This study investigated phonetic backward transfer in the ethnolinguistic minority of first-generation bilingual immigrant Indians in Glasgow ‘Glasgow-Indians’ in relation to Flege’s Speech Learning Model, which predicts ‘assimilation’ and ‘dissimilation’ of sound categories. The study explored whether and how sounds of Glasgow-Indian native language (Hindi) and dialect (Indian English) are influenced by sounds of the dominant host language/dialect (Glaswegian English). The role of their Glaswegian and Indian Identity was also examined. Two control groups (Indians and Glaswegians) and the experimental group (Glasgow-Indians) were recorded reading in English and Hindi words containing two phones (/t/ and /d/− voice onset time (VOT)). In both languages, Glasgow-Indian VOT became more Glaswegian-like (assimilation) and to a greater degree in English than Hindi in /t/. Increasing Glaswegian Identity increased assimilation in /t/ but had no effect on /d/, whereas increasing Indian Identity decreased assimilation in /d/ but had no effect on /t/.
