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 [r ]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.
The present study, based on a typological survey of ca. 70 languages, offers a systematization of consonantal insertions by classifying them into three main types: grammatical, phonetic, and prosodic insertions. The three epenthesis types essentially differ from each other in terms of preferred sounds, domains of application, the role of segmental context, their occurrence cross-linguistically, the extent of variation and phonetic explication.
The present investigation is significantly different from other analyses of consonantal epentheses in the sense that it neither invokes markedness nor diachronic state of the processes under discussion. Instead, it considers the different nature of the epenthetic segments by referring to the representational levels and/or domains which are relevant for their appearance.
(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.
In this artiele 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 s traditionally used in Slavic linguistics corresponds to two sounds in the IP A system: it stands for a postalveolar sibilant (ʃ) in some Slavic languages, as e.g. Bulagarian, Czech, Slovak, some Serbian and Croatian dialects, whereas in others like Polish, Russian, Lower Sorbian it functions as a retroflex (ʂ). 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 ɕ. If ʃ occurs together with s (and sʲ) there is a considerable perceptual distance between them but if it occurs with ɕ in an inventory, the distance is much smaller. Therefore, the strategy most languages follow is the change from a postalveolar to a retroflex sibilant.
This paper investigates how syntax and focus interact in deriving the phonological phrasing of utterances in Xhosa, a Bantu language spoken in South Africa. Although the influence of syntax on phrasing is uncontroversial, a purely syntactic analysis cannot account for all the data reported for Xhosa by Jokweni (1995). Focus influences the phrasing in that it inserts a phonological phrase-boundary after the focused constituent. This generalization can account for the variation found in the phrasing of adverbials.
The findings are dealt with in an OT-based framework following Truckenbrodt's work on Chichewa (1995, 1999) which is extended to the phrasing of adjuncts.
The morpho-syntax of relative clauses in Sotho-Tswana is relatively well-described in the literature. Prosodic characteristics, such as tone, have received far less attention in the existing descriptions. After reviewing the basic morpho-syntactic and semantic features of relative clauses in Tswana, the current paper sets out to present and discuss prosodic aspects. These comprise tone specifications of relative clause markers such as the demonstrative pronoun that acts as the relative pronoun, relative agreement concords and the relative suffix. Further prosodic aspects dealt with in the current article are tone alternations at the juncture of relative pronoun and head noun, and finally the tone patterns of the finite verbs in the relative clause. The article aims at providing the descriptive basis from which to arrive at generalizations concerning the prosodic phrasing of relative clauses in Tswana.
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.
In this work, I examine a set of languages which appear to require resyllabification postlexically; in less derivational terms, a word's syllabification in isolation differs from its syllabification in a phrase-internal context. Although many people, myself included, have been looking at such cases in isolation over the years, I bring together several examples here to see what features they share and how an Optimality Theory analysis improves upon rule-based derivational approaches.
This study examines articulatory and acoustic inter-speaker variability in the production of the German vowels /i/, /u/ and /a/. Our subjects are 3 monozygotic twin pairs (2 female and 1 male pair) and 2 dizygotic female twin pairs. All of them were born, raised and are still living in Berlin and see their twin brother or sister regularly. We assume that monozygotic twins that are genetically identical and share the same physiology should be more similar in their articulation than dizygotic twins but that the shared time and social environment of twins, regardless of their genetic similarity, also plays a crucial role in the acoustic similarity of twins. Articulatory measurements were made with EMA (Electromagnetic Articulography) and the target positions of the produced vowels were analyzed. Additionally, the formants F1-F4 of each vowel were measured and compared within the twin pairs. Our data seems to point out the importance of a shared environment and the strong influence of learning over the anatomical identity of the monozygotic twins regarding the production of vowels. But, additional results suggest (1) the impact of physiology on the production of a vowel following a velar consonant and (2) the interaction of physiology and stress in inter-speaker variability.
In the research field initiated by Lindblom & Liljencrants in 1972, we illustrate the possibility of giving substance to phonology, predicting the structure of phonological systems with nonphonological principles, be they listener-oriented (perceptual contrast and stability) or speaker-oriented (articulatory contrast and economy). We proposed for vowel systems the Dispersion-Focalisation Theory (Schwartz et al., 1997b). With the DFT, we can predict vowel systems using two competing perceptual constraints weighted with two parameters, respectively λ and α. The first one aims at increasing auditory distances between vowel spectra (dispersion), the second one aims at increasing the perceptual salience of each spectrum through formant proximities (focalisation). We also introduced new variants based on research in physics - namely, phase space (λ,α) and polymorphism of a given phase, or superstructures in phonological organisations (Vallée et al., 1999) which allow us to generate 85.6% of 342 UPSID systems from 3- to 7-vowel qualities. No similar theory for consonants seems to exist yet. Therefore we present in detail a typology of consonants, and then suggest ways to explain plosive vs. fricative and voiceless vs. voiced consonants predominances by i) comparing them with language acquisition data at the babbling stage and looking at the capacity to acquire relatively different linguistic systems in relation with the main degrees of freedom of the articulators; ii) showing that the places “preferred” for each manner are at least partly conditioned by the morphological constraints that facilitate or complicate, make possible or impossible the needed articulatory gestures, e.g. the complexity of the articulatory control for voicing and the aerodynamics of fricatives. A rather strict coordination between the glottis and the oral constriction is needed to produce acceptable voiced fricatives (Mawass et al., 2000). We determine that the region where the combinations of Ag (glottal area) and Ac (constriction area) values results in a balance between the voice and noise components is indeed very narrow. We thus demonstrate that some of the main tendencies in the phonological vowel and consonant structures of the world’s languages can be explained partly by sensorimotor constraints, and argue that actually phonology can take part in a theory of Perception-for-Action-Control.
This article presents new experimental data on the phonetics of syllabic /l/ and syllabic /n/ in Southern British English and then proposes a new phonological account of their behaviour. Previous analyses (Chomsky and Halle 1968:354, Gimson 1989, Gussmann 1991 and Wells 1995) have proposed that syllabic /l/ and syllabic /n/ should be analysed in a uniform manner. Data presented here, however, shows that syllabic /l/ and syllabic /n/ behave in very different ways, and in light of this, a unitary analysis is not justified. Instead, a proposal is made that syllabic /l/ and syllabic /n/ have different phonological structures, and that these different phonological structures explain their different phonetic behaviours.
This article is organised as follows: First a general background is given to the phenomenon of syllabic consonants both cross linguistically and specifically in Southern British English. In §3 a set of experiments designed to elicit syllabic consonants are described and in §4 the results of these experiments are presented. §5 contains a discussion on data published by earlier authors concerning syllabic consonants in English. In §6 a theoretical phonological framework is set out, and in §7 the results of the experiments are analysed in the light of this framework. In the concluding section, some outstanding issues are addressed and several areas for further research are suggested.
'Correction' is the name of a sentence with contrastive focus' the phonological/phonetic realization of which is a single contrastive pitch accent. These sentences predominantly appear in (fictional) dialogues. The first speaker uses grammatical entities against which the next speaker protests with a sentence nearly identical except that it contains a prosodically marked corrective element. This paper makes contrastive focus visible by means of 'KF' (contrastive focus).
In this paper, we investigate two pairs of structures in German and English: German Weak Pronoun Left Dislocation and English Topicalization, on the one hand, and German and English Hanging Topic Left Dislocation, on the other. We review the prosodic, lexical, syntactic, and discourse evidence that places the former two structures into one class and the latter two into another, taking this evidence to show that dislocates in the former class are syntactically integrated into their 'host' sentences while those in the latter class are not. From there, we show that the most straightforward way to account for this difference in 'integration' is to take the dislocates in the latter structures to be 'orphans', phrases that are syntactically independent of the phrases with which they are associated, providing additional empirical and theoretical support for this analysis — which, we point out, has a number of antecedents in the literature.
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.
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 study examines intraoral pressure for English and German stops in bilabial and alveolar place of articulation. Our subjects are two speakers of American English and three speakers of German. VOICING is the main phonological contrast under evaluation in both word initial and word final position. For initial stops, a few of the pressure characteristics showed differences between English and German, but on the whole the results point to similar production strategies at both places of articulation in the two different languages. Analysis of the pressure trajectory differences between VOICING categories in initial position raises questions about articulatory differences. In the initial closing gesture, time from start of gesture to closure is roughly equivalent for both categories, but the pressure change is significantly smaller on average for VOICED stops. Final stops, however, present a more complicated picture. German final stops are neutralized to a presumed VOICELESS phonological state. English final /p/ is broadly similar to German /p/, but English /t/ often shows no pressure increase at all which is at odds with the conventional account of phonation termination via pressure increase and loss of pressure differential. The results raise the question of whether the German final stops should be considered VOICELESS or some intermediate form, at least as compared to English final stops.
The aim of this paper is to show what role prosodic constituents, especially the foot and the prosodic word play in Polish phonology. The focus is placed on their function in the representation of extrasyllabic consonants in word-initial, word-medial, and word-final positions.
The paper is organized as follows. In the first section, I show that the foot and the prosodic word are well-motivated prosodic constituents in Polish prosody. In the second part, I discuss consonant clusters in Polish focussing on segments that are not parsed into a syllable due to violations of the Sonority Sequencing Generalisation, i.e. extrasyllabic segments. Finally, I analyze possible representations of the extrasyllabic consonants and conclude that both the foot and the prosodic word play a crucial role in terms of licensing. My proposal differs from the ones by Rubach and Booij (1990b) and Rubach (1997) in that I argue that the word-initial sonorants traditionally called extrasyllabic are licenced by the foot and not by the prosodic word (cf. Rubach and Booij (1990b)) or the syllable (cf. Rubach (1997)). For my analysis I adopt the framework of Optimality Theory, cf. McCarthy and Prince (1993), Prince and Smolensky (1993), in which derivational levels are abandoned and only surface representations are evaluated by means of universal constraints.
This paper sketches the morphosyntactic and prosodic properties of questions in Fipa, discussing three varieties: Milanzi, Nkansi and Kwa. The general word order and morphological patterns relevant to question structures are outlined and different types of wh-question constructions are described and tentatively linked to the prosodic features of Fipa questions.
