This edited volume investigates the role of phonetics and phonology in psycholinguistics. Speaking and understanding spoken language both engage phonological and phonetic knowledge. There are detailed models of phonological and phonetic encoding in language production and there are equally refined models of phonetic and phonological processing in language comprehension. However, since most psycholinguists work on either language production or comprehension, the relationship between the two has received surprisingly little attention. Prominent researchers in various areas of psycholinguistics were invited to discuss this relationship focusing on the phonological and phonetic components.
