The measures showed expected patterns, supporting their validity. Comparison of these data with studies of adults suggests some developmental patterns that call for further study. The measures may also serve to differentiate some cases of typical and misarticulated /s/.
Jaw and Order

It is well-accepted that the jaw plays an active role in influencing vowel height. The general aim of the current study is to further investigate the extent to which the jaw is active in producing consonantal distinctions, with specific focus on coronal consonants. Therefore, tongue tip and jaw positions are compared for the German coronal consonants /s, f, t, d, n, l/, that is, consonants having the same active articulators (apical/laminal) but differing in manner of articulation. In order to test the stability of articulatory positions for each of these coronal consonants, a natural perturbation paradigm was introduced by recording two levels of vocal effort: comfortable, and loud without shouting. Tongue and jaw movements of five speakers of German were recorded by means of EMMA during /aCa/ sequences. By analyzing the tongue tip and jaw positions and their spatial variability we found that (1) the jaw's contribution to these consonants varies with manner of articulation, and (2) for all coronal consonants the positions are stable across loudness conditions except for those of the nasal. Results are discussed with respect to the tasks of the jaw, and the possible articulatory adjustments that may accompany louder speech.

Recent phonological approaches incorporate phonetic principles in the motivation of phonological regularities, e.g. vowel reduction and neutralization in unstressed position by target undershoot. So far, evidence for this hypothesis is based on impressionistic and acoustic data but not on articulatory data. The major goal of this study is to compare formant spaces and lingual positions during the production of German vowels for combined effects of stress, accent and corrective contrast. In order to identify strategies for vowel reduction independent of speaker-specific vocal-tract anatomies and individual biomechanical properties, an approach similar to the Generalized Procrustes Analysis was applied to formant spaces and lingual vowel target positions. The data basis consists of the German stressed and unstressed full vowels /iù ɪ yù ʏ eù ɛ ɛù φ ù œ aù a où ɔ uù ʊ/ from seven speakers recorded by means of electromagnetic midsagittal articulography (EMMA). Speaker normalized articulatory and formant spaces gave evidence for a greater degree of coarticulation with the consonant context for unstressed vowels as compared to stressed vowels. However, only for tense vowels could spatial reduction patterns be attributed to vowel shortening, whereas lax vowels were reduced without shortening. The results are discussed in the light of current theories of vowel reduction, i.e. target undershoot, Adaptive Dispersion Theory and Prominence Alignment.

There is currently a wealth of activity involving the analysis of complex segmental sequences from phonetic, phonological and psycholinguistic perspectives. This volume draws from selected contributions to the conference Consonant Clusters and Structural Complexity held in Munich in August 2008. Consonant sequences, whether occurring within individual lexical items or emerging in running speech at word boundaries, give particularly striking evidence for the temporal complexity of human speech. But contributions also consider the integration of tonal and vocalic elements into syllable structure. The main aim of the volume is to do justice to this complexity by bringing together researchers from a wide range of backgrounds.

If more than one articulator is involved in the execution of a phonetic task, then the individual articulators have to be temporally coordinated with each other in a lawful manner. The present study aims at analyzing tongue-jaw cohesion in the temporal domain for the German coronal consonants [s, f, t, d, n, l], i.e., consonants produced with the same set of articulators--the tongue blade and the jaw--but differing in manner of articulation. The stability of obtained interaction patterns is evaluated by varying the degree of vocal effort: comfortable and loud. Tongue and jaw movements of five speakers of German were recorded by means of electromagnetic midsagittal articulography (EMMA) during [aCa] sequences. The results indicate that (1) tongue-jaw coordination varies with manner of articulation, i.e., a later onset and offset of the jaw target for the stops compared to the fricatives, the nasal and the lateral; (2) the obtained patterns are stable across vocal effort conditions; (3) the sibilants are produced with smaller standard deviations for latencies and target positions; and (4) adjustments to the lower jaw positions during the surrounding vowels in loud speech occur during the closing and opening movement intervals and not the consonantal target phases.

This study uses acoustic and physiological measures to compare laryngeal reflexes of global changes in vocal effort to the effects of modulating such aspects of linguistic prominence as sentence accent, induced by focus variation, and word stress. Seven speakers were recorded by using a laryngograph. The laryngographic pulses were preprocessed to normalize time and amplitude. The laryngographic pulse shape was quantified using open and skewness quotients and also by applying a functional version of the principal component analysis. Acoustic measures included the acoustic open quotient and spectral balance in the vowel /e/ during the test syllable. The open quotient and the laryngographic pulse shape indicated a significantly shorter open phase for loud speech than for soft speech. Similar results were found for lexical stress, suggesting that lexical stress and loud speech are produced with a similar voice source mechanism. Stressed syllables were distinguished from unstressed syllables by their open phase and pulse shape, even in the absence of sentence accent. Evidence for laryngeal involvement in signaling focus, independent of fundamental frequency changes, was not as consistent across speakers. Acoustic results on various spectral balance measures were generally much less consistent compared to results from laryngographic data.

Abstract. Inter-consonantal cohesion in French word-initial CC clusters is investigated in light of recent proposals of gestural coordination. Specifically, the timing of lip and tongue movements of C1/l / and C1/n / productions, with C1 being one of the consonants /p, f, k/, of two speakers were studied using electromagnetic articulography (EMA). In French, C/l / clusters occur frequently in word-initial position, while C/n / sequences have a limited distribution in less common words. The results provide evidence that liquid as well as nasal sequences consistently show the same ‘place of articulation’ effect of gestural overlap as previously reported for stop-stop clusters, with more overlap in front-to-back than back-to-front sequences. This suggests that the effect is partially due to low-level motor constraints rather than considerations of perceptual recoverability. Furthermore, the results show that the lexical frequency of the sequence does not influence the timing in a simple, categorical manner: stop-nasal clusters showed a strikingly different inter-gestural coordination in comparison with their stop-/l / counterparts, while no such differences could be observed for the fricative pair. An additional analysis of the overall C-centre of the CC structures demonstrated a rather high temporal stability suggesting that there is, despite many timing differences emerging at the phonetic surface, a relative constant phasing between initial consonant sequence and following vowel.

Coarticulation and invariance are two topics at the center of theorizing about speech production and speech perception. In this paper, a quantitative scale is proposed that places coarticulation and invariance at the two ends of the scale. This scale is based on physical information flow in the articulatory signal, and uses Information Theory, especially the concept of mutual information, to quantify these central concepts of speech research. Mutual Information measures the amount of physical information shared across phonological units. In the proposed quantitative scale, coarticulation corresponds to greater and invariance to lesser information sharing. The measurement scale is tested by data from three languages: German, Catalan, and English. The relation between the proposed scale and several existing theories of coarticulation is discussed, and implications for existing theories of speech production and perception are presented.

ABSTRACT: The tongue moves in a narrow space which influences the speech planning process and affects the kinematic properties of the movement. In order to study the possible role of tongue-palate interaction we investigated tongue tip movement together with tonguepalatal contact patterns by means of simultaneous EMA and EPG recordings. Articulatory data for four German speakers were analyzed. Speech material consisted of VC and VC@ sequences with C being /t/ or /s/ and V being stressed tense /a/ or /u/. The relation between the kinematics of the tongue tip closing gesture and changes in tongue-palatal contact patterns in the anterior, posterior and lateral region were studied. Results for /t/ show a large movement amplitude and a short closing gesture duration whereas in /s/ production the movement amplitude is smaller and the duration longer than in /t/. We conclude that in /t/ the tongue tip hits the palate and this impact stops the movement. In /s/ production we suppose that a precise positioning of the tongue tip is achieved. Speaker dependent tongue-palatal contact patterns can be explained in terms of differences in the palatal shape.

The tense and lax vowels of German were compared, based on an analysis of the duration, amplitude and velocity characteristics of lip and tongue movement. This study examined firstly whether they show different patterns of compression over changes in speech rate, and secondly whether velocity profiles would reveal evidence of different underlying control mechanisms. CVC movements were segmented into CV, nucleus and VC portions. Speech rate affected duration of CV and VC movements similarly for tense and lax vowels. However, the effect on nucleus duration was vastly greater for the tense vowels. Analysis of the velocity profiles of CV and VC movements in terms of the ratio of peak to average velocity showed no differences between tense and lax vowels, once differences in duration were taken into account. The conclusion is that tense and lax vowels share similar control mechanisms for the elementary CV and VC movements, but differ radically in the way these elements are concatenated. 1.

The effect of palatal contact on tongue tip kinematics was investigated using simultaneous EMMA and EPG recordings. The material consisted of VC sequences, where C is a voiced or voiceless alveolar stop. The kinematic characteristics were studied by analyzing parameters of the velocity profile and the deceleration peaks of the closing gesture. No evidence could be found for a potential influence of lateral contacts. Central contacts, associated with the beginning of the consonantal closure, are strongly correlated in time with the velocity drop. It supports the hypothesis that for achieving a consonantal closure tongue tip kinematics is not controlled by a specific target on the palate, and that its deceleration phase is mostly influenced by the collision with the palate.

ABSTRACT: The aim of the current study is to investigate the contextual conditions of \ndevoicing of phonologically voiced stops. Therefore articulatory and acoustical data of four \nmale speakers were recorded by means of EMMA and EPG. Devoicing was observed more \nfrequently for the velar stops than for the bilabials. The highest occurrence of devoicing was \nobserved when the voiced stop was followed by a low or mid vowel. To test whether \narticulatory positions are affected by the identity of the following vowel ANOVAs were \ncomputed. All subjects showed significant effects on positional data varying with place of \narticulation of the stop. Percentage of devoicing was significantly correlated with vertical and \nhorizontal tongue positions for the velar and with the vertical jaw position for both stops. \nStepwise regression models were computed to achieve an objective measure for the relevance \nof the measured parameters. We assume that in German movement economy, i.e. \ncoarticulation, is more important than the maintenance of voicing during the closure, which is \nin agreement with the view that the voicing distinction in German is primarily produced by a \nlonger VOT for the voiceless stops.

This study investigates the effects of varying prosodic boundary strength and lexical stress on domain initial /kl/ clusters in German by means of Electropalatography (EPG). Recordings of 7 subjects were analyzed using temporal and spatial parameters derived from the EPG data. Temporal and spatial parameters show that boundary effects are stronger for the first consonant while in the temporal domain stress affects the second consonant rather than the first. Overlap was found to be greater in unstressed position and at lower prosodic boundaries. Furthermore, /kl/ appears to be more susceptible to stress effects when not preceded by a boundary.

In Articulatory Phonology the jaw is not controlled individually but serves as an additional articulator to achieve the primary constriction. In this study the timing of jaw and tongue tip gestures for the coronal consonants /s, , t, d, n, l/ is analysed by means of EMMA. The findings suggest that the tasks of the jaw for the fricatives are to provide a second noise source and to stabilise the tongue position (more pronounced for /s/). For the voiceless stop, the speakers seem to aim at a high jaw position for producing a prominent burst. For /l/ a low jaw position is essential for avoiding lateral contact and for the apical articulation of this sound.

One of the goals of phonetic investigations is to find strategies for vowel production independent of speaker-specific vocal-tract anatomies and individual biomechanical properties. In this study techniques for speaker normalization that are derived from Procrustes methods were applied to acoustic and articulatory data. More precisely, data consist of the first two formants and EMMA fleshpoint markers of stressed and unstressed vowels of German from seven speakers in the consonantal context /t/. Main results indicate that (a) for the articulatory data, the normalization can be related to anatomical properties (palate shapes), (b) the recovery of phonemic identity is of comparable quality for acoustic and articulatory data, (c) the procedure outperforms the Lobanov transform in the acoustic domain in terms of phoneme recovery, and (d) this advantage comes at the cost of partly also changing ellipse orientations, which is in accordance with the formulation of the algorithms.

It is not yet standard practice in phonetics to provide access to audio files along with submissions to journals. This is paradoxical in view of the importance of data for phonetic research: from audio signals to the whole range of data acquired in phonetic experiments. The phonetic sciences stand to gain greatly from data availability: what is at stake is no less than reproducibility and cumulative progress. We will argue that a collective turn to Open Science holds great promise for phonetics. First, simple reflections on why access to primary data matters are recapitulated and proposed as a basis for consensus. Next, possible drawbacks of data availability are addressed. Finally, we argue that data curation and archiving are to be recognized as part of the same activity that results in the publication of research papers, rather than attempting to build a parallel system to incentivize data archiving by itself.

Movements of the head and speech articulators have been observed in tandem during an alternating word pair production task driven by an accelerating rate metronome. Word pairs contrasted either onset or coda dissimilarity with same word controls. Results show that as production effort increased, so did speaker head nodding, and that nodding increased abruptly following errors. More errors occurred under faster production rates, and in coda rather than onset alternations. The greatest entrainment between head and articulators was observed at the fastest rate under coda alternation. Neither jaw coupling nor imposed prosodic stress was observed to be a primary driver of head movement. In alternating pairs, nodding frequency tracked the slower alternation rate rather than the syllable rate, interpreted as recruitment of additional degrees of freedom to stabilize the alternation pattern under increasing production rate pressure.

The contributions in this Festschrift were written by Ocke’s current and former PhD-students, colleagues and research collaborators. The Festschrift is divided into six sections, moving from the smallest building blocks of language, through gradually expanding objects of linguistic inquiry to the highest levels of description - all of which have formed a part of Ocke’s career, in connection with his teaching and/or his academic productions: “Segments”, “Perception of Accent”, “Between Sounds and Graphemes”, “Prosody”, “Morphology and Syntax” and “Second Language Acquisition”. Each one of these illustrates a sound approach to language matters.
