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.
The study offers a discourse-based account of the Spanish copula forms ser and estar, which are generally considered to be lexical exponents of the stage-level/individual-level contrast. It argues against the popular view that the distinction between SLPs and ILPs rests on a fundamental cognitive division of the world that is reflected in the grammar. As it happens, conceptual oppositions like “temporary vs. permanent” or “arbitrary vs. essential“ provide only a preference for the interpretation of estar and ser. In addition, the evidence for an SLP/ILP impact on the grammar turns out to be far less conclusive than is currently assumed. The study argues against event-based accounts of the ser/estar contrast in particular, showing that ser and estar pattern alike in failing all of the standard eventuality tests. The discourse-based account proposed instead assumes that ser and estar both display the same lexical semantics (which is identical to the semantics of English be, German sein, etc.); estar differs from ser only in presupposing a relation to a specific discourse situation. By using estar a speaker restricts his or her claim to a specific discourse situation, whereas by using ser, the speaker makes no such restriction. The preference for interpreting estar predications as denoting temporary properties and ser predications as denoting permanent properties follows from economy principles driving the pragmatic legitimation of estars discourse dependence. The analysis proposed in this paper can also account for the observation that ser predications do not give rise to thetic judgements. The proposal is couched in terms of the framework of DRT.
“Comments are very welcome!” This basic attitude and the many ways of implementing it contribute immensely to the fascination of engaging in scientific research. I am grateful to Theoretical Linguistics for providing a public platform for this kind of scholarly exchange and I thank all commentators for their thoughtful, stimulating, and often challenging contributions to my target article. My response will address two main issues that are raised by the commentaries. The first issue is shaped by a cluster of questions relating to ontology. The second issue concerns questions of methodology pertaining in particular to the problem of judging data.
Since Donald Davidson’s seminal work “The Logical Form of Action Sentences” (1967) event arguments have become an integral component of virtually every semantic theory. Over the past years Davidson´s proposal has been continuously extended such that nowadays event(uality) arguments are generally associated not only with action verbs but with predicates of all sorts. The reasons for such an extension are seldom explicitly justified. Most problematical in this respect is the case of stative expressions. By taking a closer look at copula sentences the present study assesses the legitimacy of stretching the Davidsonian notion of events and discusses its consequences. A careful application of some standard eventuality diagnostics (perception reports, combination with locative modifiers and manner adverbials) as well as some new diagnostics (behavior of certain degree adverbials) reveals that copular expressions do not behave as expected under a Davidsonian perspective: they fail all eventuality tests, regardless of whether they represent stage-level or individual-level predicates. In this respect, copular expressions pattern with stative verbs like know, hate, and resemble, which in turn differ sharply from state verbs like stand, sit, and sleep. The latter pass all of the eventuality tests and therefore qualify as true “Davidsonian state” expressions. On the basis of these empirical observations and taking up ideas of Kim (1969, 1976) and Asher (1993, 2000), an alternative account of copular expressions (and stative verbs) is provided, according to which the copula introduces a referential argument for a temporally bound property exemplification (= “Kimian state”). Considerations on some logical properties, viz. closure conditions and the latent infinite regress of eventualities, suggest that supplementing Davidsonian eventualities with Kimian states may yield not only a more adequate analysis of copula sentences but also a better understanding of eventualities in general.
In this paper I will discuss the formation of different types of yes/no questions in Serbian (examples in (1)), focusing on the syntactically and semantically puzzling example (1d), which involves the negative auxiliary inversion. Although there is a negative marker on the fronted auxiliary, the construction does not involve sentential negation. This coincides with the fact that the negative quantifying NPIs cannot be licensed. The question formation and sentential negation have similar syntactic effects cross-linguistically. This has led to various attempts to formulate a unifying syntactic account of the phenomena (ever since Klima 1964). One striking fact about the two syntactic contexts is that both license weak NPIs (Negative Polarity Items). It has been suggested (cf. Laka 1990, Culicover 1991) that the derivation of both interrogatives and negatives involves the same type of functional projection PolP (polarity phrase). One such account of the formation of negative interrogatives in Serbo- Croatian is offered by Progovac (2005). She proposes that there are two PolPs optionally cooccurring in the same clause, in which both positive and negative polarity items check their positive or negative features (following Haegeman and Zanuttini (1991) feature-checking account of negative structures, and the insights of Brown(1999) on the negation in Russian). On her account, the negative auxiliary question in (1d), is the case when both polarity phrases are present. The higher has [-pos +neg] features, and the lower one (below TP) is [-pos -neg]. Although her account correctly predicts the ungrammaticality of (2a) in contrast with (1c), it wrongly predicts the (2b) to be grammatical. I will argue that Progovac’s theory regarding the nature of the PolP is wrong. It employs both the binary feature valuation on the polarity head and the hierarchical ordering of the two polarity phrases, which eventually leads to overgeneration. On the account presented here the nature of the question marker (li vs zar) is highly relevant. Notice that (1b) and (1d) express presuppositions regarding the truth value of the propositions. In this way they contrast with (1a) and (1c). In addition, the type (1b) (with the question particle zar) can introduce both the positive and negative presupposition as shown in (3), which, semantically, makes this construction compatible with negative auxiliary questions in English (4a). The polarity items licensed in the relevant structures are also of the same type in both languages. The fronted-negative-auxiliary questions (1d) in Serbian are only possible with the particle li. In this case the presupposition is exclusively positive. The peculiar question/focus marking function of li (in Bulgarian and Russian) is well known. However, it is always assumed that its focus marking role is not relevant for the formation of yes/no questions. This I believe is not correct. The syntactic explanation of the interpretational facts points to the following: A) The possibility of the separate lexical encoding (particle zar) of the ‘rhetorical’ yes/no questions in Serbian allows the embedding of both positive and negated sentences, in which case the (weak) NPIs can remain in local relation with the negated verb. B) Recall that Serbian is an NC language, which requires local/c-command relation between the verbal negative marker and the NPI. With the negative inverted auxiliary questions this condition is not met, and the licensing of an n-word is not possible. C) The impossibility of licensing a weak NPI (i-words in the examples below) is due to the nature of the question marker li. (1) a. Da li je Vera videla ikoga / nekoga / *nikoga? DA Q aux Vera see.part.F.Sg anyone someone noone “Did Vera see anyone/someone/noone?” b. Zar je Vera videla ikoga / nekoga / *nikoga? ZAR aux Vera see.part.F.Sg anyone someone noone “Is it really the fact that Vera saw anyone/someone?” c. Je li Vera videla ikoga / nekoga /*nikoga? aux Q Vera see.part.F.Sg anyone someone noone “Did Vera see anyone/someone/noone?” d. Nije li Vera videla *ikoga / nekoga / *nikoga? neg+aux Q Vera see.part.F.Sg anyone someone noone “Didn’t Vera see someone?”/ “Vera saw someone, didn’t she?” (2) a. *Nije li Vera videla nikoga? neg+aux Q Vera see.part.F.Sg noone b. *Nije li Vera videla ikoga? neg+aux Q Vera see.part.F.Sg anyone (3) a. Zar je Vera videla nekoga / ikoga? ZAR aux Vera see.part.F.Sg someone/anyone b. Zar Vera nije videla nekoga/nikoga? ZAR Vera neg+aux see.part.F.Sg someone/anyone (4) a. Didn’t Vera (NOT) see someone/anyone? b. Vera saw someone, didn’t she?
In many languages, a passive-like meaning may be obtained through a noncanonical passive construction. The get passive (1b) in English, the se faire passive (2b) in French and the kriegen passive (3b) in German represent typical manifestations. This squib focuses on the behavior of the get-passive in English and discusses a number of restrictions associated with it as well as the status of get.
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.
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.
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.
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.

The epistemic step
(2005)
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.
Dictionaries contain lexicographic data whose occurrence is restricted to certain geo-graphical areas, subject fields, professions, etc. It is part of the duties of the lexicographer to give an account of such deviations to ensure a successful retrieval of the information on the part of the user. This contribution presents a discussion on labelling issues in the Dictionnaire Français–Mpongwé. Although the main focus is on the presentation of different types of labelling as well as problems in labelling, textual condensation procedures and mediostructural representations (to-gether with some aspects of the user perspective) are also critically evaluated. It is shown that these procedures reveal some inconsistencies which are not accounted for in the outer texts (front matter and back matter texts) of the dictionary. Finally suggestions are made for the improvement of the access structure of this dictionary.
A correct evaluation of the Slavic evidence for the reconstruction of the Indo- European proto-language requires an extensive knowledge of a considerable body of data. While the segmental features of the Slavic material are generally of corroborative value only, the prosodic evidence is crucial for the reconstruction of PIE. phonology. Due to the complicated nature of Slavic historical accentology, this has come to be realized quite recently.1 As a result, much of the earlier literature has become obsolete to the extent that it is based upon an interpretation which does not take the multifarious accentual developments into account. I shall give one example.
This paper addresses remarks made by Flemming (2003) to the effect that his analysis of the interaction between retroflexion and vowel backness is superior to that of Hamann (2003b). While Hamann maintained that retroflex articulations are always back, Flemming adduces phonological as well as phonetic evidence to prove that retroflex consonants can be non-back and even front (i.e. palatalised). The present paper, however, shows that the phonetic evidence fails under closer scrutiny. A closer consideration of the phonological evidence shows, by making a principled distinction between articulatory and perceptual drives, that a reanalysis of Flemming’s data in terms of unviolated retroflex backness is not only possible but also simpler with respect to the number of language-specific stipulations.
The present study shows that though retroflex segments can be considered articulatorily marked, there are perceptual reasons why languages introduce this class into their phoneme inventory. This observation is illustrated with the diachronic developments of retroflexes in Norwegian (North- Germanic), Nyawaygi (Australian) and Minto-Nenana (Athapaskan). The developments in these three languages are modelled in a perceptually oriented phonological theory, since traditional articulatorily-based features cannot deal with such processes.
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.
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).
War and death in business : some remarks on the nature of conceptualisation in the field economy
(2005)
The history of Slavic accentuation is complex. As a result, the significance of the Slavic accentual evidence is not immediately obvious to the average Indo-Europeanist. In this contribution I intend to render the material more easily accessible to the non-specialist. I shall focus on the Serbo-Croatian dialectal area, where the Proto-Slavic accentual system is better preserved than elsewhere. The main point of reference will be the neo-Štokavian system which was codified in the 19th century as a basis for the standard languages.
Holger Pedersen’s "Études lituaniennes" reflects the issues under discussion at the time of its publication (1933). Its five unequal chapters deal with the following topics: I. The Lithuanian future and its Indo-European origins: the sigmatic formation, the 3rd person zero ending, the short root vowels e and a, the shortening and metatony in the 3rd person, and the future participle. II. The accentuation of nouns in Lithuanian: accentual mobility in the Indo- European consonant stems and its absence in the o-stems, the origins of accentual mobility in Lithuanian nominal paradigms, the accentuation of separate case forms, and accentual peculiarities of the adjective. III. The acute tone of the root in consonant stems. IV. The past active participle. V. Secondary vocalic alternations: new vowel length and new acute tone.
The highly successful conference on Balto-Slavic accentology organized by Mate Kapovic and Ranko Matasovic has given much food for thought. It has clarified the extent of fundamental disagreements as well as established areas of common interest where the evidence seems to be ambiguous. In the following I shall comment upon some of the papers presented at the conference which are directly relevant to my own research.
Hittite ammuk 'me'
(2005)
In the Indo-European department of Leiden University, Alwin Kloekhorst has initiated a discussion on Hittite ammuk ‘me’. The central question is: where did the geminate come from? This has led me to reconsider the origin of the Indo-European personal pronouns against the background of my reconstruction of Indo-Uralic (2002: 221-225). For the historical data I may refer to Schmidt (1978).
Erdvilas Jakulis’ thorough, detailed and comprehensive study (2004) is an important contribution to our reconstruction of the Balto-Slavic verbal system. The following remarks are intended to complement his findings from a Slavic perspective. Jakulis demonstrates that the type of Lith. tekèti, teka ‘flow’ is largely of East Baltic provenance. He finds it difficult to identify the same type in Old Prussian.
It is gratifying to see that Jay Jasanoff has now (2004) adopted my theory that "the Balto-Slavic acute was a kind of stød or broken tone" (p. 172), which I have been advocating since 1973. Unfortunately, his acceptance of my view is not based on an evaluation of the comparative evidence (for which see Kortlandt 1985a) but on his desire to derive Balto-Slavic “acute” and "circumflex" syllables from the "bimoric" and "trimoric" long vowels which he assumes for Proto-Germanic as the reflexes of the Indo-European "acute" and "circumflex" tones of the neogrammarians. Since the original "circumflex" was limited to Indo-European VHV-sequences, Jasanoff proposes a whole series of additional lengthenings yielding "hyperlong" vowels in Germanic, Baltic and Slavic, which still do not suffice to eliminate the counter-evidence (cf. Kortlandt 2004b: 14). The reason for this failure is his unwillingness to recognize that lengthened grade vowels are circumflex in Balto-Slavic (cf. Kortlandt 1997a).
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].
It has been shown that visual cues play a crucial role in the perception of vowels and consonants. Conflicting consonantal stimuli presented in the visual and auditory modalities can even result in the emergence of a third perceptual unit (McGurk effect). From a developmental point of view, several studies report that newborns can associate the image of a face uttering a given vowel to the auditory signal corresponding to this vowel; visual cues are thus used by the newborns. Despite the large number of studies carried out with adult speakers and newborns, very little work has been conducted with preschool-aged children. This contribution is aimed at describing the use of auditory and visual cues by 4 and 5-year-old French Canadian speakers, compared to adult speakers, in the identification of voiced consonants. Audiovisual recordings of a French Canadian speaker uttering the sequences [aba], [ada], [aga], [ava], [ibi], [idi], [igi], [ivi] have been carried out. The acoustic and visual signals have been extracted and analysed so that conflicting and non-conflicting stimuli, between the two modalities, were obtained. The resulting stimuli were presented as a perceptual test to eight 4 and 5-year-old French Canadian speakers and ten adults in three conditions: visual-only, auditory-only, and audiovisual. Results show that, even though the visual cues have a significant effect on the identification of the stimuli for adults and children, children are less sensitive to visual cues in the audiovisual condition. Such results shed light on the role of multimodal perception in the emergence and the refinement of the phonological system in children.
In this paper the issue of the nature of the representations of the speech production task in the speaker's brain is addressed in a production-perception interaction framework. Since speech is produced to be perceived, it is hypothesized that its production is associated for the speaker with the generation of specific physical characteristics that are for the listeners the objects of speech perception. Hence, in the first part of the paper, four reference theories of speech perception are presented, in order to guide and to constrain the search for possible correlates of the speech production task in the physical space: the Acoustic Invariance Theory, the Adaptive Variability Theory, the Motor Theory and the Direct-Realist Theory. Possible interpretations of these theories in terms of representations of the speech production task are proposed and analyzed. In a second part, a few selected experimental studies are presented, which shed some light on this issue. In the conclusion, on the basis of the joint analysis of theoretical and experimental aspects presented in the paper, it is proposed that representations of the speech production task are multimodal, and that a hierarchy exists among the different modalities, the acoustic modality having the highest level of priority. It is also suggested that these representations are not associated with invariant characteristics, but with regions of the acoustic, orosensory and motor control spaces.
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.
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 work investigates laryngeal and supralaryngeal correlates of the voicing contrast in alveolar obstruent production in German. It further studies laryngealoral co-ordination observed for such productions. Three different positions of the obstruents are taken into account: the stressed, syllable initial position, the post-stressed intervocalic position, and the post-stressed word final position. For the latter the phonological rule of final devoicing applies in German. The different positions are chosen in order to study the following hypotheses:
1. The presence/absence of glottal opening is not a consistent correlate of the voicing contrast in German.
2. Supralaryngeal correlates are also involved in the contrast.
3. Supralaryngeal correlates can compensate for the lack of distinction in laryngeal adjustment.
Including the word final position is motivated by the question whether neutralization in word final position would be complete or whether some articulatory residue of the contrast can be found.
Two experiments are carried out. The first experiment investigates glottal abduction in co-ordination with tongue-palate contact patterns by means of simultaneous recordings of transillumination, fiberoptic films and Electropalatography (EPG). The second experiment focuses on supralaryngeal correlates of alveolar stops studied by means of Electromagnetic Articulography (EMA) simultaneously with EPG. Three German native speakers participated in both recordings. Results of this study provide evidence that the first hypothesis holds true for alveolar stops when different positions are taken into account. In fricative production it is also confirmed since voiceless and voiced fricatives are most of the time realised with glottal abduction. Additionally, supralaryngeal correlates are involved in the voicing contrast under two perspectives. First, laryngeal and supralaryngeal movements are well synchronised in voiceless obstruent production, particularly in the stressed position. Second, supralaryngeal correlates occur especially in the post-stressed intervocalic position. Results are discussed with respect to the phonetics-phonology interface, to the role of timing and its possible control, to the interarticulatory co-ordination, and to stress as 'localised hyperarticulation'.
Studying kinematic behavior in speech production is an indispensable and fruitful methodology in order to describe for instance phonemic contrasts, allophonic variations, prosodic effects in articulatory movements. More intriguingly, it is also interpreted with respect to its underlying control mechanisms. Several interpretations have been borrowed from motor control studies of arm, eye, and limb movements. They do either explain kinematics with respect to a fine tuned control by the Central Nervous System (CNS) or they take into account a combination of influences arising from motor control strategies at the CNS level and from the complex physical properties of the peripheral speech apparatus. We assume that the latter is more realistic and ecological. The aims of this article are: first, to show, via a literature review related to the so called '1/3 power law' in human arm motor control, that this debate is of first importance in human motor control research in general. Second, to study a number of speech specific examples offering a fruitful framework to address this issue. However, it is also suggested that speech motor control differs from general motor control principles in the sense that it uses specific physical properties such as vocal tract limitations, aerodynamics and biomechanics in order to produce the relevant sounds. Third, experimental and modelling results are described supporting the idea that the three properties are crucial in shaping speech kinematics for selected speech phenomena. Hence, caution should be taken when interpreting kinematic results based on experimental data alone.
