     The Importance of Setting Speech Goals

     A speech is a wonderful opportunity to inform, persuade or entertain. The best speeches often take

on a combination of all three of these components. However, before you can go about the writing of a

great speech, it is important to set goals. Goals keep you, your speech and your audience focused.

     What a goal is

     In the context of a speech, a goal is the purpose of the speech, and what it hopes to accomplish. For

example, the goal of a eulogy (颂歌) might be to celebrate the life of a loved one. The goal of a speech

at a political gathering would be to inform the crowd about the political position of a candidate and

persuade them to vote and campaign for the candidate in question.

     Why a goal is important

     Without a goal, a speech is without direction. The goal informs the structure and content of the speech. For example, if a speech's goal is to convince people that smoking is bad for them, the speech will be

structured with persuasive arguments to back up the goal. A speech with a goal of informing the audience will keep the information fair and factual.

     A goal is incredibly important to the speech's ability to connect with an audience. If the speaker is

unaware of the goal of the speech, the audience will likely be unaware as well. This severely reduces the

effectiveness of the message.

     Aside from informing the audience of the content and structure, a speech's goal drives the speaker to

greater heights. If a speaker is asked to speak on a specific subject, but never establishes the goal, they

won't know where to start in the research, organizing and writing of the speech.

___________________________________

     If you have been charged with (被委以) delivering a speech, establishing a goal can seem difficult at

first. There are several things to take into consideration. First, think about who you will be speaking to.

The demographic (人口统计) of your audience will likely determine whether you will be able to persuade them, or whether they will be able to sit through. Second, think about the topic itself. If the topic is

something controversial(有争议的), it may be worth your while to consider an informative approach to

present both sides of the issue. Finally, consider your resources. A speech with an informative or

persuasive goal usually requires a great deal of research, and sometimes takes more time to write.
