This paper gives a moraic analysis of gemination and laryngeal alternations associated with consonant gradation in North Saami. Gradation gives rise to a surface three-way length distinction in consonants, which is essential to understanding length in vowels and diphthongs. It is explained by a system of prosodic rules applying to underlying representations containing only a two-way contrast between geminate and singleton consonants, plus a floating mora present in certain suffixes, which results in surface alternations between extra-long and long or between long and short consonants. An enlightening explanation of quantity alternations is available if one exploits the possibility implicit in moraic theory that the relationship between segments and moras can be surface-contrastive, and we show that recourse to trimoraic syllables is unnecessary, despite the surface three-way length difference. These prosodic alternations also result in shifts in the timing of preaspiration and preglottalisation, as well as loss of these laryngeal specifications.

Adequately accounting for patterns of dissimilation has challenged more than one linguistic theory. This paper brings together evidence for certain recurrent patterns of dissimilation in Austronesian and Australian languages. It does not claim to have found a definitive solution to why these patterns occur, but it does provide indications that avoidance of multiple markedness may be causally implicated. Although the emphasis is different, the proposal offered here thus has fundamental similarities with Alderete (1997) in arguing that where it applies to dissimilation the Obligatory Contour Principle is inseparably connected with marked elements. Its primary contributions are to provide further empirical support for this claim that may not be readily accessible to non-specialists, to generalise the claim to a larger class of data, to suggest that the explanation for such patterns may be cognitive rather than phonetic and particularly to draw attention to conditions under which markedness-triggered dissimilation is suppressed.

This paper reports on a phonetic and phonological study of /t/-affrication in spontaneous British English Received Pronunciation. The study is motivated by the uncertainty surrounding plosive affrication in the literature on lenition and fortition. We suggest that a decision as to the status of a given pattern involving affrication in terms of lenition or fortition should be based on thorough phonetic and phonological analysis. We present a phonetic and phonological account of /t/-affrication, which takes into consideration the temporal and spectral characteristics of the sounds involved, as well as their distribution across phonological environments. Crucially, we compare affricated instances of /t/ with aspirated and fricated ones in the same dataset – the former arguably unmarked in this variety, the latter uncontroversially the result of lenition. We argue that the phonetic and phonological characteristics of /t/-affrication presented in this paper are consistent with an account in terms of fortition rather than lenition.

The lexical tone and intonation contrasts in the Limburgish dialect of Maastricht are remarkable in a number of ways. While a falling pitch contour on an IP-medial syllable signals a non-declarative intonation, on an IP-final syllable it signals a declarative intonation. In addition, although there is a binary tone contrast (Accent 1 vs. Accent 2) and four nuclear intonation contours, only three intonation contours exist for nuclear syllables with Accent 2, while in IP-final position only two intonation contours exist for nuclear syllables with Accent 1, so that the full set of four intonation contours is only observable in IP-medial nuclear syllables with Accent 1. The context-dependent function of the pitch fall and the asymmetries are explained by a grammar in which the OCP is enforced absolutely, and the number of tones per syllable is restricted to two, unless the three tones each represent a different morpheme: OCP, Realise.orph≫#TTT.

According to the OT error-driven ranking model of language acquisition, the learner performs a sequence of slight re-rankings triggered by mistakes on the incoming stream of data, until it converges to a ranking that makes no more mistakes. Two classical examples are Tesar & Smolensky's (1998) Error-Driven Constraint Demotion (EDCD) and Boersma's (1998) Gradual Learning Algorithm (GLA). Yet EDCD only performs constraint demotion, and is thus shown to predict a ranking dynamics which is too simple from a modelling perspective. The GLA performs constraint promotion too, but has been shown not to converge. This paper develops a complete theory of convergence of error-driven ranking algorithms that perform both constraint demotion and promotion. In particular, it shows that convergent constraint promotion can be achieved (with an error-bound that compares well to that of EDCD) through a proper calibration of the amount by which constraints are promoted.

Under the weak layering approach to prosodic structure (Itô & Mester 1992), the requirement that output forms be exhaustively parsed into binary feet, even when the input contains an odd-number of syllables, results in the odd-parity input problem, which consists of two sub-problems. The odd heavy problem is a pathological type of quantity-sensitivity where a single odd-numbered heavy syllable in an odd-parity output is parsed as a monosyllabic foot. The even output problem is the systematic conversion of odd-parity inputs to even-parity outputs. The article examines the typology of binary stress patterns predicted by two approaches, symmetrical alignment (McCarthy & Prince 1993) and iterative foot optimisation (Pruitt 2008, 2010), to demonstrate that the odd-parity input problem is pervasive in weak layering accounts. It then demonstrates that the odd-parity input problem can be avoided altogether under the alternative structural assumptions of weak bracketing (Hyde 2002).

This paper reports on a study of Polish stress, the only uncontested example of a bidirectional system with internal lapses (Kager 2001, McCarthy 2003). The results indicate that Polish stress is non-iterative, a finding that seriously calls into question the existence of this particular stress type. An analysis of the acoustic prominence of syllables traditionally associated with different stress levels suggests that Polish simple words exhibit only one (penultimate) prominence. The stress pattern in compounds is less uniform; they can carry one or two (penultimate) stresses, depending on their prosodic structure. I analyse the distribution of stresses in compounds as governed by clash avoidance. Specifically, compound stems are parsed into separate PWds and assigned separate stresses only if the emergent trochees are non-adjacent. Hence, four-syllable compounds like /tsuʤɔ-ˈʑεmʲεts/ ‘foreigner’ have one stress, while compounds like /banaˈnɔvɔ-arbuˈzɔvɨ/ ‘banana-watermelon’ have two. I ascribe this pattern to the undominated ranking of the *FtFt constraint.

The set of neutral vowels in the vowel-harmony pattern found in Modern Korean sound-symbolic words is traditionally considered to consist of two members: [i] and [ɨ]. Some authors have tentatively put forward the hypothesis that [u] and [y] are also neutral. A corpus study on the phonotactics of Korean sound-symbolic vowel harmony provides quantitative support both for the traditional understanding of [i] and [ɨ] as neutral vowels and for the tentative hypothesis that [u] and [y] are also neutral. Additionally, the corpus study reveals that vowels are neutral to different degrees. The vowel [a] is shown to be partially neutral, but unlike the other neutral vowels which are transparent, [a] is partially opaque. The distribution of diphthongs is also studied.

The Dutch lexicon contains very few sequences of a long vowel followed by a consonant cluster whose second member is a non-coronal. We provide experimental evidence that Dutch speakers have implicit knowledge of this gap, which cannot be reduced to the probability of segmental sequences or to word-likeness as measured by neighbourhood density. The experiment also suggests that the ill-formedness of this sequence is mediated by syllable structure: it has a weaker effect on speakers' judgements when the last consonant begins a new syllable. We provide an account in terms of Hayes & Wilson's (2008) maximum entropy model of phonotactics, using constraints that go beyond the complexity permitted by their model of constraint induction.

This paper reexamines the issue of the mora, the foot and the syllable in Tokyo Japanese, and shows that whereas the mora and the foot are indisputably present and active, the evidence for the syllable is inconspicuous and disputable. Building on this observation, I claim that Tokyo Japanese makes no use of the syllable. Instead, two types of mora are distinguished: regular CV moras and weak (deficient) moras. Weak moras include the moraic nasal, the first part of a geminate and the second part of a long vowel, as well as moras containing an onsetless vowel, a devoiced vowel or an epenthetic vowel. I further argue that feet obey a set of structural constraints stipulating that they be properly headed by a regular full mora. With this enriched notion of mora type, the paper argues that neither the syllable nor any other level of the prosodic hierarchy is obligatory in all languages.

During the fixed initial-stress period of Latin (sixth to fifth centuries BC), internal open syllable vowels were totally neutralised, usually raising to /i/ (*per.fa.ki.oː>perficiō ‘I complete’), whereas in closed syllables /a/ was raised to /e/, but the other vowels remained distinct (*per.fak.tos>perfectus ‘completed’). Miller (1972) explains closed syllable resistance by positing internal secondary stress on closed syllables. However, evidence from vowel reduction and syncope suggest that internal syllables never bore stress in early archaic times. A typologically unusual alternative is proposed: contrary to the pattern normally found (Maddieson 1985), vowels had longer duration in closed syllables than in open syllables, as in Turkish and Finnish, thus permitting speakers to attain the targets for non-high vowels in closed syllables. This durational pattern is manifested not only in vowel reduction, but also in the quantitative changes seen in ‘classical’ and ‘inverse’ compensatory lengthenings, the development CVːCV > CVC and ‘superheavy’ degemination (VːCCV > VːCV).

Norwegian retroflexion exhibits some phonetic properties that do not seem to ‘make sense’. In Standard East Norwegian, an alveolar /ɾ/ causes a following alveolar coronal to become postalveolar, and in the Frogner and Arendal dialects of Norwegian, the same postalveolarisation process is triggered by a uvular /ʁ/. Comparative analyses of Norwegian dialects reveal that these properties are the results of historical changes and phonological diffusion across dialects. Theories attempting to analyse Norwegian retroflexion as phonetically ‘natural’ can neither fully account for these properties of Norwegian retroflexion nor capture the typological generalisations found across Norwegian dialects.
