Good public speakers are made, not born. Very few speakers can give a stirring speech without preparation and practice. With studying public speaking techniques, you may not become a famous speaker. However, you will be able to get your messages across clearly and completely. Essentially, there are four guidelines to follow in order to deliver a speech effectively.

　　Be lively

　　No one wants to listen to a dull speaker. It doesn't mean you have to tell dozens of jokes to hold an audience's attention. It does mean that your delivery must express your interests and enthusiasm for your topic and your audience. A speaker who has an energetic, lively, active, or assertive style is said to possess dynamism, which is one element establishes a speaker's credibility. Lively delivery can help build the audience's perception of the speaker's credibility.

　　Be natural

　　Good speakers let their unique personalities shine through. They don't try to imitate other speakers.  As you deliver a speech, you'll communicate those same interests and attitudes to the audience through your verbal and nonverbal delivery. Because it isn't as natural to express yourself through public speaking as through conversation, you must be well-prepared. Preparation gives you the confidence that lets you be yourself.

　　Be empathic

　　Good delivery gives meaning to a speaker's message. Through appropriate vocal and non-vocal techniques, you can emphasize ideas or provide pauses that allow the audience to reflect on what has been said. Likewise, using a gesture to indicate an object's size adds clarity to a description.

　　Be appropriate

　　Good delivery is appropriate for the situation, the purpose, and the audience. For example, a speaker presenting a tribute to someone who died would be expected to create a solemn, respectful mood through vocal techniques, posture, and facial expressions, as well as through the words selected.

　　If you meet the above conditions is a successful speaker。

　　自然

　　好的演講者會讓他們自己獨特的個性大方光彩。他們不會試圖模仿其他的演講者。當你發表演講的時候，你會通過言語和非言語的方式來和志同道合的觀眾交流。因為通過公共演講，通過對話來表達自己并不是自然的，你必須有所準備。準備可以給予讓你做自己的信心。

　　情感轉移

　　好的演講可以傳達演講者的信息。通過適當的聲樂和非聲樂技巧，你可以強調思想或著提供停頓來讓觀眾反映所述說的。同樣，使用手勢來表示對象的大小也增加了描述的清晰性。

　　合適的

　　優秀的演講是合乎事宜的，目的和觀眾的。例如，一個紀念逝去的人的演講者會被期望通過聲樂技巧，姿勢，面部表情，以及所選的詞語創造出一個莊嚴的、尊敬的心情。

　　如果你符合以上的條件就可以算是一個成功的演講者。
