For example, Selkirk (2011, and others) proposes that prosodic structure is constructed by a process of matching, although imperfectly, prosodic constituents to syntactic constituents. Kahnemuyipour (2009) demonstrates, using evidence from several languages, how information structure can be represented in the transfer from syntax to phonology, arguing that transfer can only be uni-directional, from syntax to phonology.
Oltra-Massuet and Arregi (2005) argue that the metrical structure, as well, makes reference to hierarchical syntactic structure in Spanish. The extent of the interaction between the syntax and phonology at the interface is a matter of current debate.
