The Sound Pattern of English (frequently referred to as SPE) is a work on
phonology (a branch of
linguistics) by
Noam Chomsky and
Morris Halle. It presents a comprehensive view of the phonology of
English, and stands as a landmark both in the field of phonology and in the analysis of the English language. Chomsky and Halle present a view of phonology as a linguistic subsystem, separate from other components of the
grammar, that transforms an
underlying phonemic sequence according to rules and produces as its output the
phonetic form that is uttered by a speaker. The theory fits with the rest of Chomsky's early theories of
language in the sense that it is
transformational; as such it serves as a landmark in Chomsky's theories by adding a clearly articulated theory of phonology to his previous work which focused on
syntax.
