Abstract
Public speakers whose primary responsibility is the giving of technical or scientific information need to acquaint themselves with an orderly and consistent design for organizing, supporting, and delivering an oral presentation so that they more effectively engage in dynamic communication with an audience. The elements of such a design are an analysis of audience interest in and knowledge of the topic, the role of speech in presenting highly complex technical or scientific language, and the principles of dynamic communication as they relate to audience perception and retention of information. This guide includes a comprehensive survey of the public speaking situation, suggestions for vocal delivery and scripting, and a checklist of common errors made in presenting factual material.
