One of the most interesting features of language contact situations involves the appearance of systematic patterns that are not manifested in either of the two languages in contact. A full analysis of such patterns may require constraint rankings that differ from those of both the native and the target languages. I examine possible sources of these constraint rankings with respect to the devoicing of final obstruents in learners whose native language contains either no final consonants or no final obstruents, and whose target language contains both voiced and voiceless final obstruents. I conclude that the interlanguage ranking follows from the frequency of different input structures, given the assumption that constraint rankings are stochastic (Boersma & Hayes, 2001), and that final devoicing is an effect of positional markedness constraints. I then consider possible alternative explanations of interlanguage final devoicing: as a reflection of native language rankings of positional faithfulness constraints; as an effect of perceptual filtering; and/or as a function of articulatory difficulty of sustaining voicing in final position.
