The nature of an overall system for English was controversial: the analysis in was popular amongst American linguists for a time (in the face of criticism, particularly from Hans Kurath); James Sledd put forth his own diaphonemic system that accommodated Southern American English; both and modified the scheme of "The Sound Pattern of English" by focusing on the diaphoneme, believing that it could address neutralizations better than structuralist approaches; and "The Pronunciation of English in the Atlantic States " ("PEAS") by Kurath and McDavid combined several dialects into one system transcribed in the IPA. More recently, "The Cambridge Grammar of the English Language" makes use of a diaphonemic transcription of Standard English so that examples can be expressed concisely without favoring any particular accent.
