Hello, PPT should not speak too fast, otherwise it will give people a sense of embarrassment and self-confidence. The normal speed is 150 words per minute. Don't keep explaining the content. It is a good introduction to say that PPT can control the speed. It's best to take off the manuscript and don't read it, otherwise it will be very lifeless. Of course, you can consider getting a manuscript a few times before to avoid forgetting words. Be fully familiar with PPT content, allocate time in advance, which parts are important and which parts can be skipped, and even if you don't look at PPT, you basically know what the next page is about. The other is the auxiliary skills of explanation. When you talk about PPT, you should insert some content other than PPT, and there is the coordination of gestures and actions, which has a lot to do with the theme and scene. Finally, actual combat. Except for a few gifted scholars, most of the speeches are based on real speeches. No matter how prepared the audience is, there will be many unexpected situations in actual combat. Relax your mind and control your speed. If you talk more, you will always make progress.
