Before preparing, why even before accepting for delivering a speech, please understand the purpose, occasion and audience. Your speech should fit in well for the occasion, purpose and more so audience. If any mistake is done in this, you can’t be comfortable, successful and happy in delivering your speech.
If you are one among many speakers in a function you have to take extra care. Usually the first few speakers will take more than the prescribed time (many chair persons are not strict) and time compression will be requested for the fag end speakers (closing time may not be compressed since transport for the audience might be a constraint or lunch / dinner would become cold.)
Also it is not enough if you go with hectic preparation. You should listen to you previous speakers attentively till you get your turn. Relate your speech to some of the points spoken by the previous speakers. If you do not agree to their points doesn’t attack the person point black. You should give respect to the individual and intelligently inject your view by giving reasons and examples in a polished way. Never create scenes.
As far as the types of speeches concerned we can categorize them into four types.
1. Motivating speech
2. Informative or knowledge sharing speech
3. Speech for recognition or honor
4. Farewell speech
