Abstract

Speech is unique mode of communication among humans. Speech is a complex method of
communication systems when compared with other methods. As humans, we also use non-speech, which is nonverbal communication to convey information. Nonverbal communication not only accentuates on the meaning of
words, but also provides information such as, what kind of emotional state the person is in. non-verbal
communication provided a higher level of information, which includes characteristics of a human voice and in
this paper we will show how we can use these characteristics to identify person.
