Voice Inflection: Your voice should be loud enough that no one in the audience should have to strain to hear you. Project your voice to the back of the room, but don’t shout either. If necessary, arrange to have a microphone available. If the members of your audience cannot hear you, all your preparation is useless.
If your voice sounds enthusiastic, your listeners are more likely to stay tuned in to your message. If you sound indifferent, tired, or monotonous, it will be difficult to capture or retain your audience’s attention.
The same sentence can have multiple meaning depending on which word is emphasized. The emphasis on a particular word implies additional information than what the words say.
• I work on the weekend. (I work then, but you don’t.)
• I work on the weekend. (I don’t sit around or relax — I WORK!)
• I work on the weekend. (Emphasizing when I work, and that I am not free at that time.)
