In public speaking, several persuasive tips or techniques include emphasizing main points through vocal sounds rising and falling, using gestures to express an idea, asserting judgments about each finding, pre-empting common objectives, establishing common ground, using emotion and creating new approaches for the audience. Utilizing these tips and techniques in persuasive public speaking can help to create a persuasive argument and to influence the audience to agree with the speaker's argument.
Establishing common ground is important for persuasive speeches because it attracts the audience members to the argument. They are more likely to agree with the speaker when they view the speaker as a person of integrity, and will help align the audience with the speaker even if the speaker has differing or alternative views.
This also includes pre-empting common objections by thinking about what the audience may have a problem with, or what their concerns may be ahead of time, and then addressing them in the speech. The speaker should provide new approaches to these concerns or problems.
Using emotion is also vital in creating a powerful persuasive speech. Emotion is the key to changing people's beliefs when paired with powerful facts and data along with new approaches to commonly held problems or concerns. Emotional language can help to persuade and influence. This can often be done by adding personal details and issues from one's own life in order to help build a strong emotional component within the speech.
