I need to know some answers regarding speech communication

[angelico]

well, i'm a student, and we just had an assignment regarding speech communication. our instructor asked us to search about three functions of speech communication, it's nature, essential characteristics, and two forms of communication. well, I tried googling about it, but the topics are all mixed up. i hope that you can answer my questions, it will really help me a lot. p.s. sorry for my poor english. :)
