    They Talk Muṯumuṯu: Variable Elision of Tense Suffixes in Contemporary Pitjantjatjara
    Wilmoth, S ; Defina, R ; Loakes, D (MDPI AG, 2021)
    Vowel elision is common in Pitjantjatjara and Yankunytjatjara connected speech. It also appears to be a locus of language change, with young people extending elision to new contexts; resulting in a distinctive style of speech which speakers refer to as muṯumuṯu (‘short’ speech). This study examines the productions of utterance-final past tense suffixes /-nu, -ɳu, -ŋu/ by four older and four younger Pitjantjatjara speakers in spontaneous speech. This is a context where elision tends not to be sociolinguistically or perceptually salient. We find extensive variance within and between speakers in the realization of both the vowel and nasal segments. We also find evidence of a change in progress, with a mixed effects model showing that among the older speakers, elision is associated with both the place of articulation of the nasal segment and the metrical structure of the verbal stem, while among the younger speakers, elision is associated with place of articulation but metrical structure plays little role. This is in line with a reanalysis of the conditions for elision by younger speakers based on the variability present in the speech of older people. Such a reanalysis would also account for many of the sociolinguistically marked extended contexts of elision.

    Scaling processes of clause chains in Pitjantjatjara
    Defina, R ; Torres, C ; Stoakes, H (Interspeech, 2020)
    Clause chains are a syntactic strategy for combining multiple clauses into a single unit. They are reported in many languages, including Korean and Turkish. However, they have seen relatively little focused research. In particular, prosodic features are often mentioned in descriptions of clause chaining, however there have been vanishingly few investigations. Corpus-based studies of the prosody of clause chains in two unrelated languages of Papua New Guinea report that they are typically produced as a sequence of Intonation phrases united by pitch-scaling of the L% boundary tones in each clause with only the final, finite, clause descending to a full L%. The present study is the first experimental investigation of the prosody of clause chains in Pitjantjatjara. This paper focuses on one type of clause chain found in the Australian Indigenous language Pitjantjatjara. We examine a set of 120 clause chains read out by three native Pitjantjatjara speakers. Prosodic analysis reveals that these Pitjantjatjara clause chains are produced within a single Intonational Phrase. Speakers do not pause between the clauses in the chain, there is consistent linear downstep throughout the phrase and additionally phrase final lowering occurs at the end of the utterance. This differs from previous impressionistic studies of the prosody of clause chains.
