Jaye Padgett's Research


My research is in phonology and phonetics, the study of human speech sound patternings.

 

My main language interest is Russian, but my work is directed at an understanding of language in general. My other language interests include Polish, Irish, and Catalan.

 

My work combines formal analysis, usually within Optimality Theory, with experimental methodologies. I am particularly interested in the role of contrast and perceptual distinctiveness in phonetics and phonology.

 

My work on Russian includes analyses of voicing assimilation and final devoicing (including the interesting behavior of [v]); studies on the historical emergence and realizations of secondary palatalizations as a funciton of contrast and context; phonetic and phonological studies of Russian vowel reduction; the role of contrast in other sound changes such as postvelar fronting and sibilant retroflexion; and exploration of the vowel/glide distinction.

A perceptual study of Polish fricatives, and its relation to historical sound change (with Marzena Zygis, 2007)

This study probes the perception of place distinctions among Polish sibilants using an AX discrimination task, and compares results of thirteen Polish- and ten English-speaking subjects. Besides providing information on the relative discriminability of the sibilants, the perceptual study is designed to investigate the claim that a particular kind of diachronic change which has taken place in Polish and other languages, as well as related facts about sibilant inventories, could be perceptually motivated. The results lend support to this claim and to the general view that a principle of dispersion plays a role in explaining sound change tendencies, and therefore in shaping phonological tendencies, for consonants as well as vowels.

Glides, vowels, and features

(To appear in an issue of Lingua about glides, edited by Ioana Chitoran and Andrew Nevins)

Generative phonologists usually take high vowels like [i,u] and glides like [j,w] to be identical (respectively) in terms of distinctive features. The main argument for this assumption comes from theoretical economy: since syllable theory independently provides us with a means of distinguishing between vowels and glides – as syllable nuclei and margins respectively – there is no need for a featural distinction. This paper shows that in fact vowels must be featurally distinct from glides. Evidence for this comes from phonological processes that distinguish between the segment types, in a way that specifically diagnoses a difference of constriction degree. I further show that the vowel vs. glide distinction is part of a larger hierarchy of segmental distinctions based on constriction degree, as indicated by cross-linguistic generalizations. The implications of these conclusions for cases of high vowel vs. glide contrast are explored.

Contrast, comparison sets, and the perceptual space (with Máire Ní Chiosáin)

(To appear in S. Parker, ed., Phonological argumentation: essays on evidence and motivation, Equinox Publishing.)

In recent years a number of researchers have argued that, in order to adequately explain contrast and its effects, phonology must be systemic: evaluation of a form cannot occur in isolation from unrelated contrasting forms, but must take such forms – what we call a ‘comparison set’ – into account. This presents a formal and empirical challenge for systemic approaches. This paper explores the comparison set within the general approach of dispersion theory, focusing on two matters: the ‘problem of infinity’ and idealisation. A further challenge for the theory, though one shared by many non-systemic approaches too, involves substantiating claims about perceptual distance that underpin the approach. Our discussion of the latter issue focuses on secondary palatalisation contrasts in onset versus coda position, with perceptual data from Irish. Our overall goal in this paper is to clarify the nature of these challenges and to outline our own approach to them.

Adaptive Dispersion Theory and phonological vowel reduction in Russian (with Marija Tabain)

(Published version appears in Phonetica 62, 2005, pp. 14-54.)

Russian exhibits a rich pattern of phonological vowel reduction, by which some vowel contrasts are neutralized in unstressed syllables. Recent work in phonology [Flemming 1995; to appear; cf. Crosswhite 2001; to appear] suggests a mechanism by which phonetic vowel reduction – compression of the overall vowel space due to target undershoot – might lead to patterns like Russian. Presenting acoustic data from 9 speakers of Russian, we use Euclidean distance measures, measures of F1-F0 and F2-F1, and Bayesian classification to provide a basic picture of how the overall vowel space, as well as the distribution of vowels, change as stress is reduced. We are particularly interested in whether contraction of the vowel space in unstressed positions is primarily due to raising, and in whether contrasting pairs of vowels are evenly spaced within and across contexts. Our results provide qualified support for the first hypothesis, but largely do not support the hypothesis of equal spacing, in particular across contexts. Of additional interest, we find that some impressionistically described neutralizations are incomplete.

Russian vowel reduction and Dispersion Theory (2004)

(In Phonological studies 7, Kaitakusha, Tokyo, pp. 81-96.)

Recent work on phonological vowel reduction explains some of its properties by appeal to proposed functional bases (Flemming 1995 [2002], to appear, Crosswhite 2001, to appear, Barnes 2002). This paper explores the feasibility of a Dispersion Theory (DT) account for Russian vowel reduction. No detailed analysis of a case of vowel reduction exists in DT. Also new here is an attempt to base such an analysis on a careful phonetic study, in this case a study of Russian vowel reduction due to Tabain and Padgett (2003). The account succeeds in explaining many aspects of Russian vowel reduction. However, though the phonetic data answers important questions, it also raises difficult new ones.

The evolution of sibilants in Polish and Russian (with Marzena Zygis)

(To appear in the Journal of Slavic Linguistics.)

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 class of consonants, i.e. the sibilants. The analysis is cast within Dispersion Theory, and we provide phonetic and typological data supporting the perceptual distinctiveness claims we make.

Systemic contrast and Catalan rhotics (2003)

Catalan has two contrasting rhotics: a tap and a trill. The two sounds contrast only between vowels, with the distribution otherwise being predictable. This paper argues for an account of them cast within Dispersion Theory (Flemming 1995), calling on constraints requiring that contrast be maintained, and on others requiring that contrasts be perceptually distinct. The appeal to contrast leads to a simpler and more explanatory account of Catalan rhotics compared to previous ones. The analysis also illustrates how it is possible to incorporate more systematic phonetic detail into phonology without predicting the overgeneration of contrast. This is possible because Dispersion Theory proposes constraints on the output that regulate contrast directly. The importance of phonetic detail to uncovering phonological generalizations in other languages is another emerging theme in recent phonology.

Constraint conjunction versus grounded constraint subhierarchies in Optimality Theory (2002)

One of the fundamental original assumptions of Optimality Theory (Prince and Smolensky 1993) is that of strict domination: once a candidate is eliminated from consideration by Eval, it cannot be resurrected, no matter how much better it fares than its competitors on lower-ranked constraints. However, the well known proposal of local constraint conjunction (Smolensky 1993, 1995, 1997) qualifies this basic assumption. The basic idea of constraint conjunction is that two or more violations of some constraint(s) may 'gang up' in a particular way, violating a separate, higher-ranked constraint. Because it explicitly relinquishes the assumption of strict domination, constraint conjunction represents an important departure from the more restrictive original conception of constraint ranking. Further, constraint conjunction faces well known challenges of potential overgeneration. Though there have been several proposals about how to address these challenges, no consensus has emerged. In this paper, I examine several significant uses of constraint conjunction that have been proposed, and suggest that they all can and should be subsumed under a notion independently required, that of the universal constraint subhierarchy (Prince and Smolensky 1993). If this is correct, then constraint conjunction is not required of the theory. In addition, following Prince and Smolensky, I take universal subhierarchies to be derived from linguistically relevant scales. Assuming these are phonetically or psycholinguistically grounded, then we have a promising means by which to address the challenge of overgeneration.

Russian voicing assimilation, final devoicing, and the problem of [v] (2002)

(To appear in Natural Language and Linguistic Theory.)

The behavior of Russian [v] with respect to voicing assimilation and final devoicing presents a well known puzzle. Though [v] undergoes voicing assimilation and final devoicing, it fails to trigger voicing assimilation. The best known accounts for this problem posit that [v] is underlyingly /w/. These accounts presuppose (incorrectly) that all sonorants undergo voicing processes without triggering them. Further, they presuppose a kind of derivational opacity that cannot be recast in terms of any plausible model of derivational levels (as in Lexical Phonology) or output-output faithfulness. I offer a new account of Russian [v] that is entirely surface-oriented. This sound occupies a category intermediate between other obstruents and sonorants, something I call a narrow approximant. This fact, along with uncontroversial phonetic principles, explains why [v] behaves just as it does with respect to voicing processes. The account is supported by phonetic and typological observations, and turns out to be both empirically and explanatorily superior to previous accounts. An important consequence of the argument is that phonology must make reference to more phonetic distinctions than are made available by distinctive feature theory. I discuss how current approaches to contrast make this possible without overgenerating potential contrasts.

The emergence of contrastive palatalization in Russian (2003)

(In Eric Holt, ed., Optimality Theory and language change, pp. 307-335, Kluwer Academic Press, Dordrecht.)

The pervasive palatalization contrast of Russian originated about a thousand years ago, when the 'jer' (high, lax) vowels were dropped in certain weak positions. At that time consonants were allophonically palatalized before front vowels. This allophonic palatalization was retained on consonants before the front jer, after that jer deleted, so that palatalization became phonemic. At the same time, the 'i-backing' allophonic rule (discussed below) was born. Building on the phonetic study below, this paper provides a formal analysis of 'i-backing' as velarization of the preceding consonant before i, and shows how this originated as a consequence of the phonemicization of palatalization. The framework adopted crucially incorporates constraints appealing to the perceptual distinctiveness of contrast.

Contrast and post-velar fronting in Russian (2003)

(In Natural Language and Linguistic Theory 21.1, pp. 39-87)

An in-depth study of another allophonic rule of Russian by which velars can be followed by the vowel i but not its backed counterpart. The rule reflects a sound change that occurred earlier in Russian, and this paper focuses on this sound change. Like other papers just above and below, this is part of a larger program investigating the extent to which Russian allophonic rules, and allophonic rules generally, can be explained by appeal to perceptual distinctiveness of contrast and neutralization avoidance.

Contrast dispersion and Russian palatalization

(In Elizabeth Hume and Keith Johnson, eds., The role of speech perception in phonology, Academic Press, San Diego, CA, pp.187-218, 2001.)

Based on an instrumental phonetic study, argues that a well known rule of 'i-backing' in Russian is instead an instance of velarization of the preceding consonant before the vowel i. In this way Russian behaves as other languages do with a palatalization contrast, in either recasting the palatalized versus plain contrast as plain versus velarized (respectively) before front vowels, or neutralizing the contrast there. Most generally, this paper argues that allophonic processes can be better understood than they typically are, and that an appeal to functional phonetic grounding is crucial.

Markedness, segment realization, and locality in spreading (with Maire Ni Chiosain) (version 2001)

(In Linda Lombardi, ed., Constraints and representations: segmental phonology in Optimality Theory, Cambridge University Press, Cambridge, pp. 118-156, 2001.)

A much reworked version of an older paper by the same name (see below). Recommended for those who struggled through any earlier version. This paper argues that given a theory of phonology with an explicit functional phonetic basis, certain classes of "transparency" to feature spreading disappear. (That is, they are seen as artifacts of traditional formal theories.) The point is demonstrated for consonantal transparency in vowel harmony, focusing on Turkish.

The unabridged feature classes in phonology

(A shorter version appeared in Language 78.1, 2002)

A consolidation of earlier work ('Feature classes' and 'Partial class behavior and nasal place assimilation'). Certain features recurrently pattern together in phonological rules, including place features, laryngeal features, and vowel color features (backness and roundness). This paper argues for a conception of feature class behavior distinct from that offered by Feature Geometry. This version provides fuller and improved analyses of color harmony (in Turkish) and nasal place assimilation, as well as background discussion of previous approaches to feature classes in generative phonology.

Perceptual distance of contrast: vowel height and nasality

(In Rachel Walker, Motoko Katayama, and Daniel Karvonen, eds., Phonology at Santa Cruz 5, Linguistics Research Center, UC Santa Cruz, pp.63-78, 1997.)

In languages that contrast oral and nasalized vowels, the inventory of nasalized vowels is always equal to or smaller than that of oral vowels. In addition, it is most typically vowel height that is neutralized or altered when vowels are nasalized. This paper examines these facts from the perspective of Dispersion Theory, and shows how a natural account depends on direct reference to the perceptual distinctiveness of contrast.

Markedness, segment realization, and locality in spreading (with Maire Ni Chiosain) (version 1997)

(Report no. LRC-97-01, Linguistics Research Center, Department of Linguistics, UC Santa Cruz.)

An older version of the paper above by the same name. As the later paper does, this paper argues that given a theory of phonology with an explicit functional phonetic basis, certain classes of "transparency" to feature spreading disappear. (That is, they are seen as artifacts of traditional formal theories.) The theoretical approach is less well worked out here than in the later paper, but this paper includes discussion of other kinds of harmony, including coronal consonant harmony.

Inherent VPlace (with Maire Ni Chiosain)

(Report no. LRC-93-09, Linguistics Research Center, Department of Linguistics, UC Santa Cruz, 1993.)

Place of articulation features of consonants and vowels sometimes interact with each other, and sometimes seem to be entirely independent of each other. This paper is couched in feature geometry theory, and proposes that, while vowel place features are geometrically independent of consonant places features, many consonants bear redundant vowel place feature specifications. Effects of plain consonants on vowels are due to these redundant vowel place features. This approach to vowel-consonant interaction explains a major asymmetry: while consonants can alter major place features of vowels by assimilation, the reverse generally does not occur. (The major exception is palatalizing mutations, which we discuss.)
