New insights into /el/-/æl/ merging in Australian English

Abstract

ABSTRACT A merger exists in Australian English in which /el/ is realized as [æl] for a number of speakers, particularly in Victoria. There have also been some observations of /æl/ raising to [el], termed “transposition”. Although thought to be characteristic of older speakers, empirical evidence for transposition is scant. Here we report the discovery of substantive degrees of merging in thirteen older speakers, aged between 51 and 80, from Ocean Grove, Victoria. Auditory and acoustic methods showed bidirectional vowel movement, with speakers converging on both the /æ/ and /e/ phonemes. Increasing velarization of the lateral has been posited as a factor in the development of the merger in Victoria, and thus /l/ quality was also investigated, with null results in terms of direct factors. The lateral, however, was shown to be dark in both syllable onset and coda positions, with evidence for /l/ being clearer in this age group when compared with younger speakers. Lexical frequency and orthography were also investigated as factors, the latter showing a significant effect and suggesting a role for velarization as a contrast maintenance strategy.
