“…Our literature review (see description below) showed that around 75% of studies published in journals included ten participants or fewer; around 46% included five participants or fewer. This is also in line with Kochetov (2020), who reported the median number of participants in an EMA study to be five. Early studies (e.g., earlier than 2003) have often only included one or two participants, and it was not uncommon for one of the authors to be a participant.…”

This paper reviews data collection practices in electromagnetic articulography (EMA) studies, with a focus on sensor placement. We first introduce electromagnetic articulography as a method. We then focus on existing data collection practices. Our overview is based on a literature review of 905 publications from a large variety of journals and conferences, identified through a systematic keyword search in Google Scholar. The review shows that experimental designs vary greatly, which in turn may limit researchers' ability to compare results across studies. Finally, we describe an EMA data collection procedure that includes an articulatory-driven strategy for determining where to position sensors on the tongue without causing discomfort to the participant. We also evaluate three approaches for preparing (NDI Wave) EMA sensors reported in the literature with respect to the duration the sensors remain attached to the tongue: 1) attaching out-of-thebox sensors, 2) attaching sensors coated in latex, and 3) attaching sensors coated in latex with an additional latex flap. Results indicate no clear general effect of sensor preparation type on adhesion duration. A subsequent exploratory analysis reveals that sensors with the additional flap tend to adhere for shorter times than the other two types, but that this pattern is inverted for the most posterior tongue sensor.

“…We recorded 11 participants (9 female and 2 male). (Note: Because articulometry experiments are long and demanding, worldwide median participant counts are small (5 as of 2020 44 ). All but one of the participants were native monolingual North American English (NAE) speakers, and the other was a native bilingual NAE and French speaker.…”

Gait change in tongue movement

During locomotion, humans switch gaits from walking to running, and horses from walking to trotting to cantering to galloping, as they increase their movement rate. It is unknown whether gait change leading to a wider movement rate range is limited to locomotive-type behaviours, or instead is a general property of any rate-varying motor system. The tongue during speech provides a motor system that can address this gap. In controlled speech experiments, using phrases containing complex tongue-movement sequences, we demonstrate distinct gaits in tongue movement at different speech rates. As speakers widen their tongue-front displacement range, they gain access to wider speech-rate ranges. At the widest displacement ranges, speakers also produce categorically different patterns for their slowest and fastest speech. Speakers with the narrowest tongue-front displacement ranges show one stable speech-gait pattern, and speakers with widest ranges show two. Critical fluctuation analysis of tongue motion over the time-course of speech revealed these speakers used greater effort at the beginning of phrases—such end-state-comfort effects indicate speech planning. Based on these findings, we expect that categorical motion solutions may emerge in any motor system, providing that system with access to wider movement-rate ranges.

“…Our data come from four female speakers, two from France (FE1: Clermont-Ferrand, FE2: Cherbourg) and two from Quebec, Canada (FQ1: Chicoutimi, FQ2: St-Jean-sur-Richelieu). While small, the number of speakers involved in this study is in keeping with previous EPG research, for which the median sample size is four participants per study (Kochetov, 2020, based on a review of 54 EPG studies published between 2000and 2019.…”

The palatal nasal is one of French’s most variable consonants with attested variants including [ɲ] alongside [nj] and, less frequently, [n] and [ŋ]. Variation is conditioned by both linguistic (position in the word, lexical item, flanking vowels) and speaker variables (in particular, variety). Except for insights provided by the studies reviewed in Recasens (2013), little is known of the articulatory properties of French /ɲ/ including the degree of inter-varietal and -speaker variation or the proportion of coronal and velar depalatalized realizations. We present here an electropalatographic (EPG) study of two European (EF) and two Quebec French (QF) speakers’ /ɲ/ production in both word-medial and -final positions in isolated and contextualized words. Quantitative indices and qualitative investigation of the linguopalatal contact profiles reveal that the EF speakers produced a relatively anterior /ɲ/, differing minimally from /n/ followed by /j/. Whereas one of their QF peers produced uniquely backed velar realizations of /ɲ/, the other speaker had fronted alveolopalatal variants word-medially versus backed velar realizations word-finally, with the latter differing minimally from the /ŋ/ of jogging. These findings are consistent with pathways to depalatalization observed in other Romance varieties and call into question the phonemic status of the palatal nasal in French.
