Aquisition of stress-shift in English by speakers of Brazilian Portuguese

Abstract

By addressing the acquisition of the English stress-shift rule by speakers of Brazilian Portuguese, this article sheds more light on the debate about the influence of first language and formal instruction on the acquisition of a second language. We carried out an experiment in which 37 native and non-native English speakers were asked to pronounce the same words as single words, in stress clash and non-stress clash contexts in order to observe the productivity of this phenomenon. The results show that stress shift occurs in similar proportions in contexts with and without stress clash and that productivity of the phenomenon among the advanced-level learners was very similar to that of the native speakers. We also found that words ending in an obstruent do not favor the application of the rule, whereas words ending in long vowels or nasals do. These findings show that syllable structure and the segmental inventory of the first language affect the results in the target language.
