Production III: Consonants Across Languages
ASPIRATION AND VOICING OF CHINESE AND ENGLISH PLOSIVES
DAVID DETERDING, Nanyang Technological University
FRANCIS NOLAN, University of Cambridge
|The six plosives of Standard Chinese are compared with those of RP British English, to see if there is a difference in their aspiration and/or voicing. Recordings of 7 speakers from China reading words beginning with each of the 6 plosives are compared to similar recordings of 7 speakers of RP British English, and it is found that there is little difference in the aspiration of the plosives in the two languages, though there is a difference in the voicing during the closure when the plosive occurs between two vowels.|
Flapping in unconstrained alveolars
Daniel Recasens, Universitat Autònoma de Barcelona and Institut d'Estudis Catalans
|Electropalatographic data for the alveolar nasal, the alveolar tap and clear /l/ in two Catalan dialects reveal that all three consonants undergo continuous closure fronting after low and back rounded vowels in VCV sequences, next to these same vowels in postpausal and prepausal position, and next to labial and velar consonants in consonant clusters. It is argued that this flapping mechanism is associated with the low degree of tongue constraint involved in the production of the three alveolars.|
Understanding flapping in Xiangxiang Chinese: acoustic and aerodynamic evidence
TING ZENG, Department of Chinese, Translation and Linguistics, City University of Hong Kong, Hong Kong
|This paper investigates the phonetic nature of flapping for /d/ and /th/ in intervocalic pre-unstressed and pre-stressed positions at a normal speech rate in Xiangxiang Chinese. The resulting data were approached in two perspectives: acoustic and aerodynamic. It was found that the acoustic and aerodynamic patterns were significantly correlated with each other, and both show that /d/ and /th/ exhibit considerable intra-speaker variation which constitutes a continuum from typical [d]s and [th]s to typical flaps in intervocalic position, indicating an articulatory continuum from long and complete oral closure for typical [d]s and [th]s to short and incomplete oral closure for typical flaps. This mirrors a gradient process which springs from a single mechanism common to each speaker. A model of consonant-vowel co-articulation is proposed and other related problems raised by these results are also discussed.|
EMA study of the coronal emphatic and non-emphatic plosive consonants of Moroccan Arabic

|Abstract Our EMA data show that the longer VOT duration of the coronal non-emphatic /t/ compared to its emphatic cognate /T/ is due to: (i) the laminal articulatory contact during /t/ vs., contact apical during /T/, (ii) the jaw position which reaches its target at the release of /t/, and before it during /T/. We propose that this apical contact during the emphatics, and their unexpectedly high jaw position, are bound to the biomechanics constrains of emphasis (pharyngealization).|
Articulatory Characteristics of Anterior Click Closures in Nǀuu
Bonny Sands, Northern Arizona University
Johanna Brugman, Cornell University
Mats Exter, University of Cologne
Levi Namaseb, University of Namibia
Amanda Miller, Cornell University
|We document the anterior places of articulation in the Nǀuu click types [ǀ, ǃ, ǁ, ǂ] using palatography and linguography. We discuss the variability seen across speakers and compare these articulations with the cross-linguistic variation reported for comparable clicks. We show that inter-speaker variability found for anterior click place of articulation is comparable to that found for coronal pulmonic consonants.|
