Effects of L1 orthography and L1 phonology on L2 english pronunciation

Recent research has revealed the effects of orthography on the pronunciation of consonant durations in the L2 English of L1 Italian speakers (e.g. the [p] in floppy being pronounced as longer than in copy). In this paper we compared this orthographic effect with an orthography-independent effect of L1 phonology, namely VOT. We measured closure durations and VOT for plosives produced by 30 learners of L2 English in Italy, 30 Italian late bilingual speakers of L2 English living in the UK, and 30 native English speakers. While VOT values produced by late bilinguals differed significantly from those produced by learners, closure durations were similar across the two groups. Additionally, L1 Italian VOT values proved that late bilinguals adapted VOT in L2 English by a larger extent than learners. It appears that the effects of orthography on L2 consonant duration can be more resistant to naturalistic L2 exposure than orthography-independent effects of L1 phonology

Orthography-Induced Length Contrasts in the Second Language Phonological Systems of L2 Speakers of English: Evidence from Minimal Pairs

Research shows that the orthographic forms (“spellings”) of second language (L2) words affect speech production in L2 speakers. This study investigated whether English orthographic forms lead L2 speakers to produce English homophonic word pairs as phonological minimal pairs. Targets were 33 orthographic minimal pairs, that is to say homophonic words that would be pronounced as phonological minimal pairs if orthography affects pronunciation. Word pairs contained the same target sound spelled with one letter or two, such as the /n/ in finish and Finnish (both /ˈfɪnɪʃ/ in Standard British English). To test for effects of length and type of L2 exposure, we compared Italian instructed learners of English, Italian-English late bilinguals with lengthy naturalistic exposure, and English natives. A reading-aloud task revealed that Italian speakers of EnglishL2 produce two English homophonic words as a minimal pair distinguished by different consonant or vowel length, for instance producing the target /ˈfɪnɪʃ/ with a short [n] or a long [nː] to reflect the number of consonant letters in the spelling of the words finish and Finnish. Similar effects were found on the pronunciation of vowels, for instance in the orthographic pair scene-seen (both /siːn/). Naturalistic exposure did not reduce orthographic effects, as effects were found both in learners and in late bilinguals living in an English-speaking environment. It appears that the orthographic form of L2 words can result in the establishment of a phonological contrast that does not exist in the target language. Results have implications for models of L2 phonological development

Effects of orthographic forms on second language speech production and phonological awareness, with consideration of speaker-level predictors

Orthographic forms (spellings) can affect pronunciation in a second language (L2); however, it is not known whether the same orthographic form can affect both L2 pronunciation and metalinguistic awareness. To test this, we asked 260 speakers of English-first-language (L1) English speakers, L1 Italian and L2 English sequential bilinguals, and L1 Italian learners of L2 English-to perform word repetition tasks and rhyme judgment tasks for word pairs containing the same consonant or vowel spelled with a letter or a digraph. L1 Italian speakers established a long-short contrast and used consonant and vowel length contrastively in their L2 English, both in production and in an awareness task. This provides evidence for a direct link between the effects of the same orthographic phenomenon on speech production and on metalinguistic awareness. Results were strengthened by combining experimental and qualitative data in the study of orthographic effects. Finally, the results show that proficiency predicts orthographic effects, and that orthographic effect predictors vary in naturalistic and instructed contexts
