Instrumental Analysis of English Vowels Produced by Male and Female Zilfaawi Arabic Speakers

Abstract

Arab and non-Arab English as a foreign language (EFL) students continue to have difficulty pronouncing English vowels accurately. To examine this, our study analyzes how male and female Saudi EFL students pronounce English monophthongs when compared to native speakers assessed in previous research. Gender-related variations between male and female Arab English speakers are also explored. Formant frequencies (F1 and F2) are employed to evaluate vowel quality, with vowel duration measured to investigate vowel length. Learners’ pronunciations of English words containing vowels of interest are used to collect data. Five male and five female EFL learners produced English monophthongs in the /hVd/ context. We then compare the results with previous data on native English speakers and conduct acoustic analysis. Regarding duration, male non-native English speakers’ data are compared with previous results for male native speakers, revealing that the vowels of Saudi learners are shorter than those of native English speakers, and those of non-native men are longer than those of non-native women. Moreover, the low vowels produced by Saudi and native men are longer than their non-low vowels. Regarding vowel quality, men produce lower vowels than native speakers. Women, however, produce lower and more front vowels than native women. Statistically, this study reveals significant differences between male and female Saudi EFL learners in producing English vowels. Saudi men’s vowel space is more centralized than Saudi women’s space. Both men and women overlap low vowels. Saudi learners’ mispronunciations of English vowels indicate that L1 interference is not the only cause of mispronunciations.
