In my thesis I have used both computational and experimental methods in order to investigate the nature of syllabification in languages generally and in Persian particularly. Traditionally, it has been argued that phonological constraints (abstract rules in our mind) account for phonological patterns. Although recent studies on the role of articulatory/perceptual phonetic factors in phonological phenomena have provided consistent explanations for phonetically-based phonology, they have rarely used data driven approaches to provide statistical evidence in support of their hypothesis. Here I’m going to introduce the related background notions and my efforts to shed some statistical light on this long debated problem in theoretical and experimental linguistics.
