আপনি যদি শিক্ষানবিশ বক্তা হয়ে থাকেন

If you are an apprentice speaker, the first condition for a fluent speech is that the content of the speech should be very simple.
The main goal of any speech is to inform the audience. It is enough to have at least two or one new information.
Heavy speech not only loses the attention of the audience, the speaker loses fluency in it. The speaker must know two aspects.
First you need to check if you can present the whole topic with one or two sentences, which means the comment topic needs to be very informative and objective.
You should not try to give a speech if you do not have a clear idea of what you are going to say.
This will make you a laughing stock to the audience. So at the beginning of the lecture, try to make the content simple, it should be simple, it should not be heavy with a lot of information, it should be explained in a few words and the speaker should have this confidence before listening to the audience, he is fully aware of what he is going to say.
