Even a brief consultation of the existing phonetic and phonological literature demonstrates that several representational systems and schematics have been formulated for the English vowels. Indeed, many authors have discussed these differing systems, including Peter Ladefoged, Daniel Jones, and George L. Trager and Henry L. E. F. Smith. This paper presents and discusses these representational systems, and in general, the comparative examination given here demonstrates that a significant number of major differences exist among these systems. Learning and studying these differences could aid learners in the process of acquiring and understanding English vowels.
