It depends on what kind of audience you are facing and the content of your speech. What they care about can be your theme. For example, for those who want to listen to medical care, they say finance, and for those who want to listen to finance, they say life. I'm afraid it won't be attractive after the interaction ... Secondly, there should be real content and data, while for finance and medical care, finance should have specific data, and medical care should be targeted, targeted at the crowd and targeted at the age group. The third is tone and intonation. Since it is a speech, it is necessary to change the speech speed and intonation, and it cannot be directly described, otherwise it will become chanting, and even the wonderful content will become a lullaby.
