Phonologically constrained variability in L1 and L2 production and perception

One of the core goals in phonetics and phonology is to understand the precise relationship between variable phonetic details and phonological representations. This special issue of 'Phonetica' comprises papers offering novel insights, each providing a substantial expansion upon a selected oral presentation given at Phonetics and Phonology in Iberia (PaPI; Lisbon 2013). Chapters present new data on and analyses of currently debated topics such as the nature of phonological representations, the principles of phonetic variation and sound change, and models of phonetic and phonological aspects of second language (L2) acquisition. The new material and insights brought forth in this topic issue make it indispensable reading for phonologists and phoneticians as well as specialists in language and cognition in general.
