Production of Vowel Reduction by Mexican Learners of English as L2 and Russian as L3

Abstract

AbstractIn this study, we examined to what extent cross-linguistic influence is observed in the production of unstressed vowels in Mexican learners of L2 English and L3 Russian. Phonological spectral vowel reduction is a widespread process present in both English and Russian, but not in Spanish. In total, 18 Mexican learners, six American speakers, five Russian speakers and six Mexican speakers performed a delayed word repetition task and a sentence completion task. Euclidean distances and temporal values were measured to assess vowel reduction in 1,192 tokens. Mexican learners showed hybrid values of vowel reduction in both foreign languages: while they tended to use quality cues in the case of the L2, they relied on duration cues in the case of the L3. Our results do not show any direct evidence of cross-linguistic influence of temporal values or vowel quality from the L1 or the L2 on the L3. We examine these findings in light of similar studies and current L3 acquisition models.
