Most people will never address a stadium or give a famous conference talk, but almost everyone in business needs to speak effectively in front of others. Owners pitch to customers, lenders and investors. Engineers explain designs to clients and production teams. Managers brief staff, run meetings and present results. Salespeople present proposals. Employees put ideas to their managers. In each case, the ability to speak clearly and confidently influences decisions, careers and revenue.
Public speaking is a learnable skill, much like riding a bicycle. Children do not learn to cycle to win races. They learn because it builds balance, coordination and confidence, and lets them join in with friends. Similarly, you do not need to aspire to be a famous speaker to benefit from speaking well. It helps you explain your views, persuade your boss, deliver effective presentations, contribute in discussions and build relationships.
This article covers why speaking skills matter, the foundations of a good presentation, the 5 Ps of preparation, a structure for engaging audiences, voice and body language, handling questions and nerves, and practical exercises.
Why speaking skills matter
Effective speaking helps you:
- Achieve professional goals, such as winning work, gaining approval and earning promotion.
- Share ideas and influence decisions.
- Build credibility and trust.
- Strengthen relationships with customers, colleagues and partners.
- Lead teams through clear direction and inspiration.
Good presentations also build relationships, and relationships lead to both revenue and opportunities.
Foundations: passion, purpose and something to say
Three foundations underpin effective speaking.
Passion. People who care about their topic and want to learn speak with energy. If you are not interested, your audience will not be either.
Purpose. Know why you are speaking: to inform, persuade, inspire, teach or decide. Purpose sustains you through preparation and practice, much as a genuine personal reason, not a friend’s encouragement, keeps someone going to the gym when training gets hard.
Something worth saying. Your experience, ideas and solutions can help others. Do not keep valuable thoughts to yourself because you are shy, introverted or worried about what people will think. Aim to be a giver: someone who adds value, shares ideas and solves problems through what they say.
Know your audience and your purpose
Before preparing anything, answer:
- Who is the audience? Board members, customers, technical staff, students, the general public? What do they already know, and what do they care about?
- What is the purpose? What should the audience think, feel or do afterwards?
- What is the setting? Room size, time available, equipment, formal or informal?
- What language and level suit them? Use the language your audience is most comfortable with, avoiding jargon unless the audience shares it.
If you are new to speaking, start with topics you know deeply. When you speak about your own expertise, you can answer questions confidently. When you speak about unfamiliar topics, you tend to sound memorised and become nervous when questioned.
The 5 Ps of presentation preparation
1. Plan. Decide what you will say, how you will say it, what the audience should take away and what response you expect.
2. Prepare. Research the content, facts and data thoroughly. Audiences notice gaps and errors. Prepare clean, simple slides and test any video or audio clips.
3. Practise. Rehearse many times before presenting, out loud and ideally on your feet. Many experienced presenters rehearse important presentations ten or more times. Practice builds fluency and confidence, and reveals where the flow does not work.
4. Present fully. On the day, give it your full energy and attention. Hold nothing back.
5. Be positive. Expect that your audience will understand and value what you have to say. Confidence is contagious.
A structure that engages: attention, relevance, confidence, satisfaction
John Keller’s ARCS model, developed for instructional design, offers a useful structure for presentations.
Attention. Open with something that grabs attention: a story, a striking fact, a question or a demonstration. One presenter opens with a story about a woodcutter whose output kept falling. When the audience suggests he was tired, or had too many trees, the presenter reveals the moral: the woodcutter never stopped to sharpen his axe, and the real question is how sharp our own capabilities are.
Relevance. Show the audience why the topic matters to them. “This pen is for sale” does not engage anyone. “This pen will make your signature on every contract feel effortless” connects to the listener. Relevance answers the silent question every audience asks: what is in it for me?
Confidence. Speak as someone who knows the subject, using facts and evidence in simple language. If you do not believe in your message, nobody else will.
Satisfaction. Leave the audience feeling their time was well spent: they learned something useful, made progress on a decision or felt inspired.
A simpler way to think about structure is a strong opening, a fact-based body organised into a few clear points, and a memorable close that summarises the key message and states the next step.
Engage the audience
- Tell stories. Stories paint pictures in listeners’ minds and are remembered long after facts are forgotten. Many great speeches are built around stories.
- Ask questions and invite participation, so people feel involved rather than lectured.
- Use visual aids that support your message: clear slides, diagrams, short videos or physical samples.
- Read the room. If the audience is distracted when you arrive, such as students chatting or executives on their phones, engage them before launching into your content. Adapt your plan to the situation rather than reciting it regardless.
Voice: your most important instrument
Your voice conveys confidence and creates confidence in your audience. Work on five elements:
- Pitch and volume. Speak clearly and loudly enough to be heard, but do not shout. With a microphone, use normal volume, because forcing your voice through amplification can distort it.
- Pace. You have no train to catch. Speak at a measured pace that lets people follow and gives you time to think. Rushing loses listeners, and speaking too slowly bores them.
- Pauses. Use deliberate pauses to let important points land and to collect your thoughts. A short pause before answering a difficult question is better than rushing into a poor answer. Long, frequent silences, however, create “dead air” and suggest you are unprepared.
- Emphasis. Stress the words that carry your message. Words have impact only when delivered with appropriate emphasis.
- Variation and expression. Vary your tone, pace and volume to match the content. Monotone delivery bores audiences. Let your voice reflect your facial expression: warm when sharing good news, serious when discussing risks.
Voice exercises
- Read aloud daily, for example from a children’s book with varied language, recording yourself and listening back.
- Articulate clearly, slowing down to pronounce each word fully.
- Relax your face and jaw with gentle stretching before speaking.
- Breathe from the diaphragm: breathe deeply into your abdomen and speak on a steady outward breath, so your voice stays strong and steady.
- Stand or sit upright, which allows your voice to project.
- Warm drinks before speaking can help keep your voice comfortable.
Theatre or speaking clubs, such as Toastmasters, offer structured voice and speaking practice in a supportive setting.
Body language and use of the stage
- Posture: stand upright and balanced, and avoid slouching or leaning on furniture.
- Gestures: use natural hand movements to emphasise points, but avoid constant waving or fidgeting.
- Movement: in a large space, move purposefully from one position to another rather than pacing constantly or standing frozen. In a small room, limit movement. Avoid turning your back to the audience.
- Eye contact: look at different people around the room for a few seconds each, so everyone feels included.
- Facial expression: a genuine smile signals confidence and warmth.
- Slides: do not read every word on your slides. The audience can read faster than you can speak. Use slides as prompts and visual support.
Practical checklist for the day
- Arrive early to check the room, equipment, microphone and sound.
- Test your slides and videos on the actual equipment.
- Dress comfortably and appropriately for the audience. Avoid outfits so striking that they distract from your message.
- Eat lightly beforehand and keep water nearby.
- Breathe slowly and deeply for a few minutes before starting.
- Engage the audience before diving into content.
- After the presentation, provide resources such as handouts, links or a feedback form, and follow up on any commitments.
Handling questions
- Listen to the whole question before answering.
- Repeat or rephrase questions in larger rooms so everyone hears them.
- Answer concisely and check that you have addressed the question.
- If you do not know the answer, say so, and offer to follow up. Buying time honestly is far better than bluffing.
- Invite others’ views when appropriate. An audience poll or discussion can be valuable.
- Handle disruptive participants politely. Acknowledge them, offer to discuss further afterwards, and return to your topic.
Managing nerves
Almost everyone feels nervous before speaking, including experienced presenters. Nerves are energy that can be channelled into a lively presentation. Practical techniques:
- Prepare thoroughly. Confidence grows from knowing your material.
- Rehearse out loud, including the opening, which is often when nerves are strongest.
- Practise in front of a mirror, then record yourself on video and review it. You will spot strengths and weaknesses, and seeing yourself improve builds confidence.
- Talk to yourself constructively before speaking. Remind yourself of your purpose and preparation.
- Breathe: slow, deep breaths calm the body.
- Focus on the audience’s needs, not on yourself.
- Start with friendly faces: make early eye contact with people who look receptive.
- Accept imperfection. Audiences forgive small mistakes and rarely notice them.
Presentations for technical people
Engineers, scientists and technical specialists often present complex material to non-specialist audiences such as customers, managers or investors. Adapt by:
- Leading with the conclusion and its implications, then supporting it with technical detail.
- Translating technical results into business outcomes: cost, time, risk, safety and quality.
- Using visuals, such as diagrams, photos and prototypes, rather than dense data tables.
- Keeping detail in reserve in appendices or backup slides for questions.
- Testing the presentation on a non-specialist colleague before the real audience.
Practice exercises
- Mirror and record: choose a short topic, speak for two minutes in front of a mirror, record it and review it.
- Read widely: the more you read, the more you have to say, and the more confidently you can discuss many topics.
- Group practice: present to friends or colleagues and ask for constructive feedback. Discuss rather than argue.
- Breathing practice: practise slow breathing daily to stay calm under pressure.
- Small regular opportunities: volunteer to speak at team meetings, introduce speakers or give short updates. Each small experience builds confidence.
- Impromptu practice: ask a friend to give you an unexpected topic, then speak about it for two minutes with a clear opening, two points and a close. This builds the ability to think on your feet in meetings and question sessions.
A worked example
A production manager at a food manufacturer must present a proposal to the board for a new packaging line. In past board meetings, she has read from dense slides and struggled with questions.
This time, she plans around one message: the new line will remove a bottleneck that is costing contracted sales. She opens with a short story about an order the business had to decline last month. She explains relevance in board terms of revenue, margin and customer retention, presents three supporting points with simple charts and keeps the engineering detail in an appendix. She rehearses eight times, including once in front of a colleague from finance, who asks the questions the board is likely to ask. On the day, she arrives early to test the screen, speaks without reading her slides and answers questions calmly, offering to follow up on one detailed cost query.
The board approves the project, and the chair comments on the clarity of the presentation.
Summary
Speaking well is a learnable skill that pays off throughout a career. Build on passion, purpose and something worth saying. Know your audience, prepare with the 5 Ps (plan, prepare, practise, present fully and stay positive) and structure your talk to gain attention, show relevance, build confidence and leave the audience satisfied. Engage people with stories and questions, use your voice and body deliberately, handle questions honestly and manage nerves through preparation and practice. Start small, practise often and keep improving.
