All speech is composed of combined individual sound waves that gives speech its particular qualities. Vowel space measurements are usually plotted in charts in which the second formant is plotted against the first formant. For this investigation, the formant values are taken from a computer program that employs a Fourier methodology to analyse the sound signal. This paper presents information about an improved method for vowel space depiction that was created by employing the mathematical integration of formant data. This model produces a more reliable mathematical model of the vowel space. Each vowel formant can be represented by an algebraic equation.
