The contrast and positional/contextual variation in Serbian laterals
This study uses electropalatography to investigate the production of Serbian laterals /l/ and /ʎ/ focusing on their place of articulation difference and susceptibility to variation as a function of utterance position and vowel context. Data obtained from four speakers producing these sounds utterance-initially, medially intervocalically, and finally and next to /a/, /i/, and /u/. The two consonants were found to be well-differentiated both in ter…
Articulatory Methods for the Study of Second Language Speech
In the introduction to this special issue on articulatory approaches to the study of L2 speech, we first highlight the interest and unique contributions of such methods to the investigation of speech production among second language speakers. This is followed by a brief overview of the four articulatory methods—electropalatography, nasometry, magnetic resonance imaging, and ultrasound—featured in the experimental studies presented in the seven ar…
Linguopalatal contact differences between Japanese geminates and singletons across different places and manners
This study uses electropalatography to examine linguopalatal contact differences between Japanese geminate and singleton consonants of various lingual places and manners of articulation. The analysis of over 8,000 tokens of these consonants produced by five Japanese speakers in three sets of stimuli (varying by the word lexical status, contrastive focus, and position within an utterance) showed significantly stronger constrictions for geminates o…
Articulatory Characteristics of Secondary Palatalization in Romanian Fricatives
The production of fricatives involves the complex interaction of articulatory constraints resulting from the formation of the appropriate oral constriction, the control of airflow through the constriction so as to achieve frication and, in the case of voiced fricatives, the maintenance of glottal oscillation by attending to transglottal pressure. To better understand this mechanism in a relatively understudied language, we explore the articulator…
Stop-Lateral Clusters in French and Spanish
While both French and Spanish have complex onsets, the languages differ in the variety and distribution of clusters allowed as well as in the realization of voiced stops. The present study examines the effects of C1 voicing, place of articulation, and language on the production of word-initial /pl bl kl gl/ using a combination of electropalatographic (C1 and C2 linguopalatal contact and timing) and acoustic measures (duration and relative intensi…
An MRI-based articulatory analysis of the Kannada dental-retroflex contrast
This paper investigates the production of dental and retroflex stops, fricatives, nasals, and laterals in the Dravidian language Kannada. This is done using articulatory contours extracted from an extensive midsagittal MRI corpus of two female Kannada speakers' static vocal tract postures intended to capture key aspects of phonemic articulations. Articulatory modelling was used to determine a set of components responsible for the implementation o…
Articulatory Insights into the L2 Acquisition of English-/l/ Allophony
In many English varieties, /l/ is produced differently in onsets and codas. Compared with “light” syllable-initial realizations, “dark” syllable-final variants involve reduced tongue tip-alveolar ridge contact and a raised/retracted tongue dorsum. We investigate whether native French and Spanish speakers whose L1 lacks such positionally conditioned variation can acquire English-/l/ allophony, testing the hypotheses that (1) the allophonic pattern…
Language and cluster-specific effects in the timing of onset consonant sequences in seven languages
In this paper, we draw on available data from previous experiments to explore cross-linguistic variation in articulatory overlap in CC onset clusters, taking into account the role of cluster composition. Our sample includes articulography recordings of eleven clusters for seven languages. We find that cross-linguistic variability is conditional on cluster composition. Previous suggestions that languages may have individual global articulatory tim…
Variable assimilation of English word-final /n
The phonetic realization of the English word-final alveolar nasal /n/ is known to be highly variable. Previous articulatory work has reported both gradient and categorical nasal place assimilation including considerable between-speaker differences. This work, however, has largely focused on a small subset of place contexts (namely, preceding velar /k, ɡ/) in a limited number of English varieties. The present article uses electropalatography to st…
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…
Kalasha (Bumburet variety)
Kalasha (ISO 639-3: kls), also known as Kalashamon, is a Northwestern Indo-Aryan language spoken in Chitral District of Khyber Pakhtunkwa Province in northern Pakistan, primarily in the valleys of Bumburet, Rumbur, Urtsun, and Birir, as shown in Figure 1. The number of speakers is estimated between 3000 and 5000. The Ethnologue classifies the language status as ‘vigorous’ (Eberhard, Simons & Fennig 2019) but some researchers consider it ‘threaten…

Research methods in articulatory phonetics I
This article is Part I of a general overview of current methods in articulatory phonetics research. This part deals with methods used to investigate oral gestures-speech-related movements of the tongue, the lips, and the jaw (while Part II is concerned with methods studying laryngeal and nasal gestures, and the entire vocal tract). The focus of the article is on electropalatography, ultrasound, and electromagnetic articulography, with some attent…
Gradient assimilation in French cross-word /n/+velar stop sequences
Articulatory studies have revealed cross-linguistic variation in the realization of cross-word nasal+stop sequences. Whereas languages such as Italian and Spanish show largely categorical regressive place assimilation (Kochetov & Colantoni 2011, Celata et al. 2013), English and German alveolar nasals are often characterized by gradient assimilation, modulated by the degree of overlap with the following gesture (Barry 1991, Ellis & Hardcastle 2002…
Ejective harmony in Lezgian
This paper contributes to the typology of laryngeal harmony by analysing an unusual case of long-distance laryngeal co-occurrence restrictions and alternations in Lezgian. This pattern, previously unmentioned in the phonological literature, is the first known case of alternations involving ejective harmony. In Lezgian, local processes mask the interaction of ejectives and plain voiceless stops. This is robustly supported by our dictionary analysi…
Gradient and Categorical Effects in Native and Non-native Nasal-rhotic Coordination
Languages are known to differ in their patterns of consonant-to-consonant coordination. Acquisition of a second language (L2) therefore involves learning these language-specific coordination patterns and the corresponding coarticulation and assimilation processes within and across words. This paper seeks to determine whether L2 learners of English acquire the target pattern of gradient assimilation of the nasal + rhotic sequence in English (e.g. …
Supralaryngeal implementation of length and laryngeal contrasts in Japanese and Korean
This article investigates supralaryngeal characteristics of Japanese and Korean length and laryngeal contrasts in stops and affricates. Electropalatography data collected from five Japanese and five Korean speakers revealed similar differences among the consonants in the degree of linguopalatal contact and duration of the closure. Japanese (voiceless) geminate and Korean fortis obstruents were most constricted and had the longest duration (althou…
Integrating sound symbolism with core grammar
Speech rate effects in Russian onset clusters are modulated by frequency, but not auditory cue robustness
Integrating sound symbolism with core grammar
Fifty cases of sound-symbolic expressive palatalization were collected in a typological survey of babytalk registers, diminutive constructions, and other sound-symbolic systems. Analysis of the typological trends and language-particular examples reveals important differences between expressive palatalization and phonologically motivated palatalization. To account for expressive palatalization, we propose a novel set of EXPRESS(X) constraints in O…
Acoustics of Russian voiceless sibilant fricatives
This study investigated acoustic properties of the four-way contrast in Russian voiceless sibilant fricatives (/ssjʂ ʃj/). Words with these consonants, occurring in a variety of phonetic contexts, were elicited from 10 Russian native speakers. Measurements were made of duration, centre of gravity (COG) and intensity of fricative noise, as well as of formants F1-F3 during the following vowel. The results revealed that the anterior vs. posterior co…
Examination of the grooving patterns of the Czech trill-fricative
Spatial and dynamic aspects of retroflex production
Patterns and scales of expressive palatalization
This article argues for the existence of expressive palatalization (E-Pal) – a phonologically unmotivated process that applies in sound symbolism, diminutive constructions, and babytalk registers. It is proposed that E-Pal is grounded in iconic sound-meaning associations exploiting acoustic properties of palatalized consonants and thus is inherently different from regular phonological palatalization (P-Pal). A cross-linguistic survey of patterns …
Phonology and phonetics of epenthetic vowels in loanwords
Spatial and dynamic aspects of retroflex production
Phonetic variability and grammatical knowledge
The study reported here uses articulatory data to investigate Korean place assimilation of coronal stops followed by labial or velar stops, both within words and across words. The results show that this place-assimilation process is highly variable, both within and across speakers, and is also sensitive to factors such as the place of articulation of the following consonant, the presence of a word boundary and, to some extent, speech rate. Gestur…
Perception of Place and Secondary Articulation Contrasts in Different Syllable Positions
This study investigated the perception of place and secondary articulation contrasts in different syllable positions by Russian and Japanese listeners. The consonants involved in the study were the Russian plain (velarized) and palatalized labial and coronal voiceless stops in syllable-initial and syllable-final positions at word boundaries. The findings revealed substantial asymmetries in the perception of the contrasts by both groups of listene…

The role of social factors in the dynamics of sound change
This article presents results of a sociolinguistic study of a Northern Russian dialect as spoken in a small rural community of Pokcha in the Western Urals, Russia. Because of a number of social influences, the dialect has been undergoing a rapid shift towards Standard Russian. The study examines two sound changes in progress: (1) a merger of unstressed mid back vowels and (2) a split of a post-alveolar fricative into two phonemes. The focus of th…

Coronal place contrasts in Argentine and Cuban Spanish
Theoretical and descriptive work on Spanish phonetics and phonology has been largely based on Peninsular varieties. This study uses electropalatography (EPG) to investigate articulatory characteristics of coronal consonant contrasts in Argentine and Cuban Spanish. Simultaneous EPG and acoustic data were collected from five speakers from Buenos Aires (Argentina) and three speakers from Havana (Cuba) reading sentences with various syllable-initial …
Komi-Permyak coronal obstruents
Komi-Permyak (Finno-Ugric) has a typologically rare contrast between palatal stops and palatal affricates; the latter are also contrastive with postalveolar affricates. In addition, the language has a relatively uncommon three-way place contrast among sibilant fricatives. This paper investigates acoustic properties of the Komi-Permyak voiceless coronal obstruents in different positional contexts. An acoustic analysis of data from six native speak…

Place assimilation and phonetic grounding
This paper investigates predictions made by the ‘phonetic knowledge hypothesis’ (Jun 1995, 2004, Hayes & Steriade 2004) about the relation between perceptibility of stops and common patterns of major place assimilation. In two perceptual experiments, stimuli with Russian released and unreleased voiceless stops in clusters were presented for identification of 56 listeners, native speakers of Russian, Canadian English, Korean and Taiwanese Mandarin…

Japanese mimetic palatalisation revisited
This article re-examines ‘conflicting directionality’ in Japanese mimetic words, a distributional pattern in which palatalisation is preferentially realised on the rightmost of two coronal consonants, but on the leftmost consonant in a word without coronals. Analysis of the original dictionary evidence given in support of this generalisation and an exhaustive search of the Japanese mimetic stratum reveal both several counterexamples to conflictin…
