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.

ItemAcoustic analysis of the effects of 24 hours of sustained wakefulness(Australasian Speech Science and Technology Association, 2010)The effect of 24 hours of sustained wakefulness on the speech of healthy adults is poorly documented. Therefore, speech samples were systematically acquired (e.g., every four hours) from 18 healthy adults over 24 hours. Stimuli included automated and extemporaneous tasks, sustained vowel and a read passage. Measures of timing and frequency were derived acoustically using Praat and significant changes were observed on all tasks. The effect of fatigue on speech was found to be strongest just before dawn (after 22 hours). Key features of timing (e.g., mean pause length), frequency (e.g., F4 variation) and power (alpha ratio) changed as a function of increasing levels of fatigue. Index Terms: fatigue, voice, tiredness, clinical marker

ItemPhonetic cues to accentual prominence in Bengali English(City University of Hong Kong, 2011)This paper examines the acoustic correlates of accentual prominence in English spoken by L1 Bengali speakers. The acoustic phonetic correlates of stressed unaccented vowels, and stressed vowels produced in positions of narrow focus were compared. As observed for many varieties of English, the main correlates of accentual prominence in narrow focused contexts were presence of/and extent of f0 movement throughout the stressed vowel, followed by a concomitant increase in RMS-db. Vowels were also longer compared to stressed unaccented vowels although the differences were relatively small and highly variable.

ItemTonal alignment of focal accents in two varieties of Indian English(University of Canterbury, 2014)This study examines the tonal alignment of focal rising pitch movements in two varieties of Indian English: Bengali and Kannada English. The results revealed that all speakers use a bitonal rising pitch accent to realise focal prominence. An examination of the alignment patterns of Low and High tone targets shows that a late rising L*+H accent on focally prominent words is characteristic of Bengali English speakers whereas Kannada English speakers use an L+H* accent. Consistent with the literature, the phonetic location of the tone targets is also strongly correlated with accented syllable duration and a range of other phonetic factors.

ItemProsodic effects on vowel spectra in three Australian languages(International Speech Communications Association, 2014)In this paper, the spectral properties of vowels in three Australian languages are examined with the aim of determining whether prosodic prominence and domain-edge effects on formant frequencies, formant variability and vowel space dispersion can be identified. It is shown that these vowel systems are sufficiently dispersed, with an anchoring of the system by the open central vowel. It is also shown that for Burarra but not for Gupapuyngu or Warlpiri there is some evidence of prosodically-driven hyper-articulation. Finally, the data indicate pre-boundary lengthening in all three languages, which in some cases appears to be associated with changes in vowel quality.
