The key to good delivery is a strong desire to communicate with the audience.
Speakers who concentrate on getting their ideas across to their listeners usually
find themselves using good delivery techniques. There are four methods of delivering a speech: memorization, manuscript,
impromptu, and extemporaneous. Of the four, extemporaneous is the most popular
and usually the most effective because the speaker delivers a well-prepared,
well-rehearsed speech in a lively, conversational manner. In delivering a speech, your voice should be loud enough for everyone to
hear, your words should be spoken clearly so that they are easily understood,
and your voice should be expressive so that you sound interesting and lively. Nonverbal communication is the message you give with your body by means
of personal appearance, eye contact, facial expressions, posture, movement,
and gestures. All these elements should convey confidence and a positive regard
for the audience. Of special importance is eye contact. You should look at your
listeners during 95 percent of your speech to maintain a bond of communication
and rapport with them and to monitor their feedback. The question-and-answer period enables listeners to get clarification and
further information. Anticipate what questions might be asked and prepare your
answers accordingly. Try not to be defensive if you are challenged by a listener,
and be prepared to say "I don't know" if you don't have an answer—in
other words, don't try to fake expertise. Practice is a vital part in the success of your speech. You should practice
the entire speech over and over again—until you can deliver it with power and
confidence. |
