The role of phonetic detail within the language system and its interplay with other kinds of linguistic information represent a hotly debated territory. In the current volume, different types of phonetic nuances are examined with a particular focus on their relation to phonological, morphological, and semantic/pragmatic phenomena. These three interfaces – the phonetic-phonological, the phonetic-morphological, and the phonetic-semantic/pragmatic one – are investigated from a variety of angles and by consistently taking the rapport between phonetics and phonology into consideration. In doing so, we provide an up-to-date picture of research dealing with the interaction of distinct linguistic areas, and also discuss the question if and when phonology is needed to mediate between phonetics and other linguistic domains.
