The following study explores the extent to which American English has influenced the phonology of Singapore English, with a specific look at the TRAP-BATH [æ]/[ɑː] vowels. While Singapore has traditionally regarded British English as the norm due to past historical colonial ties, increasing American media exposure raises the possibility of emerging and new phonological change. This study explores this possibility in Singaporean university students, examining their vowel productions with lexical items from the BATH lexical set. The author also hypothesises that American media influence would in fact cause the adoption of the [æ] vowel for lexical items in the BATH set. Six Singaporean university students participated in a reading task and elicitation task to capture their pronunciation of certain BATH lexical items. Results show an overwhelming preference for the British /ɑ/ vowel, with limited productions of the American /æ/ vowel. Productions of the /æ/ vowel appear to be word specific and did not reflect a larger systemic shift of Singapore English adopting American English features consistently. No significant differences were observed across gender and ethnic groups. Overall, this paper finds that American English influence may be present, but remains limited and is not reflective of a broader change in the vowel production of Singapore English. This study contributes to ongoing discussions on Singapore English and how it continues to navigate between established linguistic norms.
