presentation. Repetition isn’t a flaw: it’s a teaching tool.

Adapting to context

The small meeting (3 to 10 people)

In a small group, the format is more conversational. You can sit, ask questions, interact directly. Eye contact is easier to manage, but silences are harder to hold.

Key points:

• Use first names of the people you’re talking to, to personalize your inputs
• Ask questions regularly to keep engagement up
• Tone down your gestures: in a tight space, broad gestures look excessive

The conference (50+ people)

In front of a large audience, the physical distance forces you to amplify everything: voice, gestures, facial expressions. What feels natural in a small group is invisible 20 meters away.

Key points:

• Amplify your gestures by 30 to 50% over your natural baseline
• Slow your pace: sound takes longer to reach the back rows
• Use the stage: move between your anchor points to occupy the space

The video call

Remote formats come with specific constraints:

• Look at the camera, not the screen. It’s counterintuitive but it’s the only way to create eye contact with your remote audience
• Frame yourself correctly: your face should take up about a third of the screen, with space above your head
• Mind your lighting: a light source facing you (not behind) avoids the silhouette effect
• Keep gestures within camera frame
• Exaggerate your facial expressions by 20%: the screen flattens emotions

On video, attention is even more fragile than in person (notifications, emails, other tabs). Shorten your inputs and increase the frequency of interactions: polls, direct questions, hands-on exercises.

Recap: your prep routine

For any speaking engagement, here’s the 5-step routine I’d suggest:

1. Structure: identify your single message and your 3 key ideas
2. Write: draft your first 2 minutes word for word
3. Rehearse: 4 to 5 times minimum, including at least once standing up and out loud
4. Film yourself: spot your fidgety gestures and your “uhms”
5. D-day: 2 minutes of power pose, 3 diaphragmatic breaths, and go
