Determining the sonority scale of Persian phonemes based on an acoustic study and comparing it with Parker's model (2008)

Sonority and its various aspects, in addition to affecting the structure of a syllable can trigger somephonological and morphophonological processes.The foundation of these sonority-based processes is that the sonority scale of all the phonemes should be determined in a hierarchical order.To achieve this primary goal, a sonority hierarchical model of Persian phonemes was proposed according to the theoretical foundations previously clarified about sonority,.Then, all the 23 Persian consonants were used in the onset and coda position of the CVC syllable. The 6 vowels of this language were also used in this syllable.In the next step, all the data were put in carrier sentences, then read and recorded three times by 10 monolingual native Persian speakers.Since according to Parker (2008), there is a direct relationship between intensity and sonority, so the intensity of all phonemes was measured in Praat software (version 6.1.42). Following that, through Pearson's correlation coefficient, the relationship between the intensity and sonority scale proposed in the hypothesis was calculated. In doing so, the calculations were done for individual phonemes and phonemic classes and the results were 0.90 and 0.91 respectively and the hypothesis of the research was statistically attested. Finally the hierarchical sonority model of Persian phonemes was presented.Moreover, the comparison of this model with the model suggested by Parker (2008) showed that it is completely consistent with it, and it can be claimed that Parker's model (2008) is also confirmed in Persian.
