ItemPreaspiration in Italian voiceless geminate and singleton stops(Guarant, 2023-08-07)This study is the first to explore from a cross-regional perspective acoustic phonetic features of preaspiration in both voiceless geminate and singleton stops in Italian, a language for which preaspiration is most typically associated with voiceless geminate stops. Frequency of preaspiration occurrence and duration are investigated in a controlled production experiment involving twelve speakers from two regional areas with different dialect substrata. Results reveal that preaspiration occurs for both geminates and singletons in both regions, with area-specific differences in frequency possibly linked to regional differences in phonetic voicing patterns of intervocalic singletons. We conclude that preaspiration in Italian stops may be best associated with phonetic voicing status, not phonological length.

ItemSociophonetic Variation in Vowel Categorization of Australian English(SAGE PUBLICATIONS LTD, 2023-10-13)This study involves a perceptual categorization task for Australian English, designed to investigate regional and social variation in category boundaries between close-front vowel contrasts. Data are from four locations in southeast Australia. A total of 81 listeners from two listener groups took part: (a) so-called mainstream Australian English listeners from all four locations, and (b) L1 Aboriginal English listeners from one of the locations. Listeners heard front vowels /ɪ e æ/ arranged in 7-step continua presented at random. Varied phonetic contexts were analyzed, with a focus on coda /l/ because of a well-known prelateral merger of /e æ/ through mid-vowel lowering (e.g., celery-salary) reported to occur in some communities in this part of Australia. The results indicate that regional variation in Australian English is evident in perception. In particular, merging of /el/-/æl/ is shown to occur in the southernmost regions analyzed, but rarely in the northern regions of the geographical area under investigation. Aside from regional variation observed, age was also a factor in how participants responded to the task: older speakers had more merger than younger speakers in many locations, which is a new finding-previously, the merger was thought to be increasing in frequency over time, yet here we see this in only one location. Aboriginal English listeners also responded differently when compared with mainstream Australian English listeners. By analyzing the perception results across a variety of regional locations, with data from two different Australian social groups in the same location, this study adds a new dimension to our understanding of regional and social variations in Australian English.

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.

ItemNafsan(CAMBRIDGE UNIV PRESS, 2023-08)Nafsan (ISO 639-3: erk, Glottocode: sout2856), also known as South Efate, is a Southern Oceanic language of Vanuatu. It is spoken in Erakor, Eratap and Pango, three villages situated along the southern coast of the island of Efate (Figure 1) (Clark 1985, Lynch 2000, Thieberger 2006). Nafsan is also closely related to Eton, Lelepa, Nakanamanga and Namakura, spoken further to the north on Efate and some smaller neighbouring islands.1 Nafsan is often described as the southernmost member of the North-Central Vanuatu group of languages, and the Nafsan and Eton-speaking communities are noted to be at the core of ‘an unmistakable area of innovation’ compared to their northern neighbours (Clark 1985: 25). Though crosslinguistic comparisons suggest a clear boundary between North-Central Vanuatu languages and languages of the Southern Vanuatu group, there is evidence that Nafsan speakers have both linguistic and cultural links to the southern islands, suggestive of complex historical relationships between the populations of the central and southern regions (Lynch 2004; Thieberger 2007, 2015). In terms of the sound system, Nafsan is noted to be of particular interest because it ‘forms a transition between the phonologically more conservative languages to the north and the more “aberrant” languages to the south’ (Lynch 2000: 320), and exhibits phonotactic patterns which are complex and typologically uncommon, particularly among Oceanic languages (Thieberger 2006).

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.
