O ensino/aprendizagem da metafonia do português como língua estrangeira por aprendizes alemães
(2009)
The present article deals with a phenomenon of the portuguese language which is well-known and yet rather neglected in brazilian schools as well as in schools abroad: metaphony. Since this regular vowel change is a phenomenon that foms part exclusively of speech and is not represented in writing, it constitutes a problem for foreign learners, in our case speakers of German. We therefore propose a strategy by the help of which the phenomenon of metaphony in Portuguese can be explained, based on analogies with a similar regular sound change in the German language, called Umlaut. Our study is based upon data collected among students at Christian-Albrechts-Universität in Northern Germany.
Many teachers of German as a second language make some statements regarding this language that mix concepts from three distinct fields: Orthography (letters), Phonetics (phones or speech sounds) and Phonology (phonemes). In this paper I attempt to shed some light on these concepts and fields. I also provide examples of such statements and make comments on them.
Eines der Hauptmerkmale, welches das Ionisch-Attische von den übrigen altgriechischen Dialekten unterscheidet, ist die Vertretung des idg. * ā durch ē. Idg. *ā kommt in den übrigen Dialekten als ā vor. So entspricht zum Beispiel dem idg. *māter (lat. māter, ai. mātā) äol.-dor. mā́tēr, aber mḗtēr im ion.-att. […] Selbstverständlich ist die Zurückführung auf idg. Formen mit ā ein Ergebnis, zu dem man erst durch die Rekonstruktionsmethoden der Vergleichenden Sprachwissenschaft kommt. In dem Bereich des ion.-att. Dialekts wird jedoch weiter unterschieden, da bei bestimmten lautlichen Umgebungen (nach den Lauten i, e und r) im Att. – wie auch im Äol., Dor. – ā und kein ē vorkommt, wie man erwarten würde und wie es wirklich der Fall im Ion. ist. […]
1.2. Wegen dieser unterschiedlichen phonologischen Situation, die man im Att. […] findet, stellen sich in Bezug auf das phonologische System des Altgriechischen (des ion.-att. Dialekts) die folgenden wesentlichen Fragen: (A) Wie soll man im Att. die Anwesenheit von ā statt des erwarteten ē erklären? (B) (I) Wurde das urgr. ā direkt zu ē (ē̡) im Ion.-att. oder hat es eine Zwischenstufe gegeben in dem Sinne, daß es zunächst zu ǟ (vorderer, palataler Laut) wurde und später zu ē̡, obwohl es in der Schrift immer durch H (MHTEP) im Att. repräsentiert wurde?
(II) Wenn es wirklich eine Zwischenstufe mit ǟ gegeben hat, hat sie so lange gedauert, daß ǟ als ein selbständiges Phonem des phonologischen Systems der langen Vokale des Ion.-att. und besonders des Att. betrachtet werden kann?
Der zweite Teil der Frage (B) wird direkt mit dem Problem der Chronologie der Verschmelzung ("merger") von ǟ und ā̡ verknüpft. (Da die Gründe, die für den phonematischen Wert des ǟ sprechen, stark genug sind, wie durch die folgende Analyse gezeigt werden wird, wird ǟ hier im voraus als Phonem betrachtet, und das soll hier auch als Arbeitshypothese dienen.)
Der vorliegende Arbeitsbericht ist die Zusammenfassung eines Beitrags zu einem von Prof, Dr. H. Seiler geleitetem "Field-work-Seminar" mit Japanisch als exemplarischer Objektsprache. In diesem Seminar wurden praktische Verfahren und Methoden erörtert, die der Linguist im field work benutzen muß, um seine Arbeit, Data zu kollationieren und diese gleichzeitig auch schon einer Voranalyse zu unterziehen, rationell und deskriptiv adäquat durchzuführen. […] Die Ausdrücke "phonetisch", "phonemisch", ':morphophonemisch" etc. sind im folgenden lediglich als prätheoretische Begriffe aufzufassen. Die Übergänge von einer "phonetischen" zu einer "phonemischen" und von dieser zu einer "morphophonemlschen" Notierung usw. sind hier verstanden als nach gewissen Plausibilitätskriterien durchgeführte Abstrahierungen, die ein sinnvolles Aufstellen und Behandeln des Corpus ermöglichen sollen. Damit ist die Frage der, Struktur und des Status eines "morphophonemischen Teils" im Rahmen eines spezifischen Grammatikmodells weder gestellt noch beantwortet.
Phonetische Substanz und phonologische Theorie : eine Fallstudie zum Erstspracherwerb des Deutschen
(1991)
Diese Arbeit stellt einen Versuch dar. phonologische Theorien auf ihre Anwendbarkeit im Bereich des Erstspracherwerbs hin zu untersuchen. Ziel ist dabei letztlich. "substantielle Erklärungen" (Ohaia & Kawasaki 1964: 113f) phonologischer Phänomene zu finden. d.h. Erklärungen. die sich möglichst auf externe Evidenz stützen und weitergehende Vorhersagen und Generalisierungen zulassen. […] Schon bei der Untersuchung zweier oder mehrerer Kinder stellt sich heraus. daß diese eine Vielzahl von unterschiedlichen Strategien zur Vereinfachung oder auch Vermeidung komplexer Strukturen verwenden (Intersubjektive Variation, vgl. Ingram 1989: 212f. und Kleinhenz & Weyerts 1990). Zum Teil sind solche Unterschiede wohl auf individuelle Fähigkeiten. zum Teil vermutlich auch auf den sprachlichen Input zurückzuführen. also z.B. die Häufigkeit und die Deutlichkeit der Aussprache bestimmter Wörter und Segmente in der lnputsprache. Von besonderer Bedeutung ist es schließlich, die Stadien des Erwerbs unterschiedlicher Sprachen zu vergleichen. da sich so am ehesten feststellen läßt. Ob der Faktor der Input-Sprache entscheidendes Gewicht hat oder ob es deutliche sprachübergreifende Gesetzmäßigkeiten gibt. […] Die[] unterschiedlichen Aspekte lassen sich innerhalb einer Theorie der "Selbstorganisation" (oder "Emergenz") sprachlicher Strukturen durchaus vereinbaren. Dieser Ansatz bildet daher den Hintergrund der hier vorgenommenen Beschreibung.
Gegenstand dieser Arbeit sind die englischen Lehnwörter des Samoanischen, einer westpolynesischen Sprache. Als Basis der Untersuchung und Quelle des bearbeiteten Lehnwortschatzes dient das "Lexicon of foreign loan-words in the Samoan language" von Cain (1986)1. Hierbei handelt es sich um eine Auflistung der lexikalischen Entlehnungen im Samoanischen mit kurzen enzyklopädischen Erläuterungen. Ziel der vorliegenden Arbeit soll sein, die Integration der englischen Lehnwörter in die samoanische Sprache darzustellen und gegebenenfalls Regularitäten bezüglich der Assimilation an das samoanische Phoneminventar aufzuzeigen.
U članku se opisuje morfonologija glagolske osnove u prezentskoj paradigmi na građi hrvatsko-crkvenoslavenskih (dalje: HCS) glagola s temeljnom osnovom na -i- u kojih tom završnom -i- prethodi zubni sonant: r, l, n (tj. tipa tvori-ti, moli-ti, brani-ti). U obzir su uzeti svi glagolski leksemi tog tipa iz kartoteke Rječnika crkvenoslavenskoga jezika hrvatske redakcije: 110 li-glagola, 127 ni-glagola i 83 ri-glagola i njihovi prezentski oblici. Metoda opisa je usporedba dotičnog fragmenta HCS gramatike sa staroslavenskim stanjem kao i sa stanjem u starohrvatskim (čakavskim) govorima. U staroslavenskom jeziku u prezentskoj je paradigmi tihglagola osnova okrnjena (tj. okrnjen je sufiks -i-) i pojavljuje se u dvije varijante: palatalnoj (u 1. licu jednine), i tvrdoj (u svim ostalim oblicima). Tako u prezentu nalazimo u osnovi alternacije r ~ ŕ, l ~ ĺ i n ~ ń. U HCS tekstovima morfonološki su najinovativniji ri-glagoli. Kako je u hrvatskom depalataliziran fonem ŕ, kod ri-glagola nije sačuvan staroslavenski morfonološki model. HCS građa ne pokazuje staroslavensku alternaciju r ~ ŕ, tj. kod ri-glagola nema variranja osnove u prezentu (okrnjena osnova u svim oblicima završava nepalatalnim suglasnikom). Kod li-glagola i ni-glagola staroslavenski je morfonološki model očuvan. Međutim, u tekstovima su ipak potvrđene rijetke devijacije od tog modela. Naime, usprkos postojanju grafijskoga sredstva za označavanje palatalnosti fonema ĺ i ń ispred gramatičkog morfema 1. lica jednine -u (tj. uporaba slova ű iza l, n), neki su pisari u rijetkim slučajevima izostavljali označavanje palatalnosti, tj. pisali grafem u (molu, branu). Autorica predlaže različita moguća objašnjenja te pogreške i utvrđuje u kojoj je mjeri ta pojava ograničena na određene HCS tekstove.

Das Wogeo ist eine austronesische Sprache, die von etwa 1500 Menschen auf den Inseln Vokeo […] und Koil […] gesprochen wird. Da es sich beim Wogeo um eine bislang größtenteils unbeschriebene Sprache handelt, sind zum Verständnis der Ausführungen im Hauptteil dieser Arbeit sowie zur allgemeinen Orientierung einige einleitende Erklärungen nötig. Diese sind von unterschiedlicher Art: Zunächst wird die natürliche Umgebung der beiden Inseln, auf denen die Sprache gesprochen wird, kurz dargestellt. Dann werden die für das Verständnis der soziolinguistischen Lage der Sprache relevanten Aspekte beleuchtet. Zur Orientierung folgt ein kurzer Abriß der Position des Wogeo innerhalb der austronesischen Sprachfamilie. Schließlich leitet eine Darstellung des bisherigen Forschungsstandes über das Wogeo zum Hauptteil der Arbeit über.
Die vorliegende Arbeit soll sich mit dem „Zusammenziehen von Wörtern“ beschäftigen, das als typisch für die „Pottsprache“ […] angesehen wird. Dieses Zusammenziehen soll innerhalb der Klitisierungsforschung anhand zweier Fälle untersucht werden. Zum einen sollen reduzierte Formen der Pronomina und zum anderen reduzierte Artikelformen, nämlich die des bestimmten und des unbestimmten Artikels, als Untersuchungsgegenstand dienen. Dieses soll auf einer empirischen Basis, dass heißt auf der Basis von erhobenen und analysierten Sprachdaten, geschehen. Der erste Schritt soll dabei eine Darstellung der hier behandelten Sprachvarietät sein. […] Der zweite Schritt besteht in einer Darstellung der Theorie der Klitisierung […] Nachdem der Hintergrund dieser Arbeit dargestellt worden ist, folgt die eigentliche Analyse. Zunächst wird die Klitisierung von Pronomina untersucht […], dann die von Artikelformen […]. Beide Phänomene werden nacheinander auf ihre Eigenschaften hin untersucht, um dann zum Schluss zu einer Hypothese aus der bisherigen Forschung, nämlich die der flektierten Präpositionen, Stellung zu beziehen […]. Abschließend soll versucht werden die Ergebnisse dieser Arbeit in den Forschungsstand bei der Erforschung von Klitisierung auf der einen Seite und der Varietät Ruhrdeutsch auf der anderen Seite einzuordnen […].
There is every reason to welcome the revised edition (2009) of Thomas Olander’s dissertation (2006), which I have criticized elsewhere (2006). The book is very well written and the author has a broad command of the scholarly literature. I have not found any mistakes in Olander’s rendering of other people’s views. This makes the book especially useful as an introduction to the subject. It must be hoped that the easy access to a complex set of problems which this book offers will have a stimulating effect on the study of Balto-Slavic accentology.
All's well that ends well
(2009)
A few years ago, Jasanoff adopted the central tenet of my accentological theory, viz. that the Balto-Slavic acute was a stød or glottal stop, not a rising tone (cf. Kortlandt 1975, 1977, 2004, Jasanoff 2004a). Of course, nobody will believe Jasanoff’s claim that he arrived at the same result independently thirty years after I published it and ten years after we discussed it when he came to Leiden to visit us. Though at the time he haughtily dismissed “the tangle of secondary hypotheses and “laws” that clutter the ground in the field of Balto-Slavic accentology” (Jasanoff 2004b: 171), he has now recognized the importance of Pedersen’s law, Hirt’s law, Winter’s law, Meillet’s law, Dolobko’s law, Dybo’s law and Stang’s law and largely accepted my relative chronology of these accent laws, including the loss of the acute shortly before Stang’s law (cf. Jasanoff 2008). He has also accepted my split of Pedersen’s law into a Balto-Slavic and a Slavic phase (to which a Lithuanian phase must be added), my thesis that the tonal contours of Baltic and Slavic languages are post-Balto-Slavic innovations (cf. Jasanoff 2008: 344, fn. 10), and the rise of a tonal distinction on non-acute initial syllables before Dybo’s law which I discussed at some length in my review (1978) of Garde’s monograph (1976). This is great progress.
West Slavic accentuation
(2009)
At the time of the earliest reconstructible dialectal divergences, which belong to the Late Middle Slavic period of my chronology (stages 7.0 - 8.0 of Kortlandt 1989a, 2003, 2008), the West Slavic languages represented the most conservative part of the Slavic dialects (cf. Kortlandt 1982b: 191 and 2003: 231).
It appears that the complexity of Slavic historical accentology is prohibitive for most non-specialists in the field. It may therefore be useful to approach the subject from a number of different angles in order to render it more accessible to a wider audience. In the following I shall discuss the separate accent paradigms and their development from the Late Balto-Slavic system, which is structurally similar to that of modern Lithuanian, up to the end of the Proto-Slavic period, when the system resembled what we find in modern Serbo-Croatian. The numbering of the stages 1.0 through 10.12 is the same as in my earlier publications (1989, 2003, 2005, 2006a, 2008b). For the rise and development of the accentual system up to the end of the Balto-Slavic period I may refer to my discussion (2006b, 2008a) of Olander’s dissertation (2006). It resulted in a system of four major and two minor accent types.
After the very well-organized Leiden conference for which we must be grateful to Tijmen Pronk, it seems appropriate for me to review some of the papers, as I did after the previous conferences in Zagreb and Copenhagen. The aim of this review is merely to point out some of the differences of opinion which require further debate.
Like its predecessor in Zagreb, the conference on Balto-Slavic accentology in Copenhagen was a great success. The enthusiasm of the organizers Adam Hyllested and Thomas Olander proved highly effective in stimulating discussion among the participants. While in Zagreb most papers dealt with Slavic data, in Copenhagen the emphasis was on Balto-Slavic problems.
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).
Koivulehto and Vennemann have recently (1996) revived Posti’s theory (1953) which attributed Finnic consonant gradation to Germanic influence, in particular to the influence of Verner’s law. This theory disregards the major differences between Finnic and Saami gradation (cf. Sammallahti 1998: 3) and ignores the similar gradation in Nganasan and Selkup (cf. Kallio 2000: 92).
The Indo-Uralic verb
(2002)
C.C. Uhlenbeck made a distinction between two components of Proto-Indo-European, which he called A and B (1935a: 133ff.). The first component comprises pronouns, verbal roots, and derivational suffixes, and may be compared with Uralic, whereas the second component contains isolated words, such as numerals and most underived nouns, which have a different source. The wide attestation of the Indo-European numerals must be attributed to the development of trade resulting from the increased mobility which was the primary cause of the Indo-European expansions. Numerals do not belong to the basic vocabulary of a neolithic culture, as is clear from their absence in Proto-Uralic (cf. also Collinder 1965: 112) and from the spread of Chinese numerals throughout East Asia. Though Uhlenbeck objects to the term “substratum” for his B complex, I think that it is a perfectly appropriate denomination.
Most scholars nowadays reconstruct a static root present with an alternation between lengthened grade in the active singular and full grade in the active plural and in the middle. I am unhappy about this traditional methodology of loosely postulating long vowels for the proto-language. What we need is a powerful theory which explains why clear instances of original lengthened grade are so very few and restrains our reconstructions accordingly. Such a theory has been available for over a hundred years now: it was put forward by Wackernagel in his Old Indic grammar (1896: 66-68). The crucial element of his theory which is relevant in the present context is that he assumed lengthening in monosyllabic word forms, such as the 2nd and 3rd sg. active forms of the sigmatic aorist injunctive.
S.R. Ramsey writes (1979: 162): "The patterning of tone marks in Old Kyoto texts divides the vocabulary into virtually the same classes as those arrived at by comparing the accent distinctions found in the modern dialects. This means that the Old Kyoto dialect had a pitch system similar to that of proto-Japanese. The standard language of the Heian period may not actually be the ancestor of all the dialects of Japan, but at least as far as the accent system is concerned, it is close enough to the proto system to be used as a working model. The significance of this fact is important: It means that each of the dialects included in the comparison has as much to tell, at least potentially, as any other dialect about Old Kyoto accent."
A correct interpretation of the genitive plural forms in Slavic and related languages requires a detailed chronological analysis of the material. At every stage of development we have to reckon with both phonetically regular and analogical forms. Analogy operates quite often along the same lines in different periods. Explaining an analogic change amounts to indicating a model, a motivation, and a stage of development for its effectuation. If one of these cannot be indicated, we must look for a phonetic explanation.
Die sprachlichen Beispiele [...] sind dem Korpus „Institutionelle Konfliktgespräche“ des Instituts für deutsche Sprache in Mannheim entnommen. Es sind vorgerichtliche Schlichtungen in Nachbarschaftsstreitigkeiten aus dem kurpfälzischen Raum. Die Gespräche liegen dort in einer Transkription vor, die nicht nur deshalb unzureichend ist, weil Nonstandardmuster weitgehend in Standard wiedergegeben werden. Wir haben zwei der Gespräche völlig neu transkribiert. Beide Gespräche werden von demselben Schlichter geführt. Sie sind je etwa 45 Minuten lang, im ersten Gespräch, gekennzeichnet als „Die Mopeds“, verwendet der Schlichter nach IPA-Transkription ca. 12.000 Laute, im zweiten, gekennzeichnet als „Alte Sau“, ca. 14.000. Im folgenden werden die ersten 2.000 Laut aus den Äußerungen des Schlichters analysiert. Zum Vergleich haben wir einen in einer traditionellen Dialekterhebung aufgenommenen, überwiegend monologischen Text analysiert: einen ebenfalls 2000 Laute umfassenden Ausschnitt aus der Aufname einer jungen Mutterstadter Sprecherin aus den 50er Jahren, ediert von Karch. Die Frage der Standarddefinition, des Vergleichsmaßstabes und der Wahl der Einheiten soll hier nicht diskutiert werden: Wir gehen aus von Lauten, wie sie sich mit den Zeichen des IPA darstellen lassen. Als Kodifikation des Standards wurde, um einen vorläufig praktikablen Maßstab zu haben, das Duden-Aussprachewörterbuch zu Grunde gelegt. Dort für ein Morphem nicht verzeichnete Laute wurden Unberücksichtigt blieb die Unterscheidung zwischen stimmhaften und nicht stimmhaften Konsonanten. Stotternde, verzögernde, lachende [..] etc. wurden bisher weder ausgeblendet, noch zu Nonstandard gerechnet. Einer vorgängigen Skalierung und Gewichtung sprachlicher Merkmale bedarf es nicht. Es genügt eine erste Dichotomisierung und alle weiteren Differenzierungen können im Anschluss daran durchgespielt werden.
Eine Einführung in eine Reihe von linguistischen Phänomenen von Phonetik bis Pragmatik, einige theoretische Ansätze zur Beschreibung/für diese Phänomene, mit einem Blick auf Phänomene und Ansätze, die für kognitive Linguisten und Neurologen interessant sind. Der Begriff "Schnittstelle" ist in der Linguistik ein technischer Terminus, der beschreibt, wie verschiedene Typen von Phänomenen miteinander in einer Beziehung stehen, aber der Terminus soll auch beschreiben, wie linguistische und außerlinguistische Phänomene ineinandergreifen.
In this paper we provide an account of the historical development of Polish and Russian sibilants. The arguments provided here are of theoretical interest because they show that (i) certain allophonic rules are driven by the need to keep contrasts perceptually distinct, (ii) (unconditioned) sound changes result from needs of perceptual distinctiveness, and (iii) perceptual distinctiveness can be extended to a dass of consonants, i.e. the sibilants. The analysis is cast within Dispersion Theory by providing phonetic and typological data supporting the perceptual distinctiveness claims we make.
In this article I reanalyze sibilant inventories of Slavic languages by taking into consideration acoustic, perceptive and phonological evidence. The main goal of this study is to show that perception is an important factor which determines the shape of sibilant inventories. The improvement of perceptual contrast essentially contributes to creating new sibilant inventories by (i) changing the place of articulation of the existing phonemes (ii) merging sibilants that are perceptually very close or (iii) deleting them. It has also been shown that the symbol š traditionally used in Slavic linguistics corresponds to two sounds in the IPA systemsystem: it stands for a postalveolar sibilant (ʃ) in some Slavic languages, as e.g. Bulgarian, Czech, Slovak, some Serbian and Croatian dialects, whereas in others like Polish, Russian, Lower Sorbian it functions as a retroflex (s). This discrepancy is motivated by the fact that ʃ is not optimal in terms of maintaining sufficient perceptual contrast to other sibilants such as s and ç. If ʃ occurs together with s and sj there is a considerable perceptual distance between them but if it occurs with ç in an inventory, the distance is much smaller. Therefore, the strategy most languages follow is the change from a postalveolar to a retroflex sibilant.
In this paper it is argued 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.
This paper evaluates trills [r] and their palatalized counterparts [rj] from the point of view of markedness. It is argued that [r]s are unmarked sounds in comparison to [rj]s which follows from the examination of the following parameters: (a) frequency of occurrence, (b) articulatory and aerodynamic characteristics, (c) perceptual features, (d) emergence in the process of language acquisition, (e) stability from a diachronic point of view, (f) phonotactic distribution, and (g) implications. Several markedness aspects of [r]s and [rj] are analyzed on the basis of Slavic languages which offer excellent material for the evaluation of trills. Their phonetic characteristics incorporated into phonetically grounded constraints are employed for a phonological OT-analysis of r-palatalization in two selected languages: Polish and Czech.
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.
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].
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).
The study investigates the contribution of tactile and auditory feedback in the adaptation of /s/ towards a palatal prosthesis. Five speakers were recorded via electromagnetic articulography, at first without the prosthesis, then with the prosthesis and auditory feedback masked, and finally with the prosthesis and auditory feedback available. Tongue position, jaw position and acoustic centre of gravity of productions of the sound were measured. The results show that the initial adaptation attempts without auditory feedback are dependent on the prosthesis type and directed towards reaching the original tongue palate contact pattern. Speakers with a prosthesis which retracted the alveolar ridge retracted the tongue. Speakers with a prosthesis which did not change the place of the alveolar ridge did not retract the tongue. All speakers lowered the jaw. In a second adaptation step with auditory feedback available speakers reorganised tongue and jaw movements in order to produce more subtle acoustic characteristics of the sound such as the high amplitude noise which is typical for sibilants.
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.
As has been noted previously, speakers with coronally low "flat" palates exhibit less articulatory variability than speakers with coronally high "domeshaped" palates. This phenomenon is investigated by means of a tongue model and an EPG experiment. The results show that acoustic variability depends on the shape of the vocal tract. The same articulatory variability leads to more acoustic variability if the palate is flat than if it is domeshaped. Furthermore, speakers with domeshaped palates show more articulatory variability than speakers with flat palates. The results are explained by different control strategies by the speakers. Speakers with flat palates reduce their articulatory variability in order to keep their acoustic variability low.
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.
