ABSTRACT
The speech wave conveys several kinds of information, which consists principally of linguistic information that indicates the meaning the speaker wishes to impart, individual information representing who is speaking, and emotional information depicting the emotion of the speaker. Human speech production begins with the initial conceptualization of an idea which the speaker wants to convey to a listener. The speaker subsequently converts that idea into a linguistic structure by selecting the appropriate words or phrases which distinctly represent it and then ordering them according to loose or rigid grammatical rules depending upon the speaker- listener relationship. The speech production process involves three subprocesses: source generation, articulation, and radiation. The human vocal organ complex consists of the lungs, trachea, larynx, pharynx, and nasal and oral cavities. The distribution of the vowels extracted from continuous speech generally indicates an overlap between different vowels.
