Abstract Loops are well known as the elliptical tongue fleshpoint paths in vowel-consonant-vowel (VCV) sequences with a velar consonant. However, the discussion about the relative influences of aerodynamics, active motor control and biomechanics on loops is controversial. In order to characterize the biomechanical influence, the design of the current study was specifically based on V1-V2-V1 sequences with no consonants involved, recorded by means of electromagnetic articulography (EMA). In this context, we found evidence that the loop shape varies systematically with the angle of the main movement line between the vowels V1 and V2. Moreover, the regular angle-dependence of the loop shape is examined for eleven male and seven female German adults under different conditions for speaking rate (normal and slow) and for jaw mobility (large, small and no bite block). Model simulations suggest that both the loops and the angle-dependence of their shape can be attributed to biomechanical properties of the extrinsic tongue muscles.

One of the frequent questions by users of the mixed model function lmer of the lme4 package has been: How can I get p values for the F and t tests for objects returned by lmer? The lmerTest package extends the 'lmerMod' class of the lme4 package, by overloading the anova and summary functions by providing p values for tests for fixed effects. We have implemented the Satterthwaite's method for approximating degrees of freedom for the t and F tests. We have also implemented the construction of Typ...

Purpose The authors sought to determine an optimal set of flesh points on the tongue and lips for classifying speech movements. Method The authors used electromagnetic articulographs (Carstens AG500 and NDI Wave) to record tongue and lip movements from 13 healthy talkers who articulated 8 vowels, 11 consonants, a phonetically balanced set of words, and a set of short phrases during the recording. We used a machine-learning classifier (support-vector machine) to classify the speech stimuli on the...

Maximum likelihood or restricted maximum likelihood (REML) estimates of the parameters in linear mixed-effects models can be determined using the lmer function in the lme4 package for R. As for most model-fitting functions in R, the model is described in an lmer call by a formula, in this case including both fixed- and random-effects terms. The formula and data together determine a numerical representation of the model from which the profiled deviance or the profiled REML criterion can be evalua...

Previous work has shown that velar stops are produced with a forward movement during closure, forming a forward (anterior) loop for a VCV sequence, when the preceding vowels are back or mid. Are listeners aware of this aspect of articulatory dynamics? The current study used articulatory synthesis to examine how such kinematic patterns are reflected in the acoustics, and whether those acoustic patterns elicit different goodness ratings. In Experiment I, the size and direction of loops was modulat...

The purpose of this study is to examine and compare the amount of inter-speaker variability in the articulation of monozygotic twin pairs (MZ), dizygotic twin pairs (DZ), and pairs of unrelated twins with the goal of examining in greater depth the influence of physiology on articulation. Physiological parameters are assumed to be very similar in MZ twin pairs in contrast to DZ twin pairs or unrelated speakers, and it is hypothesized that the speaker specific shape of articulatory looping traject...

We present a novel quantitative model for the generation of articulatory trajectories based on the concept of sequential target approximation. The model was applied for the detailed reproduction of movements in repeated consonant-vowel syllables measured by electromagnetic articulography (EMA). The trajectories for the constrictor (lower lip, tongue tip, or tongue dorsum) and the jaw were reproduced. Thereby, we tested the following hypotheses about invariant properties of articulatory commands:...

The aim of this study was to investigate the supralaryngeal control of the production of the Korean three-way contrast in velar stops. First, an EMA-experiment with three Korean speakers was carried out, and the kinematic properties of the tongue back were analyzed (length of the deceleration phase of the movement, peak velocity, peak acceleration, amplitude and duration of the looping movement during consonantal closure, and angle of incidence between tongue and palate at contact onset). To und...

This paper examines tongue movements between the two vowels in sequences of vowel-labial consonant-vowel, addressing the question whether the movement is a straight line or a curved path. Native speakers of Japanese and Italian served as subjects. The linguistic material consisted of words where the bilabial consonant was either long or short. The inclusion of words with different consonant lengths was motivated by earlier findings that the tongue movement is often longer when the consonant is l...
