is a theoretical component of Coltheart's dual-route reading model that refers to using spelling-to-sound correspondences to convert a written word (i.e. orthography) into a spoken word (i.e. phonology). In other words, it is the route by which letters are linked to their sounds and the sounds are assembled into a whole word pronunciation. It complements the lexical route where the whole word is recognized and linked to its sound.
