A Comparison of the Extent of F0, F1 and F2 Movements in Native and Non-Native English Vowels: Potential Cues to a Foreign Accent

The present study examined the extent of pitch and formant movement in English vowels produced by Australian and Japanese speakers. In an earlier perception study, stimuli elicited from the same speakers were presented to 19 native English listeners who were asked to identify the native speaker in a forced-choice task. The stimuli - monosyllabic English words presented in pairs - had been controlled such that the vowels by native and non-native speakers were matched for F1, F2 at the midpoint and vowel duration. The results Revealed that native listeners were able to differentiate native from non-native speakers accurately even when acoustic variability was highly controlled. The aim of the present study was to search for residual acoustic cues that the listeners may have used to detect a foreign accent and determine the identity of the speakers. The Australian and Japanese groups differed in F0 and F2 ranges, suggesting a potential contribution of these cues to a foreign accent.
