Abstract
The present article explores and analyzes the acoustic aspect of vowel-to-consonant assimilation in Colloquial Persian. To do so, the acoustic variables of intensity, duration, F1, F2, and F3 of the two phonemes are investigated on which assimilation is applied. This research involves the analysis of acoustic properties of each phoneme in a non-assimilated phonetic context in initial, intervocalic, and final position and then these properties will be compared with acoustic properties of the same phonemes in an assimilated phonetic context. In this way, the acoustic variable of assimilated sound whose average value is between the acoustic properties of the two phonemes in assimilated and non-assimilated phonetic context would show the assimilation process. The results of this analysis show a kind of acoustic assimilation in the variables of intensity, duration, F1, F2, and F3 of the two phonemes in question.
