Read through your script or outline of the speech and look for any material that might be considered sexist, biased, patronizing, prejudiced, insulting, or profane and leave it out. No matter how similar your audience may look to you, it is still diverse. You want to make sure that material offensive to any segment is omitted. If you are unsure about any material, leave it out. Fifth, leave out complicated sentences and words.
Oral speech is different from writing.
In written script, you can have long complicated sentences and the reader can easily follow your train of thought. In speaking, however, you want to have succinct sentences. Words for the ear are short, active, alive, and instantly clear. Patrick Henry, Franklin D. Roosevelt, and Martin Luther King, Jr., are remembered for their brief, incisive words. Don t put your best ideas or evidence early in the speech.
