Abstract:
This study examined how much information is needed for listeners to detect a foreign accent. Two factors were considered regarding the amount of information: stimulus length and L1 phonotactics. Four Korean-English bilinguals and two native speakers of American English produced different lengths, but still short stimuli: the vowel /ɑ/, monosyllabic and disyllabic English words. The monosyllabic corpus, in particular, included the stimuli having both natural (i.e., CV) and unnatural syllable structures (i.e., CCV, CVC, and CCVC) as well as various segments in terms of Korean phonotatics. After being presented with a stimulus, eight native listeners were asked to judge whether the speaker of the stimulus was a native or a non-native speakers of American English. The examination of d′ value indicates that all the listeners detected a foreign accent from hearing the monosyllabic and disyllabic stimuli, but only some listeners did from hearing the vowel /ɑ/. Furthermore, the listeners detected a foreign accent more often from the stimuli having the coda segment. Lastly, d′ values for the stimuli having /l/ were lower than those for other stimuli. All these suggest that listeners may not need much information to detect a foreign accent, which, in turn, is closely related to L1 phonotactics.
