We analyse and compare a low dimensional linguistic representation of vowels with high dimensional prototypical vowel templates derived from native Australian English speaker. To simplify the problem, the study is restricted to a group of short and long vowels. In a low dimensional linguistic representation a vowel is represented by the horizontal and vertical position of the part of the tongue involved in the key articulation of a particular vowel, e.g., high or low and front or back. To this is added lip posture, spread or rounded. For a comparison we perform a multidimensional scaling transformation of high dimensional vowel clusters derived from speech samples. We further performed the same analysis on Lebanese and Vietnamese accented English to investigate how differences due to accents impact on such a representation.
