Prosody plays a prominent role in early language development. However, research on prosody acquisition is still limited and mostly centered on Romance and Germanic languages. The typologically challenging nature of prosody in Persian is reflected in ongoing debates on the nature of stress and intonation. Previous accounts have exclusively focused on the adult prosodic system, and developmental research as well as systematic descriptions of the earlier stages of prosody acquisition are lacking. In this chapter, we describe the early perception of stress and intonation by Persian-learning infants aged between 5 and 9 months. Using eye gaze measures, we demonstrate (i) that Persian-learning infants are sensitive to native contrasts in prominence (like /mɒhi/ [mɒ. ˈhi] “fish” and /mɒh-i/ [ˈmɒ.hi] “any/some month”) and (ii) that Persian-learning infants discriminate native intonation contrasts as those found in the melodic patterns of statements and questions. The results from Persian-learning infants are compared to results available for other languages, such as English, French, and European Portuguese. The implications of the findings from language acquisition to generalizations about the stress and intonation systems of Persian are discussed. Furthermore, the findings from early language acquisition will lay the foundations for assessment in typical development and intervention in prosodic impairments in Persian-learning children.
