摘要：The article presents a new purpose, starting by defining suprasegmental elements, in which the study of the accent is included, and also inserting it simultaneously between two criteria that have been postulated as heterogeneous.It presents the natural gerative phonology model, which seeks a major “linguistic realism”, explaining accent through a morphophonemic process and evaluating it in a less mathematical way than the transformational one.Chomsky/Halle model seeks a great formal simplicityin the formulation of the rules, making use of some devices in dealing with exceptions.The article includes some criticism to that analysis, in whichBotha (1971) discusses the value of those devices with no phonetical usecreated to “produce expected effects” in an “ad hoc” way.
