Know your audience:
The most important thing is to know your audience and the nature of the ceremony as there are times when cracking jokes is good whereas there are also times when you need to be serious. Do some research about the people attending the ceremony as this will really help you establish direct contact with your audience.
Write a grasping intro:
Remember, you won’t have much time to lock their attention so give your best shot straight away in the beginning. Starting your speech with facts and figures is an old and boring approach. You may engage your audience with some decent jokes or questions and then tell the objectives of your speech. Make sure your introduction is not too long.
Divide your speech into sections:
To cover all the aspects in minimum time, you should divide your speech in three segments, the beginning, middle and the end. Then divide each segment into further sections. Cover one point in one section and try to follow a theme in each segment.
Follow a pattern:
Your speech must be like a flowing stream which is taking everyone with its flow. Do not break the continuity and make bridges between each segment. However, it does not mean that you need to be a robot. You can hike around but do not lose the main track.
Be exact and direct:
You should not play with words rather it is always better to be direct and exact. For example, saying “I think” instead of saying “It is thought” carries more realism. Write your speech in the active voice.
You should be original and innovative. Do not use sentences that people have heard a hundred times before.
You should make a memorable climax as this is your last chance to leave a long lasting impact.
