A、Ask the audience many questions. B、Summarize the material which is familiar to the listeners. C、Give detailed facts and number

W: As a well-known public speaker, can you give us some suggestions on how to deliver a good speech?
M: To begin with, you should ask yourself a question, that is, what does your audience need and want? It’s better to question yourself before the speech.
W: Why do we need to know their needs and wants?
M: If you are a public speaker, it is absolutely essential to know how to capture and maintain the interest of your audience, which means you have to know what they want to know and what they want to hear.
W: You mean we should pay special attention to the content of the speech, right?
M: Yes. If you elaborate on facts and figures that everyone is already familiar with, then it is quite possible that you will actually lose the attention of those who are listening to your presentation.
W: What should we do then?
M: Many successful speakers will summarize that part or add some different viewpoints to it. This is a good way to increase their level of understanding of the topic. If your audience cannot follow your speech, it’s quite possible that they’ll leave or doze off.
W: How about body language? I see many speakers use a lot of hand gestures.
M: Not only hand gestures, but also facial expression, body movement and even voice changes. It is always important to remember that sometimes, how you say something will have a larger impact than what you say.
