A two-week perturbation EMA-experiment was carried out with palatal prostheses. Articulatory effort for five speakers was assessed by means of peak acceleration and jerk during the tongue tip gestures from /t/ towards /i, e, o, y, u/. After a period of no change speakers showed an increase in these values. Towards the end of the experiment the values decreased. The results are interpreted as three phases of carrying out changes in the internal model. At first, the complete production system is shifted in relation to the palatal change, afterwards speakers explore different production mechanisms which involves more articulatory effort. This second phase can be seen as a training phase where several articulatory strategies are explored. In the third phase speakers start to select an optimal movement strategy to produce the sounds so that the values decrease.
Temporal development of compensation strategies for perturbed palate shape in German /S/-production
(2006)
The palate shape of four speakers was changed by a prosthesis which either lowered the palate or retracted the alveoles. Subjects wore the prosthesis for two weeks and were recorded several times via EMA. Results of articulatory measurements show that speakers use different compensation methods at different stages of the adaptation. They lower the tongue immediately after the insertion of the prosthesis. Other compensation methods as for example lip protrusion are only acquired after longer practising periods. The results are interpreted as supporting the existence of different mappings between motor commands, vocal tract shape and auditory-acoustic target.
Several articulatory strategies are available during the production of /u/, all resulting in a similar acoustic output. /u/ has two main constrictions, at the velum and at the lips. A perturbation of either constriction can be compensated at the other one, e.g wider constriction at the velum by more lip protrusion, wider lip opening by more tongue retraction. This study investigates whether speakers use this relation under perturbation. Six 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 negative correlation between lip protrusion and F1 or F2 could sometimes be observed, but no correlation occurred between constriction size and either of the formants. The results show that under perturbation speakers use motor equivalent strategies in order to adapt. The correlation between constriction size and lip protrusion is stronger than in studies investigating unperturbed speech. 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.
Two hypotheses have been proposed in order to account for velar softening, i.e., a process through which /k/ changes to an affricate. Whereas one hypothesis states that for the process to apply the velar stop has to be realized as an (alveolo) palatal stop (articulation-based hypothesis), the other claims that velar softening is triggered by acoustic similarity between the input and output segments (acoustic equivalence hypothesis). The present paper investigates the acoustic equivalence hypothesis by comparing several acoustic properties of /k/ in various vowel contexts with those of /ts , ts , tc / for three languages differing in stop burst aspiration, i.e., German, Polish and Catalan. Results suggest that the acoustic equivalence hypothesis could account for velar softening in aspirated velar stops but not in unaspirated velar stops. The results also provide an explanation as to why aspirated velar stops are prone to undergo softening more easily when followed by front vocalic segments than in other contexts and positions
This paper shows that several typologically unrelated languages share the tendency to avoid voiced sibilant affricates. This tendency is explained by appealing to the phonetic properties of the sounds, and in particular to their aerodynamic characteristics. On the basis of experimental evidence it is shown that conflicting air pressure requirements for maintaining voicing and frication are responsible for the avoidance of voiced affricates. In particular, the air pressure released from the stop phase of the affricate is too high to maintain voicing, which in consequence leads to a devoicing of the frication part.
A model is proposed that interprets a variety of connected speech processes as resulting from prosodic modulations at different tiers of functional speech motor control along the hypo-hyper dimension [10]. The general background of the model is given by the trichotomy of A-, B- and C-prosodic phenomena [15] that together constitute the acoustic makeup of any speech utterance (with regard to their respective time domains at the uttarance/phrase level, the syllabic level and the segmental level).
Bilabial stops undergoing Surface Palatalization (SP) were analyzed in an EMMA/EPG study. Articulatorily, the point of maximal palatal contact and the labial opening movement were analyzed. The acoustic analysis pertained to stop related timing and the point of the highest F2-value. Results show (i) that SP yields a higher F2 at vowel onset and a lengthened opening gesture and (ii) that morphemeinduced palatalizations are distinguished from word initial ones and sandhi-palatalizations articulatorily and acoustically by a shorter delay of palatal target position with respect to stop production; (iii) no differences are found between ‘repalatalized’ and plain segments in case of sandhi palatalization.
Stellen wir uns vor, wir hätten im Jahre 1600 eine wissenschaftliche Kontroverse in deutscher Sprache zu führen, beispielsweise über die Frage, ob die Astrologie eine ernstzunehmende Wissenschaft ist – eine sehr aktuelle Debatte in dieser Zeit. In dieser Lage müssten wir natürlich den damaligen Fachwortschatz der Astronomie und Astrologie beherrschen, wir müssten beispielsweise wissen was eine Coniunction der Planeten Jupiter und Mars oder eine Zusammenfügung Saturni vnnd der Sonnen ist oder wie der Ausdruck newer Stern verwendet wird. Gleichzeitig müssten wir aber auch den nicht-fachspezifischen, allgemeinen wissenschaftlichen Sprachgebrauch der Zeit kennen, der für wissenschaftliche Auseinandersetzungen verwendet wurde. Zumeist wurden Kontroversen zwischen Akademikern in dieser Zeit auf Latein geführt, der wissenschaftlichen lingua franca der Zeit. Wenn aber eine größere deutschsprachige Öffentlichkeit angesprochen werden sollte, wurde auch die deutsche Sprache verwendet, in der – wie ich zeigen möchte – für diesen Zweck schon sehr differenzierte sprachliche Mittel entwickelt waren.
Zur Beschreibung der Dialogdynamik : Plädoyer für eine kommunikationshistorische Betrachtungsweise
(1989)
Bei der Betrachtung längerer Gesprächsverläufe bietet sich uns oft das Bild einer sukzessiven Entfaltung der Dialogzusammenhänge, die teils schrittweise, teils sprunghaft verläuft. Es werden Themen eingeführt, durchgespielt und gewechselt. Manche Bemerkungen eröffnen ganze Zweige des Gesprächs, andere verschließen gewisse Entwicklungsmöglichkeiten, zumindest für eine bestimmte Zeit. Argumentative Passagen mit erhöhtem Anspruch an Strenge der Gedankenführung und Präzision der Redeweise lösen lockere Passagen mit geringer Ernsthaftigkeit ab. Ein Dialog beginnt als Vorwurfskommunikation und endet als allgemeiner Diskurs über die Geltung von Normen. Neue Redeweisen kommen auf, spielen sich ein und werden fallen gelassen. Mißverständnisse treten auf, werden geklärt oder auch nicht. Erst am Schluß eines Gesprächs versteht man so richtig, was der Gesprächspartner am Anfang gemeint hat usw. Derartige Erscheinungen möchte ich unter den Begriff der Dialogdynamik fassen. Eine Betrachtungsweise, die speziell die Entfaltung von Kommunikationszusammenhängen im eben erläuterten Sinne zu erfassen sucht, könnte man kommunikationshistorisch oder kommunikationsdynamisch nennen, je nachdem, ob eher der Verlauf konkreter Kommunikationen unter Aspekten der genannten Art analysiert werden soll oder ob eine systematische Analyse von Typen von Kommunikationsverläufen beabsichtigt ist.
Coherence in hypertext
(1999)
At first sight hypertext does not look !ike a good subject for research on coherence. Hypertext is non-linear text, and coherence is typically defined for linear text. So coherence does not seem to be involved in hypertext at all. But on closer inspection it emerges that some of the basic structural problems with hypertexts are classical problems of coherence.
Our study is concerned with the identification of ‘difficult’ structure s in the acquisition of a foreign language, which will shed light on theoretical considerations of L2 processing. We argue that – compared to simple vocabulary items or abstract syntactic patterns – structures that contain lexical material as well as categorial variables are especially difficult to acquire. The difficulty level for particular patterns is shown to depend on surface invariability but not on the syntactic categories within which target patterns are embedded. As an example we study the distribution of certain structures which are underused by L2 German learners.
Word formation in Distributed Morphology (see Arad 2005, Marantz 2001, Embick 2008): 1. Language has atomic, non-decomposable, elements = roots. 2. Roots combine with the functional vocabulary and build larger elements. 3. Roots are category neutral. They are then categorized by combining with category defining functional heads.
Thema dieses Aufsatzes sind die Methoden der Datenerhebung für syntaktische Untersuchungen und deren Auswirkungen auf die Ergebnisse dieser Untersuchungen. Die Wahl der Datenbasis ist selbst schon bestimmt durch bestimmte theoretische Positionen, Einstellungen gegenüber dem Forschungsgegenstand und durch bestimmte Erkenntnisinteressen. Es soll hier also nicht der Eindruck erweckt werden, als wäre die Datenbasis per se für die "Folgen" verantwortlich.
Redekommentierende Einschübe
(1996)
Das Thema dieses Aufsatzes sind redekommentierende Einschübe. Zunächst gilt es zu klären, was unter "Einschub" verstanden werden soll. Einschub verwende ich hier weitgehend gleichbedeutend mit Parenthese. Parenthesen werden jedoch manchmal als "Schaltsätze", also als eingeschobene Sätze, definiert. Einschub ist hier ein weniger vorbelasteter Terminus.
Valenz und Relevanz - eine informationsstrukturelle Erklärung für "obligatorische" Adverbiale
(1995)
Adverbiale stellen ein Problem fü r die Beschreibung der Valenz bzw. der Argumentstruktur von Verben dar, da sie sowohl als Ergänzungen (Argumente) wie auch als freie Angaben (Adjunkte) auftreten können. Die Obligatorik bietet keine Möglichkeit, Ergänzungen von Angaben zu unterscheiden, da Ergänzungen sowohl obligatorisch als auch fakultativ sein können.
Im folgenden Beitrag werden die Möglichkeiten der Bildung des Progressivs im Aja dargestellt sowie die zur Bildung des Progressivs verwendeten Formen in ihrer Grammatikalisierungskette vorgestellt. Das Aja gehört zu einer Gruppe von Sprachen/Dialekten, die lange Zeit unter dem Begriff "Ewe" zusammengefaßt wurden, in jüngster Zeit aber auch als Gbe(-Kontinuum) bezeichnet werden. Dabei ist "Gbe" ein in allen sprachlichen Einheiten des Kontinuums anzutreffendes Lexem mit der Bedeutung "Sprache".
This article discusses the divergent status of the two particles lé and lá in the grammar of Konkomba, a Gur language (Niger-Congo) of the Gurma subgroup. While previous studies claim that both particles are focus markers, this author argues that only the particle lá should be analyzed as a pure pragmatic device. Distributional studies suggest that the use of particle lé, on the other hand, is only required under specific focus conditions, and primarily represents a syntactic device.

Focus expressions in Yom
(2005)
In our presentation we will outline the verb system of Lelemi and concentrate on certain “focal” aspects which are of primary interest to us. Lelemi has two TAMP paradigms: one constituting the so-called “simple tenses”, the other the so-called “relative tenses” (Allan 1973), although not every “simple tense” has a counterpart in the “relative tenses”. The simple paradigm is formed by subject prefixes (prefixed pronouns for 1st or 2nd person and noun class pronouns for 3rd persons) and the verb form whereas the relative paradigm is build up by the obligatory use of an external subject noun, an invariable verb prefix, and the verb form. While the simple paradigm is used in quite a lot of syntactic environments the relative paradigm only shows up in relative clauses with the subject being the head as well as in subject and sentence focus constructions including questions concerning the subject. We will show some interesting interactions between the grammatical expression of focus and the verb system and sketch the grammaticalisation path of the morpheme nà.
Research on adverbials in sentence-medial position in the North- Ghanaian Gur language Buli suggests that the language offers two divergent slots for adverbials between subject and verb. Special attention is paid to the group of sentence-medial deictic temporal adverbials. While they have the potential to develop into tense markers, this process seems to depend on special information structural conditions.
Focus in Gur and Kwa
(2006)
The project investigates focus phenomena in the two genetically relatedWest African Gur and Kwa language groups of the Niger-Congo phylum. Most of its members are tone languages, they are similar with respect to word order typology (all are SVO languages), but of divergent morphological type (agglutinating Gur versus isolating Kwa).
Focus expressions in Foodo
(2006)
This talk concerns the copula system in Buli, a Ghanaian language which has also been attested in Bahia (Rodrigues 1935, Zwernemann 1968). Special focus will be put on the categorization of two copula-reminiscent elements for which I will propose a discoursepragmatic analysis.
Metaphern bestimmen nicht nur unser alltägliches Leben, etwa wenn wir vom Rad der Geschichte oder der Bühne des Lebens sprechen, sie geben auch nützliche Orientierung in vielen Bereichen der Wissenschaft, von den schwarzen Löchern der Physiker bis zur Computermetapher des Gehirns in der Kognitionswissenschaft. Eine solche Metapher ist auch die Deutung der Sprache als Werkzeug.
The present study poses the question on what phonetic and phonological grounds postalveolar fricatives in Polish can be analyzed as retroflex and whether postalveolar fricatives in other Slavic languages are retroflex as well. Velarization and incompatibility with front vowels are introduced as articulatory criteria for retroflexion, based on crosslinguistic data. According to these criteria, Polish and Russian have retroflex fricatives, whereas Bulgarian and Czech do not. In a phonological representation of these Slavic retroflexes, the necessity of perceptual features is shown. Lastly, it is illustrated that palatalization of retroflex fricatives both in Slavic languages and more generally causes a phonetic and phonological change to a non-retroflex sound.
On the basis of perceptual experiments we show that alveolo-palatal fricatives and palatalized post-alveolars are two separate sounds which are distinguished not only by Polish native speakers but also by German ones. This claim is partly attested by centre of gravity measurements of the two sibilants. In this paper we revise the claim made by Halle & Stevens [1] and Maddieson & Ladefoged [2] that the Polish alveolo-palatal fricatives [˛, ¸] are palatalized postalveolars [SJ, ZJ]. On the basis of perceptual experiments we show that alveolo-palatal fricatives and palatalized post-alveolars are two separate sounds which are distinguished not only by Polish native speakers but also by German ones. This claim is partly attested by centre of gravity measurements of the two sibilants.
Dutch has a three-way contrast in labiodental sounds, which causes problems for native speakers of German in their acquisition of Dutch, since German contrasts only two labiodentals. The present study investigates the perception of the Dutch labiodental fricative system by German L2 learners of Dutch and shows that native Germans with no or little knowledge of the Dutch language categorize the Dutch labiodental voiced fricative and approximant as their native voiced fricative. Advanced learners, however, succeed in acquiring a category for the voiced fricative, illustrating that plasticity in the perception of a second language develops with the amount of exposure to the language.
Experimental data shows that adult learners of an artificial language with a phonotactic restriction learned this restriction better when being trained on word types (e.g. when they were presented with 80 different words twice each) than when being trained on word tokens (e.g. when presented with 40 different words four times each) (Hamann & Ernestus submitted). These findings support Pierrehumbert’s (2003) observation that phonotactic co-occurrence restrictions are formed across lexical entries, since only lexical levels of representation can be sensitive to type frequencies.
A common topic in recent literature on phonology is the question of whether phonological processes and segments are licensed by prosodic position or by perceptual cues. The former is the traditional view, as represented by e.g. Lombardi (1995) and Beckman (1998), and holds that segments occur in specific prosodic positions such as the coda. In a licensing by cue approach, as represented by Steriade (1995, 1999), on the other hand, segments are assumed to occur in those positions only where their perceptual cues are prominent, independent of the prosodic position. In positions where the cues are not salient, neutralization occurs.
Die Orthographie ist ein wichtiger Baustein des Fremdsprachenunterrichts, in der Schreiberwerbsforschung im Fremdsprachenkontext konzentrierte man sich dagegen auf Phänomene der Textgestaltung (z.B. Portman 1991). Es wird eine korpusbasierte Untersuchung von Orthographiefehlern in Texten fortgeschrittener Lernender des Deutschen als Fremdsprache (DaF) vorgestellt. Als Datengrundlage dient das Lernerkorpus Falko (fehlerannotiertes Lernerkorpus), ein Gemeinschaftsprojekt der Freien Universität und der Humboldt Universität Berlin (http://www2.hu-berlin.de/korpling/projekte/falko/FalkoKernBeschreibung.pdf). In diesem Korpus werden sog. Wortschreibungsfehler (vgl. Eisenberg 2004) analysiert werden. Die Untersuchung geht von der Annahme aus, dass sich, abgesehen von direkten Übertragungen, die Beschaffenheit der Orthographie einer Muttersprache (L1) nicht signifikant auf die Lernerorthographie (die Orthographie der Zielsprache) auswirkt. Diese Annahme soll an ausgewählten Wortschreibungsfehlern überprüft werden, so z.B. an fehlerhaften Dehnungs- und Schärfungsmarkierungen englischer DaF-Lernender. Sollte die L1 einen nachweisbaren Einfluss auf die Lernerorthographie haben, so müssten bspw. signifikant mehr Fehler bei der dem Englischen unbekannten Dehnungsgraphie mit Dehnungs-h auftreten als bei der dem Englischen bekannten Schärfungsgraphie mithilfe von Konsonantendopplung im Silbengelenk. Die Ergebnisse der Korpusuntersuchung werden in einem spracherwerbstheoretischen Rahmen diskutiert werden.
Research on a variety of structurally different languages suggests that information is assigned to grammatical form in way of preferred representations of arguments. These preferences can be captured by four interacting constraints which are based on the analysis of spoken and written discourse. These constraints represent measurable discourse preferences: pragmatically unmarked utterances seem to follow them blindly and widely. Consequently, the preferences motivating these constraints seem to represent the default structuring of discourse in immediate relation to elementary grammatical form. Discourse is no longer viewed as acting upon grammatical form, but as being ‘grammatical’ itself.
