This paper presents a technique for estimating the influences of channel bias on phonological typology. The technique, based on statistical bootstrapping, enables the estimation of historical probability, the probability that a synchronic alternation arises based on two diachronic factors: the number of sound changes required for an alternation to arise and their respective probabilities. I estimate historical probabilities of six attested and unattested alternations targeting the feature [voice], compare historical probabilities of these alternations, perform inferential statistics on the comparison and, to evaluate the performance of the channel bias approach, compare outputs of the diachronic model against the independently observed synchronic typology. The technique also identifies mismatches between the typological predictions of the analytic bias and channel bias approaches. By comparing these mismatches with the observed typology, this paper attempts to quantitatively evaluate the distinct contributions of the two influences on typology in a set of alternations targeting the feature [voice].

An ongoing debate in phonology concerns the treatment of cumulative constraint interactions, or ‘gang effects’, and by extension the question of which phonological frameworks are suitable models of the grammar. This paper uses a series of artificial grammar learning experiments to examine the inferences that learners draw about cumulative constraint violations in phonotactics in the absence of a confounding natural-language lexicon. I find that learners consistently infer linear counting and ganging cumulativity across a range of phonotactic violations.

Various phonotactic models have been proposed for the prediction of wordlikeness judgements, most of which have focused primarily on segments. This article aims to model wordlikeness judgements when tone is incorporated. We first show how the two major determinants of wordlikeness judgements, i.e. phonotactic probability and neighbourhood density, can be measured when tone is involved. To test the role of the two determinants of wordlikeness judgements in a tone language, judgement data were obtained from speakers of Cantonese. Bayesian modelling was then used to model the judgement data, showing that phonotactic probability, but not neighbourhood density, influences wordlikeness judgements. We also show that phonotactic probability affects the tendency to judge items as absolutely perfect or more or less wordlike, while it does not affect judgements that an item is absolutely not wordlike. Implications of these results for phonotactic modelling and processes involved in wordlikeness judgements are discussed.

Dene (Athabaskan) verbs are widely known for their complex morphophonology. The most complex patterns are associated with two conjugation markers, /s/ and /n/, which are associated with a floating H tone to their immediate left. In this paper, we provide an analysis of /θe/ and /ɲe/, the reflexes of the /s/ and /n/ conjugations in Tetsǫ́t’ıné. Whereas previous accounts of these conjugations have relied heavily on morphological conditioning, we show that, once level ordering, autosegmental phonology and metrical phonology are brought to bear on the problem, morphological conditioning is not required. Within the framework of Stratal OT, we propose the Domain Reference Hypothesis, by which phonological constraints may only refer to morphological domains and their edges. In addition, we show that in Tetsǫ́t’ıné there is a correlation between phonological opacity and morphological structure, as predicted by the Stratal OT model.

This paper presents both dictionary evidence and experimental evidence that the quality of a word's final vowel plays a role in assigning main stress in English. Specifically, a final [i] pushes main stress leftwards – three-syllable words ending with [i] have a strong tendency to take antepenultimate stress. This pattern is compared with the Latin Stress Rule for English, according to which words with heavy penultimate syllables should have penultimate stress. Both pressures are shown to be productive in experiments. Two analyses of the final-[i] generalisation are tested, one using the ‘cloned’ constraint Non-finFt[i], and one using the ‘parochial’ constraint Antepenult[i], which directly penalises [i]-final words which do not have antepenultimate stress. Although it is has less typological support, Antepenult[i] is argued for on the grounds that it correctly predicts participants' behaviour on words with both a heavy penult and a final [i], which are extremely rare in the lexicon.

Phonological coalescence, understood as a type of synchronic alternation in which two phonological elements seem to fuse into one, presents a prima facie challenge for versions of Optimality Theory that assume the principle of containment. If all underlying material has to be present in the output form, replacing two input elements with a single output element is not straightforward. I argue that, under the assumptions of Autosegmental Coloured Containment Theory, a distinct operation of coalescence is unnecessary, as all major types of coalescence patterns can be analysed in terms of (i) adding new association lines between some autosegmental nodes, and (ii) the underparsing of other nodes, leading to their phonetic non-realisation. The proposed analysis accurately reflects the heterogeneity of coalescence alternations, which are shown to fall into three different types.
