An ultrasound study of Connemara Irish palatalization and velarization
We present the first ultrasound analysis of the secondary palatalization contrast in Irish, analyzing data from five speakers from the Connemara dialect group. Word-initial /pʲ(bʲ) pˠ(bˠ) tʲ tˠ kʲ kˠ fʲ fˠ sʲ sˠ xʲ xˠ/ are analyzed in the context of /iː uː/. We find, first, that tongue body position robustly distinguishes palatalized from velarized consonants, across place of articulation, manner, and vowel place contexts, with palatalized consonants having fronter and/or higher tongue body realizations than their velarized counterparts. This conclusion holds equally for labial consonants, contrary to some previous descriptive claims. Second, the nature and degree of palatalization and velarization depend in systematic ways on consonant place and manner. In coronal consonants, for example, velarization is weaker or absent. Third, the Irish consonants examined resist coarticulation in backness with a following vowel. In all of these respects Irish palatalization is remarkably similar to that of Russian. Our results also support an independent role for pharyngeal cavity expansion/retraction in the production of the palatalization contrast. Finally, we discuss preliminary findings on the dynamics of the secondary articulation gestures. Our use of principal component analysis (PCA) in reaching these findings is also of interest, since PCA has not been employed a great deal in analyses of tongue body movement.
Articulation and neutralization: a preliminary study of lenition in scottish gaelic
Interspeech 2014, 2014
Initial Consonant Mutation in Scottish Gaelic is considered to be morphological, somewhat idiosyncratic, and neutralizing, that is merging either the mutated sound and some underlying sound or merging two mutated sounds. This study explores articulation in one class of mutation, called Lenition (also Aspiration), asking the question of whether these sounds are articulated in the same fashion or not. Comparison of relevant ultrasound images collected from 3 native speakers of Scottish Gaelic shows that speakers maintain distinctions between True Lenition and False Lenition, suggesting that there is incomplete neutralization. Furthermore, when Lenition of two distinct sounds converge on the same target, subjects again keep the two articulations distinct. These results are consistent with a phonological model which distinguishes between surface forms corresponding to different sources, showing very little complete articulatory neutralisation.

Much progress has been made in the last 200 years with regard to understanding the origins and mechanisms of sound change. It is hypothesized that many sound changes originate in biomechanical constraints on speech production or in the misperception of sounds. These production and perception pressures explain a wide range of sound changes across the world's languages, yet we also know that sound change is not inevitable. For example, similar phonological structures have undergone change in many languages yet remained stable in others. In this study, we examine how typologically unusual contrasts are maintained in the face of intense pressures, in order to uncover the potential biomechanical, perceptual, and sociolinguistic factors that facilitate the maintenance of typologically unusual contrasts. We focus on secondary articulation contrasts in Scottish Gaelic rhotics, triangulating auditory, acoustic, and articulatory data in order to better understand the maintenance of contrast in the face of multidimensional typological challenges. Here, individuallevel articulatory strategies are combined with contextual prosodic information in order to maintain acoustic and auditory distinctiveness across three rhotic phonemes. We highlight the need to more comprehensively consider typologically unusual and minority languages in order to test the limits of generalizations about crosslinguistic phonetic typology.

The present ultrasound study investigates lingual coarticulatory resistance and differences in tongue configuration and contextual variability for consonants in syllable onset vs coda position in Catalan /iC#Ci/ sequences. In agreement with comparable ultrasound data for /aC#Ca/ sequences reported in an earlier study, coarticulatory resistance turned out to be less for /r/ (which is realized as a trill in onset position and exhibits a more tap-like realization in coda position), /l/ (which is not strongly dark), /s/ and the alveolopalatal / ɲ / than for /p, t, n, k/. As expected, contextual variability was less for /iC#Ci/ than for /aC#Ca/ sequences due to the highly demanding requirements put on the tongue body by the high front vowel. Regarding the syllable-position-dependent differences, consonants were often longer but not less variable articulatorily in syllable initial than syllable final position. Syllable-position differences in lingual configuration could be ascribed to either a trend for consonants to be more prominent in onset vs coda position or to prominent coarticulatory effects from flanking /i/ rather than from the contextual consonant in the cluster. The conclusion is drawn that the reason why consonants may sound more reduced in coda vs onset position in heterosyllabic clusters is due less to their actual lingual configuration than to their being manifestly shorter and to specific production characteristics which depend not only on the upper articulators but on the jaw cycle as well.
Scottish English is often cited as a rhotic dialect of English. However, in the 70s and 80s, researchers noticed that postvocalic /r/ was in attrition in Glasgow (Macafee, 1983) and Edinburgh (Romaine, 1978;. Recent research confirms that postvocalic /r/ as a canonical phonetically rhotic consonant is being lost in working-class Glaswegian speech. However, auditory and acoustic analysis revealed that the situation was more complicated than simple /r/ vs. zero variation. The derhoticized quality of /r/ seemed to vary socially; in particular male working class speakers often produced intermediate sounds that were difficult to identify. It is clear that although auditory and acoustic analysis are useful, they can only hint at what is going on in the vocal tract. A direct articulatory study is thus motivated.

Phonetic variation in Scottish Gaelic laterals
Journal of Phonetics 47: 1-17, 2014
This paper is an acoustic investigation of laterals in contemporary Scottish Gaelic. Scottish Gaelic is described as having three phonemic laterals /l̪ˠ l̪ʲ l/, which have previously been the subject of small-scale acoustic and static palatographic work. I expand on previous acoustic studies, including static and dynamic formant measures, and consider data from the diverse contemporary Gaelic-speaking population including [1] older speakers in a Gaelic-heartland area, [2] middle-aged speakers living in Glasgow, [3] adolescent speakers in immersion education in a heartland area, [4] adolescents in immersion education in Glasgow. Results suggest overall maintenance of the triple lateral system, but with substantial variation in the production of (phonemically) palatalised laterals in particular, which some young Glaswegians do not produce. These results are discussed with reference to language change in language revitalisation contexts, language contact, and modes of acquisition in revitalisation contexts.
The articulatory dynamics of pre-velar and pre-nasal /æ/-raising in English: An ultrasound study
The Journal of the Acoustical Society of America
Most dialects of North American English exhibit /ae/-raising in some phonological contexts. Both the conditioning environments and the temporal dynamics of the raising vary from region to region. To explore the articulatory basis of /ae/-raising across North American English dialects, acoustic and articulatory data were collected from a regionally diverse group of 24 English speakers from the United States, Canada, and the United Kingdom. A method for examining the temporal dynamics of speech directly from ultrasound video using EigenTongues decomposition [Hueber, Aversano, Chollet, Denby, Dreyfus, Oussar, Roussel, and Stone (2007). in IEEE International Conference on Acoustics, Speech and Signal Processing (Cascadilla, Honolulu, HI)] was applied to extract principal components of filtered images and linear regression to relate articulatory variation to its acoustic consequences. This technique was used to investigate the tongue movements involved in /ae/ production, in order to compare the tongue gestures involved in the various /ae/-raising patterns, and to relate them to their apparent phonetic motivations (nasalization, voicing, and tongue position).

Palatalization in Dublin Irish: the extent of phonetic interference
In: Procedia - social and behavioral sciences 236 (2016), p. 213-218. This paper focuses on palatalization in Irish spoken by Dublin-based bilinguals with English as their first language. It has already been pointed out that English phonetics affects Irish speakers even when Irish is their first language, especially in case of palatalization. The extent of English influence on palatalization in Dublin Irish and the possible reasons behind its inconsistent use acquire special prominence not only in terms of phonetics, but also because in Irish palatalization performs phonological functions.
