Presentations and Public Speaking: The Secrets of Speech Writing

Eye Contact
Using natural, direct eye contact helps your audience feel connected to you.
Gestures
Gestures can help you paint pictures with words, but make sure they don't get in the way, and they are natural.
Enthusiasm
Be enthusiastic. If you don't care, why should your audience? Your enthusiasm builds your audience's enthusiasm.
Articulation
Articulate your words clearly so the members of your audience will understand you.
Breathe
Breathing helps you control nervousness. It also gives you time to gather your thoughts. Remember that a pause can be used to
provide emphasis.
Posture
Correct posture conveys confidence.
Tone
The tone of your voice can create or change a mood.
Dress
Dress for success. Be neat and professional. Don't wear loud
accessories that will distract members of the audience.
Language
Use proper language and be careful not to use non-words and fillers such as "um" and "uh" too often.
Smile
A smile will not only make you look and feel better, but also make your audience more receptive.
