The Effect of Indian Contact and Glaswegian Contact on the Phonetic Backward Transfer of Glaswegian English (L2) on Hindi and Indian English (L1)

This study examined phonetic backward transfer in 'Glaswasians', the ethnolinguistic minority of first-generation bilingual immigrant Indians in Glasgow (Scotland), who present a situation of contact between their native languages of Hindi and Indian English (L1s) and the dominant host language and dialect, Glaswegian English (L2). This was examined in relation to the Revised Speech Learning Model (SLM-r) and Speech Accommodation Framework. These predict that the migrants' L1 sound categories can either shift to become more Glaswegian-like ('assimilation' or 'convergence') or exaggeratedly Indian-like ('dissimilation' or 'divergence') or remain unchanged. The effect of Indian and Glaswegian Contact on transfer was also investigated. Two control groups (Indians and Glaswegians) and the experimental group (Glaswasians) were recorded reading English and Hindi sentences containing multiple phones which were examined for multiple phonetic features (/t/-VOT, /l/-F2-F1 difference, /b d g/-Relative Burst Intensity). In both languages, Glaswasian /t/ and /g/ became more Glaswegian-like (assimilation), whereas F2-F1 difference in /l/ became exaggeratedly Indian-like (dissimilation). Higher Indian Contact was associated with more native-like values in /t/ and /l/ in Hindi but had no influence on /g/. Higher Glaswegian Contact was related to increased assimilation of /g/ in English but had no effect on /l/ and /t/.
