Investigating the phonological process of consonants’ assimilation in Kalhori Kurdish dialect based on the optimality theory

In this research, the phonological process of consonants' assimilation in Kalhori Kurdish dialect has been analyzed and described in the framework of the optimality theory and various types of consonants' assimilation in this dialect have been analyzed and described.
