The most difficult thing in public speaking is keeping the audiences in attention - means listening instead of walking around or doing something else. Here are some tips to handle the problem.

1. Show how your ideas relate to the problems and interests of your listeners before launching into your own interests. A good speaker usually catches the audiences' interests by providing a continual variety of stimuli, such as by varying the input of ideas and giving them continual change in the pauses, speed and volume of his or her voice.

2. Enthuse yourself about the subject because there is much evidence that the speaker's attitude and psychological state can affect the audience's reception of his message.

3. Use humor. It can be by telling a joke, funny story or personal experience related to the meeting topic. Or open your presentation with an amusing slide, famous quote or cartoon.

4. Ask a question early in the meeting, but tell audiences that you do not want an answer until the end. To encourage active listening, offer a small prize for the first correct answer.

5. Show and tell. Use visuals, like PowerPoint graphics to get your point across. In the next occasion, use a variety of visual tactics to keep things fresh.

6. Turn your speech into a discussion to confirm the effectiveness of what you are saying or offering.

7. The most important thing is speak in a clear and comprehensible voice with an enthusiastic tone.

8. Another thing you need to consider is the sheer length of time the audiences are expected to listen. Based on a research by MacManaway, twenty to thirty minutes was the maximum length of time they could listen to a speaker without wandering. This means that the speaker should provide pauses and increasing variety, as the talk gets longer.
