Vowel systems in Australian English are changing dynamically. Acoustic analysis reveals systemic shifts and parallel movements between monophthongs and diphthongs over 25 years.

Area of Science:

  • Phonetics and phonology
  • Sociolinguistics
  • Acoustic analysis of speech

Background:

  • Vowel systems exhibit dynamic changes, with phonetic disruptions having systemic consequences.
  • Previous research confirms predictable patterns of sound change in English dialects.
  • Australian English provides a unique case study for examining vowel system evolution.

Purpose of the Study:

  • To investigate the nature and patterns of vowel change in Australian English.
  • To compare acoustic data from two distinct time points separated by 25 years.
  • To identify systemic effects and movement patterns within the vowel system.

Main Methods:

  • Collection and acoustic analysis of vowel data from two subject groups.
  • Multivariate analyses of variance (MANOVA) to detect significant acoustic differences.

Related Experiment Videos

  • Examination of phonetic space to map monophthong and diphthong movements.

    • Main Results:

    • Significant acoustic differences were found between the two data sets, confirming systemic effects.
    • Evidence of chain and parallel shifts within vowel classes was observed.
    • A close correspondence between monophthong and diphthong movement in phonetic space was identified.

    Conclusions:

    • Vowel change in Australian English is systemic and follows predictable patterns.
    • Monophthong and diphthong changes are interconnected, influencing each other in parallel.
    • The study provides strong evidence for ongoing, dynamic evolution within the Australian English vowel system.
