Build in Redundancy
Audience retention is determined by a number of factors including listeners’ interest, knowledge, physical and emotional state, level of stress, background, and other competing demands (19). One way to help your audience remember the content of your speech is by repetition (24). There are three ways to incorporate repetition into your speech. The first form repetition involves restating your main points in your introduction, body and conclusion. When you do this, you will restate your points using different language—not repeat the points word for word. The second form of repetition is where a word or a phrase is repeated in a poetic way, either throughout the speech or at a critical point in the speech. One example of this would be Abraham Lincoln’s “government of the people, by the people, for the people.” Another example can be found in Sojourner Truth’s speech, delivered in 1851 at a women’s rights convention.
… That man over there says that women need to be helped into carriages, and lifted over ditches, and to have the best place everywhere. Nobody ever helps me into carriages, or over mud-puddles, or gives me any best place! And ain't I a woman? Look at me! Look at my arm! I have ploughed and planted, and gathered into barns, and no man could head me! And ain't I a woman? I could work as much and eat as much as a man—when I could get it—and bear the lash as well! And ain't I a woman? I have borne thirteen children, and seen most all sold off to slavery, and when I cried out with my mother's grief, none but Jesus heard me! And ain't I a woman?
The final way to use repetition in your speech is through nonverbal communication. When you say the word “four” and you hold up four fingers, or when you verbally agree with a point and nod your head at the same time, you are reinforcing the idea verbally and nonverbally.
