Frequency of compression process in Bybee Approach plays a vital role between different characters in dialogues of Persian films. In various historical periods, considering her social status, “woman” less likely has used non-standard Persian language compared to “man”. The main issue of this study is about the frequency of compression process in Bybee approach between two male and female sexes in Persian Movies. Which one of Persian language’s elements has been shown more in studied movies in opinion of Bybee? How the language can challenge the system of feminine and masculine relationships in performances? What is the cultural function of identity in this field? This study was conducted to analyze the phonology of phonetic changes caused by compression in Persian language within two different cultural and social fields. Such differentiation is well revealed in dialogues of movies associated with abovementioned historical periods. In fact, this study indicates that compression has a cultural origin as a social issue and such cultural origin that indicates itself in linguistic or discursive styles of individuals with different social classes. Moreover, study of compressed forms is not just limited to making decision about summarization so that the differences between compressed forms are not just structurally a morphological phenomenon; sometimes, it depends on some functional and social considerations such as gender type.
