Oratory is a linguistic communication activity that has never been without its presence since ancient times. In ancient Greece, for example, every citizen had the right to vote, so politicians often needed, with their excellent oratory skills, to persuade the public and win their support.

As in ancient times, oratory is now valued by the people. Wherever we are, in whatever capacity, we have all experienced public speaking and often encountered the problems of: being nervous when we get on stage, fear of forgetting the words, fear of saying the wrong thing if there are too many people on stage, and so on. Then we can do some advance preparation.

The first rule, clear face of the crowd and expression content

For the speaker, the first thing to do is to clarify whether the audience is students or product enthusiasts or company leaders, and the content of the speech should be clear; in order to decide how your words, language and body can better interact with the listener.

The second rule, other influences and graphics in PPT design

Don't limit your presentation to what the PPT offers; using some external influences and graphics (including video) can enhance variety and visual appeal to the audience. Sometimes adding a few short video clips to a presentation can help to create humour, convey the message effectively and reduce the feeling of congestion.

The third rule, strong material support

This is also an effective way to prevent nervousness. In a way, the ease of use of the PPT is also its Achilles' heel. While it can be used to emotionally create compelling slides and graphics, you need to know that the PPT does not stand alone.

Audiences don't just come to see the images on the screen, they come to hear your presentation. You need to build a strong set of PPT materials, but also ensure that your verbal comments are equally compelling; remember that the purpose of the slides is to support the verbal presentation.

Rule number four, get to the venue as early as possible

Don't wait until the audience is ready before you are slow to set up the projector and slides. Mention that you have arrived at the venue to familiarise yourself with the scene, check your computer, PPT and projection equipment etc. to ensure that nothing unusual happens and that it helps to take the edge off.

Rule number five, grasp PPT production and presentation restrictions

If the presentation does not specifically state that you are to speak for an hour or more, remember this rule. That is, a PPT production should not exceed 10 slides, the total length of the presentation should not exceed 20 minutes, and the slides should be larger than 30-point font. You must be able to convey the essence of your presentation to the audience in a limited time, with fewer slides and concise language; to be considered a great presentation.

A great speaker must have accumulated a wealth of life experience and studied the culture without stopping and practised relentlessly. In the process, the speaker then grows tremendously, increasing his or her self-confidence, expanding his or her learning and improving his or her presentation skills.
