Articulatory adaptations to the effect of nasality on vowel formants in Xinfeng Tieshikou Hakka
Articulatory compensation for mismatches between expected and perceived formants appears to be a fundamental component of speech production. We pursue the hypothesis that this component of speech production accounts for observed differences in articulation between oral and nasal vowel pairs in natural language production. The empirical focus is Xinfeng Tieshikou Hakka (XTH). We report acoustic analyses of three oral-nasal vowel pairs, [i]-[ĩ], [e…

Nonlinear second-order dynamics describe labial constriction trajectories across languages and contexts
Effects of minimal pair competitors on voice onset time and pitch accent production in South Swedish
Zhongjiang Chinese
Zhongjiang Chinese (中江话) is a variety of Mandarin Chinese, one of the ten language families in China (Mandarin, Cantonese, Xiang, Min, Gan, etc.,). Sometimes the term “Mandarin” is also used to refer to the national lingua franca “Putonghua”. We refer to the national lingua franca as “Standard Mandarin” and reserve the term Mandarin (官话) to refer to the language family, as distinct from other families, e.g., Cantonese, Xiang, Min, Gan, etc. Withi…
Neural inhibition during speech planning contributes to contrastive hyperarticulation
A dynamic neural field model of leaky prosody
Recent work has shown that lexical items come to take on the phonetic characteristics of the prosodic environments in which they are typically produced, a phenomenon referred to as "leaky prosody". Focusing on pitch patterns in Mandarin, we show that leaky prosody can be derived from a flat (i.e., non-transformational, non-optimizing) model of speech production. Formalized using Dynamic Field Theory, in our model, lexical, phonological, and proso…
Variation, gender and perception
The social categories that characterize a speaker frequently correlate with the use of specific linguistic variables. Research suggests that such correlations are sometimes recognized as socially-indexed meanings. This study examines Japanese individuals’ attitudes toward variables that have been shown to correlate with the social category of gender in production. In particular, we contrast patterns of gendered variation that (i) have been prescr…

Micro-prosody
This article introduces micro-prosody as the study of the duration and timing of speech events. We present a descriptive framework, formalising micro-prosody in terms of gestural landmarks and coordination relations between them, and we use the framework to illustrate different patterns of micro-prosody across languages. We show that potential ambiguity between coordination relations can be resolved by considering how they structure natural varia…
Prosody leaks into the memories of words
Articulatory coordination distinguishes complex segments from segment sequences
Phonological patterning motivates a distinction between complex segments and segment sequences, although it has also been suggested that there might be reliable phonetic differences. We develop the hypothesis that, in addition to their distinct phonological patterning, complex segments differ from segment sequences in how constituent articulatory gestures are coordinated in time. Through computational simulation, we illustrate predictions that fo…
The Role of Acoustic Similarity and Non-Native Categorisation in Predicting Non-Native Discrimination
This study tests whether Australian English (AusE) and European Spanish (ES) listeners differ in their categorisation and discrimination of Brazilian Portuguese (BP) vowels. In particular, we investigate two theoretically relevant measures of vowel category overlap (acoustic vs. perceptual categorisation) as predictors of non-native discrimination difficulty. We also investigate whether the individual listener's own native vowel productions predi…
Evidence for active control of tongue lateralization in Australian English /l
Research on the temporal dynamics of /l/ production has focused primarily on mid-sagittal tongue movements. This study reports how known variations in the timing of mid-sagittal gestures are related to para-sagittal dynamics in /l/ formation in Australian English (AusE), using three-dimensional electromagnetic articulography (3D EMA). The articulatory analyses show (1) consistent with past work, the temporal lag between tongue tip and tongue body…
The role of gestural timing in non-coronal fricative mergers in Southwestern Mandarin
Merger between a voiceless labiodental fricative, [f], and a voiceless velar fricative, [x], is common across languages, including many varieties of Chinese, particularly those spoken in Southwestern China. The sound changes that lead to merger in Southwestern Mandarin varieties are bidirectional: in some, [f] becomes [x]; in others [x] becomes [f]. We conducted a study of phonetic variation in one such variety, Zhongjiang (中江) Chinese, which has…
Bilingual phonology in dichotic perception
Listeners often experience cocktail-party situations, encountering multiple ongoing conversations while tracking just one. Capturing the words spoken under such conditions requires selective attention and processing, which involves using phonetic details to discern phonological structure. How do bilinguals accomplish this in L1-L2 competition? We addressed that question using a dichotic listening task with fluent Malayalam-English bilinguals, in …
Phonological contrast and phonetic variation
Phonological contrast and phonetic variation
2020, Linguistic Society of America. All rights reserved. A field-based ultrasound and acoustic study of Iwaidja, an endangered Australian Aboriginal language, investigates the phonetic identity of nonnasal velar consonants in intervocalic position, where past work has proposed a [+continuant] vs. [−continuant] phonemic contrast. We analyze the putative contrast within a continuous phonetic space, defined by both acoustic and articulatory paramet…
Effects of Surprisal and Entropy on Vowel Duration in Japanese
Research on English and other languages has shown that syllables and words that contain more information tend to be produced with longer duration. This research is evolving into a general thesis that speakers articulate linguistic units with more information more robustly. While this hypothesis seems plausible from the perspective of communicative efficiency, previous support for it has come mainly from English and some other Indo-European langua…
Predictability and phonology
Many papers in this special issue grew out of the talks given at the Symposium “The role of predictability in shaping human language sound patterns,” held at Western Sydney University (Dec. 10–11, 2016). Some papers were submitted in response to an open call; others were invited contributions. This introduction aims to contextualize the papers in the special issue within a broader theoretical context, focusing on what it means for phonological th…
Assessing surface phonological specification through simulation and classification of phonetic trajectories
Many previous studies have argued that phonology may leave some phonetic dimensions unspecified in surface representations. We introduce computational tools for assessing this possibility though simulation and classification of phonetic trajectories. The empirical material used to demonstrate the approach comes from electromagnetic articulography recordings of high-vowel devoicing in Japanese. Using Discrete Cosine Transform, tongue-dorsum moveme…
Consequences of High Vowel Deletion for Syllabification in Japanese
High vowels in Japanese devoice between two voiceless consonants; recent work has shown that devoiced /u/ in this environment is also variably deleted. This paper investigates the syllabification of consonant clusters resulting from vowel deletion. We consider two competing hypotheses from the literature: (H1) that consonant clusters are parsed tautosyllabically into a complex syllable onset and (H2) that consonant clusters are parsed heterosylla…

Syllabification in Moroccan Arabic
Competing proposals on the syllabification of initial consonants in Moroccan Arabic are evaluated using a combination of experimental and modelling techniques. The proposed model interprets an input syllable structure as a set of articulatory landmarks coordinated in time. This enables the simulation of temporal patterns associated with the input syllable structure under different noise conditions. Patterns of stability between landmarks simulate…
Dynamic invariance in the phonetic expression of syllable structure
We asked whether invariant phonetic indices for syllable structure can be identified in a language where word-initial consonant clusters, regardless of their sonority profile, are claimed to be parsed heterosyllabically. Four speakers of Moroccan Arabic were recorded, using Electromagnetic Articulography. Pursuing previous work, we employed temporal diagnostics for syllable structure, consisting of static correspondences between any given phonolo…
