If you are very much in comfort with it, use humor. Just check it first if it fits, serving as a breaker between sections or emphasizing a certain point. A funny and great line, or a comment that is irreverent can help liven up the presentation that you have and will help people to remember the things you have said. Of course any joke must be related to the topic that you have in some way. If you are not sure about something, you could also use a humorous photo or cartoon (with the permission of the photographer or illustrator, of course) in your slides.

Aside from making jokes or humor in your speech, you could improve your public speaking with these other tips.

- You should be able to grab your listeners' attention even right at the start. That is why it is important that you start correct – confident posture, eloquent speaking style, controlled voice tonality and impact, and a nice, well-thought speech from you.

- The information in your message should be organized clearly and logically, making it easy for your listeners to follow what you are trying to say. Keep things easy and simple. Divide the information into smaller blocks and work from there. Highlight the points that you want your audience to remember.

- Your most crucial point should be the conclusion, bringing the speech to a close. The conclusion sets the tone of the speech, and lets the listeners think about and ponder on the things you have just said. Literary devices, such as quotes, stories, rhetorical questions, or surprising facts, can be used for concluding a speech, although of course, these devices should relate well to the topic of your speech.

- Deliver the conclusion that you have clearly and slowly. Keep eye contact with your listeners as you speak. Smile at them, thanking them for the time that they have given you.

- You should remember all these tips and in due time, you would be surprised to see how these techniques have helped you in your future speaking presentations. Your listeners will eventually understand the information you have given them and respect you for your ability in delivering that information.
