Do the following to put you at ease when delivering a speech. Your speech needs a beginning, middle, and end. End your speech on a strong note by asking a question, providing a quote, tell a story or leave them laughing. Stories are out there - everywhere. Find them in the stores, at restaurants, on the airplane, at home.
People retain information better when hearing a story.
Practice your speech out loud. Also do this when giving a program to a live audience. Practice pausing before and after important points. Don't be afraid to leave open space. The use of silence is a key requirement to becoming an effective speaker.
