In this paper, we report on an experiment showing how the introduction of prosodic information from detailed syntactic structures into synthetic speech leads to better disambiguation of structurally ambiguous sentences. Using modifier attachment (MA) ambiguities and subject/object fronting (OF) in German as test cases, we show that prosody which is automatically generated from deep syntactic information provided by an HPSG generator can lead to considerable disambiguation effects, and can even override a strong semantics-driven bias. The architecture used in the experiment, consisting of the LKB generator running a large-scale grammar for German, a syntax-prosody interface module, and the speech synthesis system MARY is shown to be a valuable platform for testing hypotheses in intonation studies.
This paper reconciles the standpoint that language users do not aim at improving their sound systems with the observation that languages seem to improve their sound systems. Computer simulations of inventories of sibilants show that Optimality-Theoretic learners who optimize their perception grammars automatically introduce a so-called prototype effect, i.e. the phenomenon that the learner’s preferred auditory realization of a certain phonological category is more peripheral than the average auditory realization of this category in her language environment. In production, however, this prototype effect is counteracted by an articulatory effect that limits the auditory form to something that is not too difficult to pronounce. If the prototype effect and the articulatory effect are of a different size, the learner must end up with an auditorily different sound system from that of her language environment. The computer simulations show that, independently of the initial auditory sound system, a stable equilibrium is reached within a small number of generations. In this stable state, the dispersion of the sibilants of the language strikes an optimal balance between articulatory ease and auditory contrast. The important point is that this is derived within a model without any goal-oriented elements such as dispersion constraints.
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.
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).
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.
Evaluating phonological status : significance of paradigm uniformity vs. prosodic group effects
(2007)
A central concern of linguistic phonetics is to define criteria for determining the phonological status of sounds or sound properties observed in phonetic surface form. Based on acoustic measurements we show that the occurrence of syllabic sonorants vs. schwa-sonorant sequences in German is determined exclusively by segmental and prosodic structure, with no paradigm uniformity effects. We argue that these findings are consistent with a uniform representation of syllabic sonorants as schwa sonorant sequences in the lexicon. The stability of schwa in CVC-suffixes (e.g. the German diminutive suffix -chen), as opposed to its phonetic absence in a segmentally comparable underived context, is argued to be conditioned by the prosodic organisation of such suffixes external to the phonological word of the stem.
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.
In Ocotepec Mixe, the stem-initial sibilants /s tÉs ß/ undergo a palatalization process when the prefix /j/ is added. Descriptions of other Mixe languages report that this palatalization is realized either as addition of a glide (in the case of the alveolar and retroflex sibilants) or as a change in the primary place of articulation (in the case of the affricate). The acoustic measurements in the present study indicate that all palatalized sibilants in Ocotepec have an additional glide, unless they are followed by the high front vowel(s) /i (e)/, and that both the affricate and retroflex fricative show a consistent change in primary place of articulation under palatalization.
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.
