(Non)retroflexivity of slavic affricates and its motivation : Evidence from polish and czech <č>
(2005)
The goal of this paper is two-fold. First, it revises the common assumption that the affricate <č> denotes /t͡ʃ/ for all Slavic languages. On the basis of experimental results it is shown that Slavic <č> stands for two sounds: /t͡ʃ/ as e.g. in Czech and /ʈʂ/ as in Polish.
The second goal of the paper is to show that this difference is not accidental but it is motivated by perceptual relations among sibilants. In Polish, /t͡ʃ/ changed to /ʈʂ/ thus lowering its sibilant tonality and creating a better perceptual distance to /tɕ/, whereas in Czech /t͡ʃ/ did not turn to /ʈʂ/, as the former displayed sufficient perceptual distance to the only affricate present in the inventory, namely, the alveolar /t͡s/. Finally, an analysis of Czech and Polish affricate inventories is offered.
Language planning for the Irish language in the Republic of Ireland has featured prominently in international language policy and planning literature over the years. Researchers in the field may not be up to date, however, with recent developments in the area of Irish language planning and their impact on the language ecology. This monograph describes the language planning situation in the Republic of Ireland in its historical and social contexts as well as delineating language policy and planning for the Irish language implemented over the past number of years, showing developments in education, community, media, religion and local politics.
Man kann die Menschheit in zwei Gruppen teilen: in solche, die sich an fremden Orten verbal anschmiegen und die lokale Sprache in sich aufnehmen als wäre es schon immer die eigene gewesen und solche, die ihre Sprache an einem fremden Ort beibehalten und sich kaum merklich oder gar nicht von ihrer neuen Umgebung sprachlich beeinflussen lassen. Daher fällt einem meist auf, ob jemand beispielsweise in Solothurn seinen Berner, Basler oder Thurgauer Dialekt beibehalten hat, oder aber man beobachtet – vielleicht sodann mit einer gewissen Skepsis –, dass ein zugezogener Mensch das Solothurnische langsam annimmt und seinen eigenen Dialekt nach und nach zu verlernen scheint. ...
In this paper, we present the Multiple Annotation approach, which solves two problems: the problem of annotating overlapping structures, and the problem that occurs when documents should be annotated according to different, possibly heterogeneous tag sets. This approach has many advantages: it is based on XML, the modeling of alternative annotations is possible, each level can be viewed separately, and new levels can be added at any time. The files can be regarded as an interrelated unit, with the text serving as the implicit link. Two representations of the information contained in the multiple files (one in Prolog and one in XML) are described. These representations serve as a base for several applications.
This paper presents the results of Open Quotient measurements in EGG signals of young (18 to 30 year old) and elderly (59 to 82 year old) male and female speakers. The paper further presents quantitative results on the relation between the OQ and the perception of a speaker's age. Higgins & Saxman (1991) found a decreased OQEGG with increasing age for females, whereas the OQEGG in sustained vowel material increased for males as the speakers age increased. In Linville (2002), however, the spectral amplitudes in the region of F0 (obtained by LTAS-measurements of read speech material) increased with increasing age independent of gender; this could be interpreted indirectly as an increasing OQ. We measured the OQEGG not only for sustained vowels, but also in vowels taken from isolated words. In order to analyse the relation between breathiness in terms of an increased OQ and the mean perceived age per stimulus a perception test was carried out in which listeners were asked to estimate speaker's age based on sustained /a/-vowel stimuli varying in vocal effort (soft - normal - loud) during production. The results indicated the following: (i) The decreased OQ for elderly females originally found by Higgins & Saxman is not apparent in our data for sustained /a/-vowels. For our female speakers no significant difference between the OQ of young and old speakers was found; for elderly males, however, we also found an increasing OQ with increasing age.(ii) In addition, a statistically significant increased OQEGG occurs for the group of the elderly males for the vowels from the word material. (iii) Our results show a strong positive relation between perceived age and OQ in male voices. Regarding (i) and (ii), at least the male speaker's voice becomes more breathy as age increases. Considering (iii), increased breathiness may contribute to the listener’s perception of increased age.
This paper discusses constructions like “We’ll have two beers and a coffee.” that are typically used for beverage orders in restaurant contexts. We compare the behaviour of nouns in these constructions in three Germanic languages, English, Icelandic, and German, and take a closer look at the correlation of the morpho-syntactic and semantic-conceptual changes involved here. We show that even within such a closely related linguistic sample, one finds three different grammatical options for the expression of the same conceptual transition. Our findings suggest an analysis of coercion as a genuinely semantic phenomenon, a phenomenon that is located on a level of semantic representations that serves as an interface between the conceptual and the grammatical system and takes into account inter- and intralinguistic variations.
Elke Kasimir´s paper (in this volume) argues against employing the notion of Givenness in the explanation of accent assignment. I will claim that the arguments against Givenness put forward by Kasimir are inconclusive because they beg the question of the role of Givenness. It is concluded that, more generally, arguments against Givenness as a diagnostic for information structural partitions should not be accepted offhand, since the notion of Givenness of discourse referents is (a) theoretically simple, (b) readily observable and quantifiable, and (c) bears cognitive significance.
Ziel des Teilprojekts ist die thematische Erschließung der Korpora, um sowohl themenspezifische virtuelle Subkorpora zusammenstellen zu können als auch aufgrund der Analyse sachgebietsbezogener Häufigkeitsverteilungen z.B. Lesarten disambiguieren zu können. Ausgangspunkt ist die Erstellung einer Taxonomie von Sachgebietsthemen. Dies erfolgt in einem semiautomatischen Verfahren, welches die Anwendung von Textmining (Dokumentclustering) und die manuelle Zuordnung von Clustern in eine externen Ontologie beinhaltet. Es wird argumentiert, dass die so gewonnene Taxonomie sowohl intuitiver als auch objektiver ist als bestehende, rein manuelle Ansätze. Sie eignet sich zudem gleichermaßen für manuelle als auch für maschinelle Klassifikation. Für letzteres wird der Naive Bayes'sche Textklassifikator motiviert und für ein klassifiziertes Korpus von knapp zwei Milliarden Wörtern evaluiert.
This paper describes the creation and preparation of TUSNELDA, a collection of corpus data built for linguistic research. This collection contains a number of linguistically annotated corpora which differ in various aspects such as language, text sorts / data types, encoded annotation levels, and linguistic theories underlying the annotation. The paper focuses on this variation on the one hand and the way how these heterogeneous data are integrated into one resource on the other hand.
When a statistical parser is trained on one treebank, one usually tests it on another portion of the same treebank, partly due to the fact that a comparable annotation format is needed for testing. But the user of a parser may not be interested in parsing sentences from the same newspaper all over, or even wants syntactic annotations for a slightly different text type. Gildea (2001) for instance found that a parser trained on the WSJ portion of the Penn Treebank performs less well on the Brown corpus (the subset that is available in the PTB bracketing format) than a parser that has been trained only on the Brown corpus, although the latter one has only half as many sentences as the former. Additionally, a parser trained on both the WSJ and Brown corpora performs less well on the Brown corpus than on the WSJ one. This leads us to the following questions that we would like to address in this paper: - Is there a difference in usefulness of techniques that are used to improve parser performance between the same-corpus and the different-corpus case? - Are different types of parsers (rule-based and statistical) equally sensitive to corpus variation? To achieve this, we compared the quality of the parses of a hand-crafted constraint-based parser and a statistical PCFG-based parser that was trained on a treebank of German newspaper text.
Tagging kausaler Relationen
(2005)
In dieser Diplomarbeit geht es um kausale Beziehungen zwischen Ereignissen und Erklärungsbeziehungen zwischen Ereignissen, bei denen kausale Relationen eine wichtige Rolle spielen. Nachdem zeitliche Relationen einerseits ihrer einfacheren Formalisierbarkeit und andererseits ihrer gut sichtbaren Rolle in der Grammatik (Tempus und Aspekt, zeitliche Konjunktionen) wegen in jüngerer Zeit stärker im Mittelpunkt des Interesses standen, soll hier argumentiert werden, dass kausale Beziehungen und die Erklärungen, die sie ermöglichen, eine wichtigere Rolle im Kohärenzgefüge des Textes spielen. Im Gegensatz zu “tiefen” Verfahren, die auf einer detaillierten semantischen Repr¨asentation des Textes aufsetzen und infolgedessen für unrestringierten Text m. E. nicht geeignet sind, wird hier untersucht, wie man dieses Ziel erreichen kann, ohne sich auf eine aufwändig konstruierte Wissensbasis verlassen zu müssen.
Theories of cognition that are based on information processing and representation are reactive (Rosen, 1985) or backwards looking, not anticipatory. In a previous article (Thibault, 2005a), I looked at the reasons why humans and bonobos do not need an innate language faculty in order to be minded, languaging beings. The present article takes up some of the questions explored there, but, it asks, on the other hand, what sort of a minded agent has language and what kind of account of language and more broadly meaning do we need to explain minded, languaged agents and the activities they participate in? Following Rosen (1985), I also take up and further develop a point first raised in Thibault (2004a: 187) on language as an anticipatory system, rather than a reactively ‘representational’ one (see also Bickhard, 2005).
The purpose of this article is to report on the work carried out during the research project "O trabalho de tradutor como fonte para a constituição de base de dados" (The translator´s work as a source for the constitution of a database). Through the restoration, organization and digitalization of the personal glossary and part of the books containing the translations made by the deceased public translator Gustavo Lohnefink, this research project intends to construct a digital database of German – Portuguese technical terms (for the language pair), which could then be used by other translators. In order to achieve this purpose, a specific methodology had to be developed, which could be used as a starting-point for the treatment and recovery of other similarly organized data-collections.
We present a system for the linguistic exploration and analysis of lexical cohesion in English texts. Using an electronic thesaurus-like resource, Princeton WordNet, and the Brown Corpus of English, we have implemented a process of annotating text with lexical chains and a graphical user interface for inspection of the annotated text. We describe the system and report on some sample linguistic analyses carried out using the combined thesaurus-corpus resource.
[D]ie polnischen Familiennamen [unterlagen] bis ins 19. Jahrhundert hinein nur geringer amtlicher Kontrolle [...]. Diese Situation begünstigte den sukzessiven Aufbau onymischer Allomorphik aus den […] Flexions- und Derivationsmorphemen, die ursprünglich zur Bildung von Herkunftsbezeichnungen, Patronymika und Übernamen angewendet wurden. Die sekundäre Nutzung dieser Flexions- und Wortbildungsmorpheme als onymische Suffixe trieb den […] Dissoziationsprozess der Familiennamen voran. Die wachsende Produktivität dieser onymischen Morphe, die bis heute andauert, sicherte ihnen die Spitzenposition unter den Proprialitätsmarkern im polnischen Familiennamensystem. Heute sind die onymischen Allomorphe -ska, -ski, -icz, -ak das wichtigste Mittel, mit dem die Zugehörigkeit eines Wortes zum Onomastikon gekennzeichnet wird. […] In diesem Beitrag werden die Entstehungswege und die Ausbreitungspfade der drei produktivsten Gruppen der polnischen onymischen Suffixe präsentiert. Es werden auch die außersprachlichen Faktoren berücksichtigt, die die Erhöhung der Produktivität durch sukzessive Erweiterung der Kombinationsmöglichkeiten der einzelnen Suffixe ermöglicht haben. Es wird gezeigt, dass die ursprünglichen Selektionsbeschränkungen der Basen mit den Suffixen (Toponyme + -ska-Suffixe, Appellative und Adjektive + k-haltige Suffixe, Vornamen + -icz-Suffixe) im Zuge ihrer Ausbreitung und Festigung aufgegeben wurden. Die onymischen Allomorphe sind heute frei kombinierbar und können im Falle des Namenwechsels zur Bildung eines neuen Namens herangezogen werden.
This paper discusses the use of XSLT stylesheets as a filtering mechanism for refining the results of user queries on treebanks. The discussion is within the context of the TIGER treebank, the associated search engine and query language, but the general ideas can apply to any search engine for XML-encoded treebanks. It will be shown that important classes of linguistic phenomena can be accessed by applying relatively simple XSLT templates to the output of a query, effectively simulating the universal quantifier for a subset of the query language.
Wer sich einmal in Deutschschweizer IRC-Chatkanälen herumgesehen hat, hat sofort bemerkt, dass neben der Standardsprache häufig Mundart verwendet wird. Eine Analyse der Varietätenverwendung bietet sich an. Es stellt sich die Frage: was bedeutet sprachliche Norm in einem Kommunikationsraum, in dem die Vorgabe, Deutsch zu schreiben, nur heißt nicht Französisch, Italienisch, Türkisch, Serbisch, Portugiesisch usw. zu schreiben, wo also die Standardsprache nur eine der akzeptierten Varietäten ist? Was bedeutet sprachliche Norm, wo Berndeutsch mit /l/-Vokalisierung neben Walliserdeutsch mit archaischen Volltonvokalen in Nebensilben vorkommt, wo für ein standardsprachliches [a:] ‹a, ah, aa, o, oh› oder ‹oo› stehen kann? Der Frage nach einer deskriptiven Norm wird hier nachgegangen, indem Möglichkeiten der Verschriftung einzelner Aspekte aufgezeigt werden und deren Nutzung in regionalen und überregionalen Chaträumen verglichen werden. Aus dem aktuellen Gebrauch wird dann versucht implizite Normen abzuleiten.
In der deutschsprachigen Schweiz stehen sich gesprochene Mundarten und geschriebene Standardsprache gegenüber. Außer in formellen Situationen wird Mundart gesprochen, und bis vor kurzem wurde nur selten Mundart geschrieben, sondern die hochdeutsche Schriftsprache. Die Chat-Kommunikation zeigt einerseits durch die nicht-zeitversetzte quasi-direkte Kommunikation wesentliche Züge von Mündlichkeit, die zusammen mit der Informalität im Chat den Mundartgebrauch fördert. Andererseits ist das Medium immer noch die Schrift, welche die Domäne der Standardsprache darstellt. Mundart und Standardsprache stehen sich also in Chaträumen in direkter Konkurrenz gegenüber. Der folgende Beitrag analysiert quantitativ und qualitativ das Neben- und Miteinander der beiden Varietäten in Schweizer Chaträumen und untersucht das Vorkommen und die Bedingungen von Code-Alternation und Code-Switches.
In regionalen Schweizer Chaträumen stellt die Mundart mit Anteilen um 80% bis 90% die unmarkierte Varietät dar. Chats bieten somit einen Einblick in die individuell geprägte Verschriftung der Schweizer Dialekte, die sich einerseits regional verschieden präsentiert und andererseits fern von Vereinheitlichungstendenzen liegt. Durch diese Normierungsferne lässt sich aus den Chatdaten in groben Zügen eine Sprachgeographie nachzeichnen, wie sie im Sprachatlas der deutschen Schweiz SDS (1962–1997) festgehalten ist. Hier sollen Reflexe der sprachgeographischen Verteilung in der Verschriftung der flektierten Formen von «haben» nachgezeichnet werden. Neben der grundsätzlichen Bestätigung dieser Struktur zeigen sich in der Analyse auch systematisch Abweichungen, die unter Berücksichtigung der Verschriftungsbarriere Hinweise auf Sprachwandel geben können, die jedoch mit authentischen Daten gesprochener Sprache überprüft werden müssen.
Die Prosodie der Mundarten wurde schon früh als auffälliges und distinktes Merkmal wahrgenommen und in mehreren Arbeiten zur Grammatik des Schweizerdeutschen mittels Musiknoten festgehalten (u. a. J. Vetsch 1910, E. Wipf 1910, K. Schmid 1915, W. Clauss 1927, A. Weber 1948), wobei schon A. Weber (1948, S. 53) anmerkt, "dass sich der musikalische Gang der Rede nicht ohne Gewaltsamkeit mit der üblichen Notenschrift darstellen lässt". Da also eine adäquate Kodierung, eine theoretische Grundlage und die notwendigen phonetischen Instrumente zur Intonationsforschung fehlten, wurden diese ersten Ansätze nicht aus- und weitergeführt. Erst in der Mitte des 20. Jahrhunderts brachte die technische Entwicklung Instrumente zur Messung der Prosodie hervor, die nun durch die Popularisierung der entsprechenden Computerprogramme im Übergang zum 21. Jahrhundert für die linguistische Forschung intensiv und breit genutzt werden können.
This paper describes the processing of MRI and CT images needed for developing a 3D linear articulatory model of velum. The 3D surface that defines each organ constitutive of the vocal and nasal tracts is extracted from MRI and CT images recorded on a subject uttering a corpus of artificially sustained French vowels and consonants. First, the 2D contours of the organs have been manually extracted from the corresponding images, expanded into 3D contours, and aligned in a common 3D coordinate system. Then, for each organ, a generic mesh has been chosen and fitted by elastic deformation to each of the 46 3D shapes of the corpus. This has finally resulted in a set of organ surfaces sampled with the same number of 3D vertices for each articulation, which is appropriate for Principal Component Analysis or linear decomposition. The analysis of these data has uncovered two main uncorrelated articulatory degrees of freedom for the velum's movement. The associated parameters are used to control the model. We have in particular investigated the question of a possible correlation between jaw / tongue and velum's movement and have not find more correlation than the one found in the corpus.
A fundamental question in the study of speech is about the invariance of the ultimate percepts, or features. The present paper gives an overview of the noninvariance problem and offers some hints towards a solution. Examination of various data on place and voicing perception suggests the following points. Features correspond to natural boundaries between sounds, which are included in the infant's predispositions for speech perception. Adult percepts arise from couplings and contextual interactions between features. Both couplings and interactions contribute to invariance. But this is at the expense of profound qualitative changes in perceptual boundaries implying that features are neither independently nor invariantly perceived. The question then is to understand the principles which guide feature couplings and interactions during perceptual development. The answer might reside in the fact that: (1) adult boundaries converge to a single point of the perceptual space, suggesting a context-free central reference; (2) this point corresponds to the neutral vocoïd, suggesting the reference is related to production; (3) at this point perceptual boundaries correspond to the natural ones, suggesting the reference is anchored in predispositions for feature perception. In sum, perceptual invariance seems to be grounded on a radial representation of the vocal tract around a singular point at which boundaries are context-fee, natural and coincide with the neutral vocoïd.
The present study examines native and nonnative perceptual processing of semantic information conveyed by prosodic prominence. Five groups of German learners of English each listened to one of 5 experimental conditions. Three conditions differed in place of focus accent in the sentence and two conditions were with spliced stimuli. The experiment condition was presented first in the learners’ L1 (German) and then in a similar set in the L2 (English). The effect of the accent condition and of the length and position of the target in the sentence was evaluated in a probe recognition task. In both the L1 and L2 tasks there was no significant effect in any of the five focus conditions. Target position and target word length had an effect in the L1 task. Word length did not affect accuracy rates in the L2 task. For probe recognition in the L2, word length and the position of the target interacted with the focus condition.
Plural semantics for natural language understanding : a computational proof-theoretic approach
(2005)
The semantics of natural language plurals poses a number of intricate problems – both from a formal and a computational perspective. In this thesis I investigate problems of representing, disambiguating and reasoning with plurals from a computational perspective. The work defines a computationally suitable representation for important plural constructions, proposes a tractable resolution algorithm for semantic plural ambiguities, and integrates an automatic reasoning component for plurals. My solution combines insights from formal semantics, computational linguistics and automated theorem proving and is based on the following main ideas. Whereas many existing approaches to plural semantics work on a model-theoretic basis using higher-order representation languages I propose a proof-theoretic approach to plural semantics based on a flat firstorder semantic representation language thus showing that a trade-off between expressive power and logical tractability can be found. The problem of automatic disambiguation of plurals is tackled by a deliberate decision to drastically reduce recourse to contextual knowledge for disambiguation but rely instead on structurally available and thus computationally manageable information. A further central aspect of the solution lies in carefully drawing the borderline between real ambiguity and mere indeterminacy in the interpretation of plural noun phrases. As a practical result of my computational proof-theoretic approach to plural semantics I can use my methods to perform automated reasoning with plurals by applying advanced firstorder theorem provers and model-generators available off-the shelf. The results are prototypically implemented within the two logic-oriented natural language understanding applications DRoPs and Attempto. DRoPs provides an automatic plural disambiguation component for uncontrolled natural language whereas Attempto works with a constructive disambiguation strategy for controlled natural language. Both systems provide tools for the automated analysis of technical texts allowing users for example to automatically detect inconsistencies, to perform question answering, to check whether a conjecture follows from a text or to find equivalences and redundancies.
The article presents an analysis of different speech styles used by participants of the German speech community in contrast to the Brazilian one, based on examples of interviews made in both cultures. After the illustration of the different language uses, the article’s focus will be on the communicative functions the styles in each community. So, we find the phatic, poetic and expressive function more dominant in the Brazilian speech, whereas the use of the referential and the metalinguistic function seem to be more common in the speech of the German respondents. It is therefore possible to establish the dichotomy between the actor and the spectator in a metaphorical sense to summarize these contrasting functions. Finally, the fact in which these results can in part be explicated by their embedding in different cultural and historical backgrounds, emphasizing the Brazilian speech community as a more heterogenous and baroque, compared with the German one which tends to be more homogenous and (self)-observing will be shown.
Woher kommt das neuerwachte Interesse an Sprachrichtigkeit? Woher kommt die ausgeprägte sprachliche Unsicherheit, die auch bei vielen hochgebildeten Menschen den Wunsch entstehen lässt, von Sprachpflegern über ihr Ureigenstes, nämlich ihre Muttersprache, belehrt zu werden? Obwohl Antworten auf diese Fragen letztlich spekulativ bleiben, wage ich doch die These, dass eine Ursache hierfür die Rechtschreibreform ist, die von einem Großteil der Bevölkerung nach wie vor nicht angenommen wird, die insgesamt weder zur Vereinfachung noch zu einer höheren Einheitlichkeit geführt hat; die aber andererseits ein öffentliches Nachdenken und Diskutieren über Sprachrichtigkeit in Gang setzte. – Jedenfalls ist die Verunsicherung ein Faktum, das von Linguisten nicht ignoriert werden sollte.
Ausgangspunkt: Die Kritik am "Zwei-Welten-Modell": Die grundlegende linguistische Unterscheidung zwischen "Sprache" und "Sprechen" ist im Rahmen der neueren Debatten um Sprachmedialität wieder verstärkt thematisiert und kritisiert worden. Lässt sich dieses schulbildende, in der Linguistik geradezu eherne Begriffspaar überhaupt noch sinnvollerweise aufrechterhalten? Oder muss es mindestens umdefiniert, vielleicht sogar gänzlich verworfen werden? Hat sich insbesondere die auf Chomsky zurückgehende Unterscheidung von Sprachkompetenz und -performanz nicht von selbst ad absurdum geführt, nachdem der linguistische Kognitivismus chomskyscher Provenienz Sprache als lebendiges Phänomen, als Medium menschlicher Kommunikation, vollständig aus dem Blick verloren hat? Führt nicht schon die scheinbar harmlose linguistische Differenzierung zwischen einer Sprachregel und ihrer Anwendung zu einer irreführenden und unangemessenen Verdinglichung von Sprache? ...
In diesem Aufsatz geht es um die Datenbank ‚Mehrsprachigkeit’ und das System EXMARaLDA, die am SFB 538 ‚Mehrsprachigkeit’ der Universität Hamburg entwickelt werden. Da deren konzeptuelle und technische Details bereits an anderer Stelle ausführlich dargestellt worden sind (z.B. Schmidt 2004), soll der Schwerpunkt hier einerseits auf solchen Aspekten liegen, die – gemäß dem Thema des Workshops – mit allgemeineren Fragen zum Umgang mit computerverwertbaren, heterogenen linguistischen Datenbeständen zu tun haben. Andererseits soll versucht werden, aus den praktischen Erfahrungen der nunmehr vierjährigen Projektarbeit einige Erkenntnisse abzuleiten, die über den konkreten Projektzusammenhang hinaus für die weitere Arbeit auf diesem Gebiet interessant sein könnten.
This paper advances a purely presuppositional analysis of intonation. I first show that a inspiring recent article by Geurts and van der Sandt (Theoretical Linguistics, 2004) that pursues the same goal cannot account for multiple foci. Then, I show that if it is assumed that destressed rather than focussed material is semantically marked, multiple foci are accounted for correctly.
DP is not a scope island

The epistemic step
(2005)
This paper provides an analysis of an alternative strategy to A´-movement in both German and Dutch where the extracted constituent is preceded by a preposition and a coreferential pronoun appears in the extraction site. The construction has properties of both binding and movement: Whereas reconstruction effects suggest movement out of the embedded clause, there is strong evidence that the operator constituent is linked to an A-position in the matrix clause; this paradox is resolved by assuming a Control-like approach that involves movement from the embedded clause into a theta-position in the matrix clause with subsequent short A´- movement. The coreferential pronoun is interpreted as a resumptive heading a Big-DP which hosts the antecedent in its specifier.
This paper contributes to the understanding of vocal folds oscillation during phonation. In order to test theoretical models of phonation, a new experimental set-up using a deformable vocal folds replica is presented. The replica is shown to be able to produce self sustained oscillations under controlled experimental conditions. Therefore different parameters, such as those related to elasticity, to acoustical coupling or to the subglottal pressure can be quantitatively studied. In this work we focused on the oscillation fundamental frequency and the upstream pressure in order to start (on-set threshold) either end (off-set threshold) oscillations in presence of a downstream acoustical resonator. As an example, it is shown how this data can be used in order to test the theoretical predictions of a simple one-mass model.
This paper develops a framework for TAG (Tree Adjoining Grammar) semantics that brings together ideas from different recent approaches.Then, within this framework, an analysis of scope is proposed that accounts for the different scopal properties of quantifiers, adverbs, raising verbs and attitude verbs. Finally, including situation variables in the semantics, different situation binding possibilities are derived for different types of quantificational elements.
Trubetzkoy's recognition of a delimitative function of phonology, serving to signal boundaries between morphological units, is expressed in terms of alignment constraints in Optimality Theory, where the relevant constraints require specific morphological boundaries to coincide with phonological structure (Trubetzkoy 1936, 1939, McCarthy & Prince 1993). The approach pursued in the present article is to investigate the distribution of phonological boundary signals to gain insight into the criteria underlying morphological analysis. The evidence from English and Swedish suggests that necessary and sufficient conditions for word-internal morphological analysis concern the recognizability of head constituents, which include the rightmost members of compounds and head affixes. The claim is that the stability of word-internal boundary effects in historical perspective cannot in general be sufficiently explained in terms of memorization and imitation of phonological word form. Rather, these effects indicate a morphological parsing mechanism based on the recognition of word-internal head constituents. Head affixes can be shown to contrast systematically with modifying affixes with respect to syntactic function, semantic content, and prosodic properties. That is, head affixes, which cannot be omitted, often lack inherent meaning and have relatively unmarked boundaries, which can be obscured entirely under specific phonological conditions. By contrast, modifying affixes, which can be omitted, consistently have inherent meaning and have stronger boundaries, which resist prosodic fusion in all phonological contexts. While these correlations are hardly specific to English and Swedish it remains to be investigated to which extent they hold cross-linguistically. The observation that some of the constituents identified on the basis of prosodic evidence lack inherent meaning raises the issue of compositionality. I will argue that certain systematic aspects of word meaning cannot be captured with reference to the syntagmatic level, but require reference to the paradigmatic level instead. The assumption is then that there are two dimensions of morphological analysis: syntagmatic analysis, which centers on the criteria for decomposing words in terms of labelled constituents, and paradigmatic analysis, which centers on the criteria for establishing relations among (whole) words in the mental lexicon. While meaning is intrinsically connected with paradigmatic analysis (e.g. base relations, oppositeness) it is not essential to syntagmatic analysis.
The contribution of von Kempelen’s “Mechanism of Speech” to the ‘phonetic sciences‘ will be analyzed with respect to his theoretical reasoning on speech and speech production on the one hand and on the other in connection with his practical insights during his struggle in constructing a speaking machine. Whereas in his theoretical considerations von Kempelen’s view is focussed on the natural functioning of the speech organs – cf. his membraneous glottis model – in constructing his speaking machine he clearly orientates himself towards the auditory result – cf. the bag pipe model for the sound generator used for the speaking machine instead. Concerning vowel production his theoretical description remains questionable, but his practical insight that vowels and speech sounds in general are only perceived correctly in connection with their surrounding sounds – i.e. the discovery of coarticulation – is clearly a milestone in the development of the phonetic sciences: He therefore dispenses with the Kratzenstein tubes, although they might have been based on more thorough acoustic modelling. Finally, von Kempelen’s model of speech production will be discussed in relation to the discussion of the acoustic nature of vowels afterwards [Willis and Wheatstone as well as von Helmholtz and Hermann in the 19th century and Stumpf, Chiba & Kajiyama as well as Fant and Ungeheuer in the 20th century].
