USING YOUR VOICE EFFECTIVELY: Public speaking does not come natural to most people, in fact most people have a fear and must learn the skill. Using clear and concise language, speaking loudly and clearly, slowing down for important points of your presentation, using a pause, and avoiding monotone speech, projecting your voice, and avoiding filler words such as uhm, are great ways to start enhancing your skill of public speaking. This is all a matter of practice. There is actually a world wide organization called the toastmasters where you can go and practice speeches and receive a good training in a protected environment: www.toastmasters.org
ENGAGING YOUR AUDIENCE: To engage your audience you must understand your audience and use language that tailors to them, “read” your audience and their nonverbal cues, use paraphrasing to confirm your understanding, use questions to encourage interaction from your audience.
