Determining the acoustic properties of the sounds of any language is assumed to be the initial step in pedagogical or linguistic studies. No attempt to study Persian vowels' acoustic properties has been reported yet according to our knowledge. With the help of spectrographic and F1 and F2 comparison of Persian vowels this paper attempts to do a computer-based acoustic analysis of Persian vowels, and provides a digitized and authentic chart of Persian vowels. As a result, based on the formant values, a vowel space plot of Persian vowels was developed. Also, the theory of efficiency of these three vowels / i, a, u / as the major means of communication in the majority of languages of the world is supported by the results. Furthermore, the analysis of distributional occurrence of these vowels in the vowels space and their relative distance from one another suggest that the pressure to form pattern has made Persian language to develop a vowel system which could be described in a triangular auditory space. In addition to these cornering vowels, Persian language has developed three other intermediate vowels / e,?,o / to create a symmetrically distributed vowel system to cater the communicative needs of the language users. In general, in a descriptive method the acoustic properties of Persian vowels / i, e, ?, a, o, u / are examined and illustrated in this paper.
