  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 non-verbal 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.
