Stress in Persian

This research has been carried out in the framework of Auto segmental-metrical (AM) phonology to study the stress in Persian. Two types of abstract and concrete prominences were distinguished in which the first one refers to the stress and the second one refers to the pitch accent. Stress is assumed to be a lexical property of the lexemes, but pitch accent is assumed to be an intonational element; therefore, contrary to stress, pitch accent in not fixed and predictable. Pitch accents could appear only on the lexically stressed syllables, if the context necessitates. Using the interface between phonology and morphology, it was concluded that all classes of lexemes are stressed on their final syllables in Persian; of course some grammatical morphemes are exceptions. Stress in inflected forms of words was formalized in which inflectional morphemes are stressed and receive the stress of the word, but clitics are unstressed and do not change the position of word stress if added to the stem. The results of this study could be used in linguistic studies and in different branches of Natural Language Processing (NLP) as well.
