There are 5 things you have to keep in mind while giving speech.

Who is listening to your speech - your audience?

How to start? - The beginning of your speech - your introduction

How to proceed and what to do next?

What are the highlights of your message? - The climax

How to close the speech? What to do afterwards?

Savion.

what you said the 5 things is superb..
can you make it much clear by giving brief description about those
because i have to give speech in the next month so you would much appreciate...

Who's your target audience ... men? women? youth? age 20+?, business people?, etc...
Your introduction should almost be a summary, except at the beginning. Why are they listening to your speech? Why will this be important in their lives? etc...
Then comes the details ... keep to point & remember your audience.
Sharing experiences or referencing is always good.
Use any displays, slide-shows, etc to keep it interesting
Closing is a quick overview again. Make it stand out when your presentation is over.
Good Luck with your speech
