• On the relationship between palate shape and articulatory behavior

  2009

  The Journal of the Acoustical Society of America · 92 Zitationen · DOI

  In this study the acoustic and articulatory variabilities of speakers with different palate shapes were compared. Since the cross-sectional area of the vocal tract changes less for a slight change in tongue position if the palate is domeshaped than if it is flat, the acoustic variability should be greater for flat palates than for domeshaped ones. Consequently, it can be hypothesized that speakers with flat palates should reduce their articulatory variability in order to keep the acoustic output constant. This hypothesis was tested on 32 speakers recorded via electropalatography (EPG) and acoustics. The articulatory and acoustic variability of some of their vowels and /j/ was measured. Indeed, the results show that the speakers with flat palates reduce their variability in tongue height. There is no such trend in acoustic variability.

• influence of the palate shape on articulatory token-to-token variability

  2005

  ZAS Papers in Linguistics · 27 Zitationen · DOI

  Articulatory token-to-token variability not only depends on linguistic aspects like the phoneme inventory of a given language but also on speaker specific morphological and motor constraints. As has been noted previously (Perkell (1997), Mooshammer et al. (2004)), speakers with coronally high "domeshaped" palates exhibit more articulatory variability than speakers with coronally low "flat" palates. One explanation for that is based on perception oriented control by the speaker. The influence of articulatory variation on the cross sectional area and consequently on the acoustics should be greater for flat palates than for domeshaped ones. This should force speakers with flat palates to place their tongue very precisely whereas speakers with domeshaped palates might tolerate a greater variability. A second explanation could be a greater amount of lateral linguo-palatal contact for flat palates holding the tongue in position. In this study both hypotheses were tested.
 
 In order to investigate the influence of the palate shape on the variability of the acoustic output a modelling study was carried out. Parallely, an EPG experiment was conducted in order to investigate the relationship between palate shape, articulatory variability and linguo-palatal contact.
 
 Results from the modelling study suggest that the acoustic variability resulting from a certain amount of articulatory variability is higher for flat palates than for domeshaped ones. Results from the EPG experiment with 20 speakers show that (1.) speakers with a flat palate exhibit a very low articulatory variability whereas speakers with a domeshaped palate vary, (2.) there is less articulatory variability if there is lots of linguo-palatal contact and (3.) there is no relationship between the amount of lateral linguo-palatal contact and palate shape. The results suggest that there is a relationship between token-to-token variability and palate shape, however, it is not that the two parameters correlate, but that speakers with a flat palate always have a low variability because of constraints of the variability range of the acoustic output whereas speakers with a domeshaped palate may choose the degree of variability. Since linguo-palatal contact and variability correlate it is assumed that linguo-palatal contact is a means for reducing the articulatory variability.

• Perceptual evidence for allophonic variation of the palatal fricative /ç/ in spontaneous Berlin German.

  2010

  The Journal of the Acoustical Society of America · 20 Zitationen · DOI

  Auer (2004) postulates that the multi-ethnolect Kiezdeutsch (Berlin, Germany) differentiates three realizations of /ɪç/: [ɪç]; [ɪ∫]; [ɪφ]. Acoustic analyzes of 1192 tokens of /ç/ from the ZAS-spontaneous speech database (collected from nine adolescent speakers of the Kiezdeutsch multi-ethnolect as spoken in Berlin) showed no reliable differences in kurtosis, skewness, cog, or peak between items impressionistically categorized into these three groups. Further, in the spontaneous speech of middle-aged monolingual speakers of the local Berlin dialect [∫] variants of /ç/ were also detected, although here this alternation is not attested. The hypotheses are (1) that Berlin-German also has [∫] as an allophonic variant of /ç/ and (2) that Kiezdeutsch has a 3-way-split of this category. To evaluate the perceptual validity of these assumptions, tests are being conducted asking native Berliners to rate the category membership of excised variant realizations of /ç/ and /∫/ from the Kiezdeutsch- and Berlin-database on a scale from 1 (/ç/) to 7 (/∫/), with 4 indicating no real preference for either one. First results point to a two-way perceptual split for the older Berlin speakers and a more fuzzy category boundary between [ç] and [∫] for the Kiez data, suggesting a third intermediate perceptual category.

• Adaptation strategies in perturbed /s/

  2011

  Clinical Linguistics & Phonetics · 16 Zitationen · DOI

  The purpose of this work is to investigate the role of three articulatory parameters (tongue position, jaw position and tongue grooving) in the production of /s/. Six normal speakers' speech was perturbed by a palatal prosthesis. The fricative was recorded acoustically and through electromagnetic articulography in four conditions: (1) unperturbed, (2) perturbed with auditory feedback masked, (3) perturbed with auditory feedback available and (4) perturbed after a 2-week adaptation period. At the end of the adaptation, speakers produced more high-frequency noise while either having a higher jaw position or more grooving of the tongue or both. We discuss the potential clinical implications of the results with regard to the role of jaw height and tongue grooving in the treatment of impaired /s/.

• Inter-speaker articulatory variability during vowel-consonant-vowel sequences in twins and unrelated speakers

  2013

  The Journal of the Acoustical Society of America · 14 Zitationen · DOI

  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 trajectories of the tongue is at least partly dependent on biomechanical properties and the speaker's individual physiology. By means of electromagnetic articulography (EMA), inter-speaker variability in the looping trajectories of the tongue back during /VCV/ sequences is analyzed. Results reveal similar looping patterns within MZ twin pairs but in DZ pairs differences in the shape of the loop, the direction of the upward and downward movement, and the amount of horizontal sliding movement at the palate are found.

• Temporal and spatial aspects concerning the realizations of the voicing contrast in German alveolar and postalveolar fricatives

  2007

  Advances in Speech Language Pathology · 13 Zitationen · DOI

  This study investigates the phonetic realizations of voicing contrast in alveolar and postalveolar fricatives production in different word positions in order to understand the temporal and spatial production strategies used in the control of voicing and frication, and to provide a frame of reference for speech therapy despite the inter-speaker variation. Seven native speakers of German, originally coming from various regions, participated in the experiment. Acoustic signals were recorded onto DAT, and tongue palate contact patterns were recorded by means of electropalatography (EPG). The temporal parameters were measured using the acoustic signals and the spatial parameters were measured based on the EPG data. The corpus included real words with // occurring at word initial, medial and final positions. Temporal results showed that differences in the overall frication duration for voicing contrast occur at almost all positions (with longer duration for voiceless phonemes). However, voicing during the frication interval was a less reliable discriminator, particularly for Southern German speakers and at word final position. We found a positive correlation between the relative voicing duration and the amount of tongue palate contact for subjects who produced voicing. Especially for the postalveolars, voicing also coincides with more front articulation. Results are discussed with respect to laryngeal-oral co-ordination and aerodynamics.

• Motor Equivalent Strategies in the Production of German /∫/ under Perturbation

  2012

  Language and Speech · 8 Zitationen · DOI

  The German sibilant /∫/ is produced with a constriction in the postalveolar region and often with protruded lips. By covarying horizontal lip and tongue position speakers can keep a similar acoustic output even if the articulation varies. This study investigates whether during two weeks of adaptation to an artificial palate speakers covary these two articulatory parameters, whether tactile landmarks have an influence on the covariation and to what extent speakers can foresee the acoustic result of the covariation without auditory feedback. Six German speakers were recorded with EMA. Four of them showed a covariation of lip and tongue, which is consistent with the motor equivalence hypothesis. The acoustic output, however, does not stay entirely constant but varies with the tongue position. The role of tactile landmarks is negligible. To a certain extent, speakers are able to adapt even without auditory feedback.

• The Effect of Inferences on the Perceptual Categorization of Berlin German Fricatives.

  2011

  ICPhS · 8 Zitationen

  In Berlin German, the identification of /c/ as in Fichte ‘spruce’ versus the alveopalatal fricative /ʃ/ in fischte (3. sg. past tense) ‘to fish’ is influenced by what neighborhood in Berlin hearers believe a speaker comes from (KB: Kreuzberg: multi-ethnic, multi-cultural or ZD: Zehlendorf: mono-ethnic, upscale, affluent area) and the inferences made as to how the speaker is likely to realize these two variants. Our results indicate that listeners adjust their interpretation of synthesized acoustic continua in accordance with their expectation, strongly suggesting that both perceptual cues and inferred social factors play a role in the categorization of speech stimuli. Thus, the results show that the mere suggestion of where the speaker may come from even within the confines of a city is enough to trigger such inferences.

• Mechanisms of contrasting Korean velar stops: a catalogue of acoustic and articulatory parameters

  2003

  ZAS Papers in Linguistics · 6 Zitationen · DOI

  The Korean stop system exhibits a three-way distinction in velar stops among /g/, /k'/ and /kh/. If the differentiation is regarded as being based on voicing, such a system is rather unusual because even a two-way distinction between a voiced and a voicless unaspirated velar stop gets easily lost in the languages of the world especially in the case of velar stops. One possibility for maintainig this distinction is that supralaryngeal characteristics like articulators' velocity, duration of surrounding vowels or stop closure duration are involved. The aim of the present study is to set up a catalogue of parameters which are involved in the distinction of Korean velar stops in intervocalic position.
 
 Two Korean speakers have been recorded via Electromagnetic Articulography. The word material consisted of VCV-sequences where V is one of the three vowels /a/, /i/ or /u/ and C one of the Korean velars /g/, /k'/ or /kh/. Articulatory and acoustic signals have been analysed It turned out that the distinction is only partly built on laryngeal parameters and that supralaryngeal characteristics differ for the three stops. Another result is that the voicing contrast is not a matter of one parameter, but there is always a set of parameters involved. Furthermore, speakers seem to have a certain freedom in the choice of these parameters.

• The influence of coarticulatory and phonemic relations on individual compensatory formant production

  2019

  The Journal of the Acoustical Society of America · 3 Zitationen · DOI

  Previous auditory perturbation studies have shown that speakers are able to simultaneously use multiple compensatory strategies to produce a certain acoustic target. In the case of formant perturbation, these findings were obtained examining the compensatory production for low vowels /ɛ/ and /æ/. This raises some controversy as more recent research suggests that the contribution of the somatosensory feedback to the production of vowels might differ across phonemes. In particular, the compensatory magnitude to auditory perturbations is expected to be weaker for high vowels compared to low vowels since the former are characterized by larger linguopalatal contact. To investigate this hypothesis, this paper conducted a bidirectional auditory perturbation study in which F2 of the high central vowel /ɨ/ was perturbed in opposing directions depending on the preceding consonant (alveolar vs velar). The consonants were chosen such that speakers' usual coarticulatory patterns were either compatible or incompatible with the required compensatory strategy. The results demonstrate that speakers were able to compensate for applied perturbations even if speakers' compensatory movements resulted in unusual coarticulatory configurations. However, the results also suggest that individual compensatory patterns were influenced by additional perceptual factors attributable to the phonemic space surrounding the target vowel /ɨ/.

• Motor equivalent strategies in the production of /u/ in perturbed speech

  2008

  The Journal of the Acoustical Society of America · 3 Zitationen · DOI

  Several articulatory strategies are available during the production of /u/, all resulting in a similar acoustic output. For example, speakers can protrude the lips and compensate for that by widening the velar constriction. This study investigates whether speakers use this relation under perturbation. Five speakers were provided with palatal prostheses which were worn for two weeks. Speakers were instructed to make a serious attempt to produce normal speech. Their speech was recorded via EMA and acoustics several times over the adaptation period. Formant values of /u/-productions were measured. Velar constriction width and lip protrusion were estimated. For four speakers a correlation between constriction width and lip protrusion was found. A correlation between lip protrusion and F1 or F2 was rare and no correlation occurred between constriction size and either of the formants. The acoustic output was thus constant. The results show that under perturbation speakers use motor equivalent strategies. The correlation between constriction size and lip protrusion is stronger than in studies investigating unperturbed speech (e.g., Perkell et al., 1993). This could be because under perturbation speakers are inclined to try out several strategies in order to reach the acoustic target and the co-variability might thus be greater.

• Supralaryngeal mechanisms of the voicing contrast in velars

  2005

  ZAS Papers in Linguistics · 3 Zitationen · DOI

  This study investigates supralaryngeal mechanisms of the two way voicing contrast among German velar stops and the three way contrast among Korean velar stops, both in intervocalic position. Articulatory data won via electromagnetic articulography of three Korean speakers and acoustic recordings of three Korean and three German speakers are analysed. It was found that in both languages the voicing contrast is created by more than one mechanism. However, one can say that for Korean velar stops in intervocalic position stop closure duration is the most important parameter. For German it is closure voicing. The results support the phonological description proposed by Kohler (1984).

• Correlation between angle of incidence and sliding patterns of the tongue along the palate in Korean velar stops

  2004

  The Journal of the Acoustical Society of America · 3 Zitationen · DOI

  In former studies, it has been hypothesized that the articulatory production of oral stops could result from the interaction between the tongue moving towards a virtual target located above the palate, and the palate. Velar stops, where the tongue slides along the palate during the occlusion phase, offer a nice experimental framework for further experimental assessments. Indeed, in the framework of the ‘‘virtual target’’ hypothesis, the sliding movement should be seen as the continuation of the movement before the occlusion, but constrained by the palate. Hence, relations should exist between the movement characteristics before contact and during the occlusion phase. To test this hypothesis three Korean speakers were recorded via EMA producing /aCV/ sequences with C=/g/, /k’/ and /kh/, V=/a/, /i/ or /u/. The angle between tongue trajectory just before the impact and palatal contour was estimated, and the amplitude of the sliding movement was measured. Preliminary results for two speakers show that these two variables correlate: The greater the angle, the larger the sliding movement. These findings are interpreted as supporting the ‘‘virtual target’’ hypothesis. This interpretation will be verified by simulations using a 2D biomechanical tongue model [Payan and Perrier, Speech Commun. 22 (1997)].

• Dependency of compensatory strategies on the shape of the vocal tract during speech perturbed with an artificial palate

  2010

  Proceedings of meetings on acoustics · 2 Zitationen · DOI

  This study explores the idea that a speaker's choice of a strategy to compensate for a vocal-tract perturbation depends on the shape of the perturbed vocal tract. Speakers' palatal shapes were perturbed with palatal prostheses. Three speakers used an alveolar prosthesis that effectively moved the alveolar ridge toward the back; three used a central prosthesis that effectively flattened the palate. We hypothesized that during production of the front-rounded vowel /y/ the speakers with the alveolar prosthesis would compensate for the shortened anterior cavity with increased lip protrusion. Lip and tongue movement data from EMA recordings of the speakers' adaptive behavior supported the hypothesis: those whose front cavity was shortened by the palatal prosthesis increased lip protrusion; those with a flattened palate did not. This difference in adaptation strategies was investigated further using simulations with the DIVA model of speech production. The model's vocal tract was adapted to fit two of the speakers' vocal tracts (one with each type of prosthesis), using vocal-tract shape data from structural MRI recordings. Simulations of the model agree with the experimental results: compensation for the alveolar prosthesis was accomplished mainly with lip protrusion, whereas with the central prosthesis, it was accomplished with tongue movement.
