Know the needs of your audience and match your contents to their needs. Know your material thoroughly. Put what you have to say in a logical sequence. Ensure your speech will be captivating to your audience as well as worth their time and attention. Practice and rehearse your speech at home or where you can be at ease and comfortable, in front of a mirror, your family, friends or colleagues. Use a tape-recorder and listen to yourself. Videotape your presentation and analyze it. Know what your strong and weak points are. Emphasize your strong points during your presentation.
When you are presenting in front of an audience, you are performing as an actor is on stage. How you are being perceived is very important. Dress appropriately for the occasion. Be solemn if your topic is serious. Present the desired image to your audience. Look pleasant, enthusiastic, confident, proud, but not arrogant. Remain calm. Appear relaxed, even if you feel nervous. Speak slowly, enunciate clearly, and show appropriate emotion and feeling relating to your topic. Establish rapport with your audience. Speak to the person farthest away from you to ensure your voice is loud enough to project to the back of the room. Vary the tone of your voice and dramatize if necessary. If a microphone is available, adjust and adapt your voice accordingly.
Body language is important. Standing, walking or moving about with appropriate hand gesture or facial expression is preferred to sitting down or standing still with head down and reading from a prepared speech. Use audio-visual aids or props for enhancement if appropriate and necessary. Master the use of presentation software such as PowerPoint well before your presentation. Do not over-dazzle your audience with excessive use of animation, sound clips, or gaudy colors which are inappropriate for your topic.
