Public speaking is an oral presentation in which a speaker addresses an audience , and until the 20th century, public speakers were usually referred to as orators and their discourses as orations.

A century ago, in his “Handbook of Public Speaking,” John Dolman observed that public speaking is significantly different from a theatrical performance in that it is “not a conventionalized imitation of life, but life itself, a natural function of life, a real human being in real communication with his fellows; and it is best when it is most real.”
Unlike its predecessor oration, public speaking involves an interplay of not only body language and recitation, but on conversation , delivery and feedback . Public speaking today is more about the audience’s reaction and participation than an orations’ technical correctness.
