Communication is a vital key in this new century. It gives an edge to keep abreast with the fast pace of the times. Public speaking definitely works towards this goal. The diversity of opinions today, which are often controversial, has increased the need for public speaking. People need to voice out their views to function well in society. For some four thousand years, public speaking has been the key in building and keeping a democratic society and way of life. Its influences are vast and affect almost all aspects of life, such as the way we think or act. It is also used in court proceedings, in congress, and even in the plain setting of a classroom.

Speaking in public can sometimes be a real challenge, if not a source of embarrassment; not only to normal people, but even to persons of high rank such as scholars, doctors, artists and entrepreneurs. They may have hesitations in facing an audience, often accompanied by sweaty palms, stuttering, and the tip-of-the-tongue phenomenon. These dilemmas often cause untold problems to the speaker (especially in self-expression) and unpleasant effects to the audience.
