first, speech can promote the growth of speakers. Only those who are willing and not afraid of hardships can climb the peak and take off the laurel and put it on their heads. Although it is only a moment to wear it on your head, you can imagine how many times the speaker has achieved it before and after this. Because, the speaker is not born, but is caused by the practice of speech. Hard and multifaceted efforts are the only way for a speaker to become a speaker.

Second, speeches can cultivate good interpersonal relationships and noble sentiments. Modern society is a society in which people have increasingly close contacts, and it is a civilized society in which information is widely exchanged and disseminated. A speaker should not only have a glib mouth and elegant manners on the stage, but also set an example in his words and deeds off the stage. Their speech should be modest and elegant, and their manners should be decent and generous. Such words and deeds are not only conducive to creating a peaceful atmosphere, but also conducive to people's exchanges.

Third, speeches have the function of continuous self-improvement. A person with high moral character, profound knowledge and superb skills can't fully develop all his intelligence if he is not good at talking and doesn't express his ideas. Speech is the most advanced, perfect and aesthetic expression in human oral language.

In addition, speech needs comprehensive knowledge, which requires not only the theory and experience of oratory itself, but also the basic theories and knowledge of philosophy, aesthetics, logic, psychology, pedagogy, linguistics and writing. If we learn, understand and master the art of speech and practice it, we can increase our talents, broaden our horizons, cultivate our sentiments, accumulate knowledge, strengthen our self-cultivation, exercise our eloquence, cultivate our temperament, show our image, expand our popularity and improve the success rate of our career.
