## Question

Define public speaking, and list out all the key strategies that helps to deliver an effective public speech.

## Short answer

Key strategies are knowing the purpose and audience, organizing content clearly, using simple language, practicing, controlling nervousness, using effective voice and body language, and ending with impact.

## Answer

**Public speaking** is the process of delivering a planned, structured oral presentation to a live audience in order to inform, persuade, motivate or entertain them.

#### Key strategies for an effective speech

1. **Know your purpose:** decide whether you aim to inform, persuade or entertain.
2. **Analyse the audience:** consider their age, knowledge, interest and expectations, and adjust your language and examples.
3. **Research and organise the content:** collect accurate facts and arrange them into an introduction, body and conclusion.
4. **Start strongly:** open with a question, a story, a fact or a quotation that catches attention.
5. **Use simple language:** short sentences, familiar words and clear examples.
6. **Practise and rehearse:** rehearse aloud, time yourself, and if possible practise in front of friends or a mirror.
7. **Control nervousness:** breathe deeply, prepare well, think positively and treat the audience as friendly.
8. **Use good voice control:** vary the pitch, volume and speed, and use pauses for emphasis.
9. **Use effective body language:** stand straight, make eye contact, and use natural gestures and facial expressions.
10. **Use visual aids wisely:** slides, charts or models to support, not replace, your speech.
11. **Involve the audience:** ask questions, use humour where suitable and notice their reactions.
12. **Keep to the time limit:** a short, focused speech is better than a long one.
13. **Dress appropriately** and arrive early to check the equipment.
14. **End with impact:** summarise the main points, then close with a memorable thought or call to action.
15. **Handle questions politely** and seek feedback to improve.
