Abstract

Northern Minnesota English is a dialect that is suspected to be perceptually different from other Minnesota dialects (Bartholdi 2015). The current study seeks to investigate whether there is any acoustic phonetic evidence to prove and/or disprove these impressionistic claims. To do this, acoustic data was collected from twenty participants from Northern Minnesota who uttered 11 different English vowels ([i, ɪ, e, ɛ, æ, ɑ, ɔ, o, ʊ, u, ʌ]). Those utterances were then compared and contrasted with vowel sounds uttered by 32 Central Minnesota English speakers, which were originally collected by Koffi (2013). The findings from this study confirm the impressionistic claims which state that Northern Minnesota English speakers sound slightly different from other Minnesotans, specifically Central Minnesota English speakers. However, these two dialects are not completely different. Despite some perceptible distinctions, both dialects still manifest the same phonological patterns: merged [ɑ] and [ɔ] vowels, raising [ɪ] above [e], and fronting and lowering [ʊ].

Author Bio

Ettien Koffi, Ph.D. linguistics, teaches at Saint Cloud State University, MN. He is the author of five books and author/co-author of several dozen articles on acoustic phonetics, phonology, language planning and policy, emergent orthographies, syntax, and translation. His acoustic phonetic research is synergetic, encompassing L2 acoustic phonetics of English (Speech Intelligibility from the perspectives of the Critical Band Theory), sociophonetics of Central Minnesota English, general acoustic phonetics of Anyi (a West African language), acoustic phonetic feature extraction for application in Automatic Speech Recognition (ASR), Text-to-Speech (TTS), Speech-to-Text (STT), Intelligent Systems, and voice biometrics for speaker verification.
