The information exchange between the speaker and the audience is realized through the speech language. Without language, speech would cease to exist. Speech language is a colorful kingdom: there are both internal languages that feel beauty with heart and oral languages that feel beauty with sound; It is not only the body language of tangible beauty and sense of purpose, but also the prop language of Wu Mei and touching; There are both skillful poetry recitation and flexible use of famous sayings and aphorisms; There are both cadences and priorities; There are both high notes and low notes; There are both serious styles and humorous humor. A successful speech is a comprehensive use of these languages in a timely, moderate, appropriate and flexible manner. The comprehensive use of multiple languages is to make the audience accept various phonetic stimuli, thus mobilizing the enthusiasm of the audience to "listen", strengthening the theme of the speech, leaving a deep impression on the audience and serving the success of the speech. It is difficult to succeed in speaking with poor and boring language and single boring vocabulary.
