Public Speaking is giving a speech face to face to a live audience. It comprises various forms of spoken communication skills ranging from imparting a speech.
The only input that goes into public speaking is the speaker, his or her verbal talent, and style of communication, all elements displayed collectively as a package.
Extempore is a speech that is delivered without preparation. The speaker is given a topic on the spot and is given a minute or two to prepare on the same.
The style of delivery of every individual is different from others. Every speaker possesses few unique qualities and has complete freedom to design his or her communication style.
Most forms of public speaking work in a similar fashion. The purpose of the speaker is to convince the audience to agree with the stance of the speaker.
Effective public speaking requires the speaker to deliver so efficiently that at the end the audience stands out thrilled, amazed, and persuaded.
