Public speaking (also called oratory or oration) is giving speech face to face to live audience. However, due to the evolution of public speaking, it is modernly viewed as any form of speaking (formally and informally) between an audience and the speaker. Traditionally, public speaking was considered to be a part of the art of persuasion. The act can accomplish particular purposes including to inform, to persuade, and to entertain. Additionally, differing methods, structures, and rules can be utilized according to the speaking situation. Public speaking was developed in Rome and Greece. Prominent thinkers from these lands influenced the development and evolutionary history of public speaking. Currently, technology continues to transform the art of public speaking through newly available technology such as videoconferencing, multimedia presentations, and other nontraditional forms.
