摘要：This study aims to look into multilinguals’ transfer of graphemic and phoneticphonological patterns during vowel production, taken the role of proficiency in this process. For that purpose, 5 male multilingual speakers of Brazilian Portuguese (L1), Spanish (L2) and English (L3) participated in the study. Their proficiency levels were assessed by validated tests, and they were found to be advanced in Spanish (L2) and intermediate in English (L3). The participants also took part in three reading aloud tasks, one in each language. In each task, they were asked to read carrier sentences (say word), in which the words were high frequency. The participants’ vowels were measured – F1, F2, and duration values – in the software Praat. The vowels produced by the multilingual participants in each language were compared, considering their orthographic and phonetic-phonological similarities. The findings are discussed in the perspective of the Dynamic Systems Theory.
