Quick summary
Public speaking is speaking to a group in a structured, deliberate way to inform, persuade or entertain. This topic covers types of speeches, preparing and organising a speech, delivery techniques (voice, body language), overcoming stage fear, and model speech outlines for occasions such as welcome speeches and votes of thanks.
Key points
- Purposes: to inform (lecture), to persuade (debate, campaign), to entertain (after-dinner talk), to mark a special occasion (welcome, farewell, vote of thanks).
- Methods of delivery: impromptu (no preparation), extempore (prepared outline, spoken naturally — best for most situations), manuscript (read from text; formal events), memorised (risky; can sound mechanical).
- Preparation: analyse audience and occasion → decide purpose and central idea → collect material → organise → practise aloud.
- Structure: Opening (greet the chief guest and audience, attention-grabber, purpose) → Body (2–3 main points with examples) → Closing (summary, memorable last line, thanks).
- Aristotle's modes of persuasion: ethos (speaker's credibility), pathos (emotion), logos (logic and evidence).
- Voice (paralanguage): volume, pitch, pace, pauses, stress and clear pronunciation. Use pauses before and after key points.
- Body language: upright posture, steady eye contact, open gestures, natural facial expressions; avoid pacing, hands in pockets, reading continuously from paper.
- Stage fear (glossophobia) is common. Remedies: thorough preparation, rehearsal, deep breathing, starting with a well-practised opening, focusing on the message rather than oneself.
- Respect the time limit; end on time.
- Use cue cards with key words rather than full sentences.
