In public speaking, as in any form of communication, there are five basic elements, often expressed as "who is saying what to whom using what medium with what effects?" The purpose of public speaking can range from simply transmitting information, to motivating people to act, to simply telling a story.
Good orators should be able to change the emotions of their listeners, not just inform them. Public speaking can also be considered a discourse community. Interpersonal communication and public speaking have several components that embrace such things as motivational speaking, leadership/personal development, business, customer service, large group communication, and mass communication.
Public speaking can be a powerful tool to use for purposes such as motivation, influence, persuasion, informing, translation, or simply entertaining. A confident speaker is more likely to use this as excitement and create effective speech thus increasing their overall ethos.
Effective public speaking can be developed by joining a club such as Rostrum, Toastmasters International, Association of Speakers Clubs (ASC), Speaking Circles or POWERtalk International in which members are assigned exercises to improve their speaking skills. Members learn by observation and practice, and hone their skills by listening to constructive suggestions followed by new public speaking exercises. These include:
- The use of gestures
- Control of the voice (inflection)
- Vocabulary, register, word choice
- Speaking notes, pitches
- Using humor
- Developing a relationship with the audience
The new millennium has seen a notable increase in the number of training solutions offered in the form of video and on-line courses. Video can provide significant training potential by revealing to the student actual examples of behaviors to emulate in addition to verbal knowledge transfer. There are also numerous agencies who offer one to one training in the delivery of a speech.
The objectives of a public speaker's presentation can range from simply transmitting information, to motivating people to act, to simply telling a story. Professional public speakers often engage in ongoing training and education to refine their craft. This may include seeking guidance to improve their speaking skills"such as learning better storytelling techniques, for example, or learning how to effectively use humor as a communication tool"as well as continuous research in their topic area of focus.
People who speak publicly in a professional capacity are paid a speaking fee. Professional public speakers may include ex-politicians, sports stars and other public figures. In the case of high profile personalities, the sum can be extraordinary.
The common fear of public speaking is called glossophobia (or, informally, "stage fright").
Public speaking and oration are sometimes considered some of the most importantly valued skills that an individual can possess. This skill can be used for almost anything. Most great speakers have a natural ability to display the skills and effectiveness that can help to engage and move an audience for whatever purpose. Language and rhetoric use are among two of the most important aspects of public speaking and interpersonal communication. Having knowledge and understanding of the use and purpose of communication can help to make a more effective speaker communicate their message in an effectual way.
Leaders such as Martin Luther King, Jr., Sukarno, and Mao Zedong are notable examples of effective orators who used oratory to have a significant impact on society. The speeches of politicians are often widely analysed by both their supporters and detractors.
Rostrums hold papers for speakers. Public speakers may use audience response systems. For large assemblies, the speaker will usually speak with the aid of a public address system or microphone and loudspeaker.
