New ways of analysing the history of varieties of English - an acoustic analysis of early pop music recordings from Ghana

摘要

I will present first results of an acoustic analysis of Ghanaian “Highlife” songs from the 1950s to 1960s. My results show that vowel subsystems in the 1950s and 1960s show a different kind of variation than in present-day Ghanaian English. Particularly the STRUT lexical set is realized as /a, ɔ/ in the Highlife-corpus. Today, it is realized with three different vowels in Ghanaian English, /a, ε, ɔ/ (Huber 2004: 849). A particular emphasis will also be on the way Praat (Boersma and Weenink 2011) can be used to analyze music recordings.
