An Acoustic Comparison Between American English and Australian English Vowels

Kimiko Tsukada

University of Alabama at Birmingham, USA

Five vowels /i, E, ć, A(or 6), u/ in isolated /CVC/ words produced by 7 American English (AmE) and 6 Australian English (AusE) talkers were examined with a view to documenting acoustic-phonetic similarities and differences between the two accent types. The effect of Accent was significant on all vowels for at least one of the first two formants. The AusE vowel space was much more compressed relative to the AmE vowel space. In both varieties, however, withincategory clustering was quite good, suggesting that these talkers’ productions were fairly consistent within their respective vowel systems. Although the two groups differed considerably in vowel quality, they were quite similar in vowel duration.
