Linguistic Dimensions of Accentedness, Comprehensibility and Intelligibility: Exploring Listener Effects in American, Moroccan, Turkmen and Chinese Varieties of English

Abstract The present study examines accentedness, comprehensibility, and intelligibility of American English, Moroccan English, Turkmen English, and Chinese English, from the perspectives of three groups of listeners: native speakers of English and Chinese speakers of English with or without international experiences. Of the 145 listeners, 38 had face-to-face interviews. These listener groups were asked to listen to the recordings of the four English varieties and fill in a cloze test. Results indicated that the three listener groups differed significantly in rating comprehensibility of American English, Moroccan English and Chinese English but they did not give Turkmen English statistically different ratings; there were no significant differences in accentedness ratings except for Chinese English; and there were significant differences in the intelligibility scores of the four English varieties. In addition, with respect to seven linguistic variables—speed, clarity, intonation, smoothness and fluency, vocal intensity, pause, vocabulary and grammar, there were significant differences in three listener groups’ rating of six variables in American English except the one of “speed”. By contrast, Chinese English received significantly different ratings only in “proper speed”. No differences were found in the ratings for Moroccan English and Turkmen English. Finally, unlike Chinese listeners without international experiences, native listeners and Chinese listeners with international experiences shared some similarities in correlations between the ratings of accentedness and comprehensibility and those of linguistic variables on Moroccan English, Turkmen English, and Chinese English. However, the results for American English from Chinese listeners without international experiences and native listeners seemed to be more alike. Linguistic variables correlating with accentedness and comprehensibility of American English showed a mixed profile. Qualitative data provided more variant elaborations on the pronunciations and language uses of the speakers.
