Acoustic properties of the monophthongs of Assamese Indian English speakers

Abstract This study investigates acoustic properties of the monophthongal vowels of English as spoken by 20 Assamese speakers in North East India, based on their medium of education being English or Assamese. Research suggests that English in India may be converging to a more homogenous standard, at least among educated speakers, despite common first language (L1) differences (Maxwell & Fletcher, 2009; Sirsa & Redford, 2013; Wiltshire, 2020). Assamese, a member of the Indo‐Aryan language family, shares phonological characteristics with surrounding languages from the Tibeto‐Burman family. We find that the vowels of Assamese Indian English speakers maintain characteristics reflecting their L1, especially those similar to local Englishes spoken by L1 Tibeto‐Burman speakers. However, English‐medium educated speakers do more closely approximate the norms of the central Indian standard, suggesting that although North East Indian English norms diverge from those of central India, there is some convergence across India among English‐medium educated speakers, regardless of L1s.
