ItemNo Preview AvailableProsodic phrasing, pitch range and word order variation in Murrinhpatha(ASSTA, 2022)Like many Indigenous Australian languages, Murrinhpatha has flexible word order with no apparent configurational syntax. We analyzed an experimental corpus of Murrinhpatha utterances for associations between different thematic role orders, intonational phrasing patterns and pitch downtrends. We found that initial constituents (Agents or Patients) tend to carry the highest pitch targets (HiF0), followed by patterns of downstep and declination. Sentence-final verbs always have lower Hif0 values than either initial or medial Agents or Patients. Thematic role order does not influence intonational patterns, with the results suggesting that Murrinhpatha has positional prosody, although final nominals can disrupt global pitch downtrends regardless of thematic role.

ItemPhrase-level and edge marking in Drehu(OPEN LIBRARY OF HUMANITIES, 2022-06-07)This study investigates prosodic correlates of phrasing in Drehu, an Oceanic language from New Caledonia. The analysis is concerned with the demarcation of prosodic levels in the language, namely the Accentual Phrase and the Intonation Phrase. First impressionistic descriptions of Drehu state there is fixed word initial stress, however recent experimental evidence does not support this claim. Instead, it has been suggested that Drehu could be an edge-marking language which relies on right boundary marking. To determine whether the patterns recorded in the literature are borne out, the phonological and phonetic realisation of post-lexical word level prosody is investigated. An experiment was conducted to examine the extent to which fundamental frequency (F0) and duration contribute to boundary marking in Drehu. The results show that F0 cues mark the right boundary of two prosodic levels, the AP and IP, and that the strength of the boundary is related to its level in the prosodic hierarchy. Preboundary lengthening also cues IP boundaries but not AP boundaries.

ItemNasal aerodynamics and coarticulation in Bininj Kunwok: Smoothing Spline Analysis of Variance(ASSTA, 2016-12-06)Nasal phonemes are well represented within the lexicon of BininjKunwok.1 Thisstudyexaminesintervocalic,wordmedial nasals and reports patterns of coarticulation using a Smooth- ing Spline Analysis of Variance (SSANOVA). This allows for detailed comparisons of peak nasal airflow across six female speakers of the language. Results show that in a VNV sequence there is very little anticipatory vowel nasalisation and greater carryover into a following vowel. The maximum peak nasal flow is delayed for coronals when compared to the onset of oral closure in the nasal, indicating a delayed velum opening gesture. The velar place of articulation is the exception to this pattern with some limited anticipatory nasalisation. The SSANOVA has shown to be an appropriate technique for quantifying these patterns and dynamic speech data in general.

ItemProsodically Conditioned Consonant Duration in Djambarrpuyŋu.(SAGE Publications, 2019-03-01)Cross-linguistically, segments typically lengthen because of proximity to prosodic events such as intonational phrase or phonological phrase boundaries, a phrasal accent, or due to lexical stress. Australian Indigenous languages have been claimed to operate somewhat differently in terms of prosodically conditioned consonant lengthening and strengthening. Consonants have been found to lengthen after a vowel bearing a phrasal pitch accent. It is further claimed that this post-tonic position is a position of prosodic strength in Australian languages. In this study, we investigate the effects of proximity to a phrasal pitch accent and prosodic constituent boundaries on the duration of stop and nasal consonants in words of varying lengths in Djambarrpuyŋu, an Australian Indigenous language spoken in northeast Arnhem Land, Northern Territory, Australia. Our results suggest that the post-tonic consonant position does not condition longer consonant duration compared with other word-medial consonants, with one exception: Intervocalic post-tonic consonants in disyllabic words are significantly longer than word-medial consonants elsewhere. Therefore, it appears that polysyllabic shortening has a strong effect on segment duration in these data. Word-initial position did not condition longer consonant duration than word-medial position. Further, initial consonants in higher-level prosodic domains had shorter consonant duration compared with domain-medial word-initial consonants. By contrast, domain-final lengthening was observed in our data, with word-final nasals preceding a pause found to be significantly longer than all other consonants. Taken together, these findings for Djambarrpuyŋu suggest that, unlike other Australian languages, post-tonic lengthening is not a cue to prosodic prominence, whereas prosodic domain-initial and -final duration patterns of consonants are like those that have been observed in other languages of the world.

ItemAustralia and New Guinea(Oxford University Press, 2021)
This handbook presents detailed accounts of current research in all aspects of language prosody, with chapters written by leading experts from various disciplines. The last four decades have seen major theoretical and empirical breakthroughs in the field, many of them informed by interdisciplinary approaches, as reflected in this volume. Following an introductory chapter covering the fundamentals of language prosody research, Parts II and III explore prosody in speech production and in relation to linguistic structure. Part IV provides overviews of prosodic systems across the world, with case studies from Africa, Asia, Europe, Australia and the Pacific, and the Americas. The chapters in Parts V, VI, and VII investigate prosody in communication, in language processing, and in language acquisition (respectively), while Part VIII examines prosody in technology and the arts.

ItemNasal coarticulation in Bininj Kunwok: An aerodynamic analysis(Cambridge University Press (CUP), 2020-12-01)Bininj Kunwok (BKw), a language spoken in Northern Australia, restricts the degree of anticipatory nasalization, as suggested by previous aerodynamic and acoustic analyses (Butcher 1999). The current study uses aerodynamic measurements of speech to investigate patterns of nasalization and nasal articulation in Bininj Kunwok to compare with Australian languages more generally. The role of nasal coarticulation in ensuring language compre-hensibility a key question in phonetics research today is explored. Nasal aerodynamics is measured in intervocalic, word-medial nasals in the speech of five female speakers of BKw and data are analyzed using Smoothing Spline Analysis of Variance (SSANOVA) and Functional Data Analysis averaging techniques. Results show that in a VNV sequence there is very little anticipatory vowel nasalization with no restriction on carryover nasalization for a following vowel. The maximum peak nasal flow is delayed until the oral release of a nasal for coronal articulations, indicating a delayed velum opening gesture. Patterns of anticipatory nasalization appears similar to nasal airflow in French non-nasalized vowels in oral vowel plus nasal environments (Delvaux et al. 2008). Findings show that Bininj Kunwok speakers use language specific strategies in order to limit anticipatory nasalization, enhancing place of articulation cues at a site of intonational prominence which also is also the location of the majority of place of articulation contrasts within the language. Patterns of airflow suggest enhancement and coarticulatory resistance in prosodically prominent VN and VNC sequences which we interpret as evidence of speakers maintaining a phonological contrast to enhance place of articulation cues.

ItemThe alignment of F0 tonal targets under changes in speech rate in Drehu(Nature Research, 2020-04-01)This study investigates fundamental frequency alignment to segmental landmarks in Drehu, an Oceanic language. The authors present a production experiment that aimed to evaluate the marking of prosodic prominence, and in particular, the tonal marking of prominence, within the autosegmental-metrical phonology, since stress and prominence system of the language has not been phonetically investigated. A rate manipulation paradigm was chosen to test the segmental anchoring hypothesis, namely, to see whether prominence lending tonal movements exhibit a constant slope due to rate manipulation and whether tonal targets can be associated to segmental anchoring points in the speech stream. The authors find that a rising tonal movement, between a word initial low (L), and a word final high (H) tone, is the most frequent tonal pattern. The word initial L tone seeks to align with the left edge whereas the H tone, at the right edge, seeks to anchor to the last full syllable. In fast speech, tonal targets are produced closer together but the slope remains constant in both speech rates. High tones seek to anchor to the word-final syllable, yet not to any specific segment which suggests a weak version of the segmental anchoring hypothesis applies.

ItemFundamental Frequency and Regional Variation in Lifou French(SAGE PUBLICATIONS LTD, 2022-12)This study presents two experiments aimed at investigating tune-to-text alignment and pitch scaling in Lifou French, a variety spoken by bilingual speakers of French and Drehu. Descriptions of New Caledonian French have focussed on language use of European descendants or the variety spoken in the urban region, neglecting emergent varieties spoken by the indigenous population in rural areas, like the island Lifou. Due to the reduced inventory of pitch accents, dialectal variation in French intonation has proved to be difficult to detect, which has led to the assumption that French has a relatively homogeneous intonation system across its varieties. This study shows that fine-grained phonetic differences in speaking tempo and at the level of tonal alignment as well as in the scaling of AP-final peaks can be attributed to dialectal variation.

ItemPhonetic evidence for phonotactic change in Nafsan (South Efate)(Pacini Editore SpA, 2020)Nafsan, an Oceanic language of central Vanuatu, is notable for the complex phonotactic structures it exhibits compared to languages spoken further to the north, and compared to the general preference for CV syllables among Oceanic languages. Various types of heterorganic consonant clusters are found in syllable onsets, and are thought to have arisen from the loss of selected medial vowels. Medial vowel deletion is suggested to be a process of change which has been underway for some time in the language, but the details of how this process operates have not been fully clear. Unresolved questions relating to the status of length in the vowel system and the location of lexical prominence have posed a challenge to arriving at a detailed description of vowel deletion and its consequences. Drawing together recent phonetic analyses and previous work, this paper provides an overview of phonotactic structures in contemporary Nafsan and outlines the main factors which lead to the deletion of medial vowels and result in the complex syllable onsets observed today.
