The Calibrated Error-Driven Ranking Algorithm as a Solution to Oscillation in Antagonistic Constraints: A Necessary Bias for Algorithmic Learning of Kihnu Estonian

This paper investigates the learning of Kihnu Estonian, a minority dialect of Estonian (Balto-Finnic). I propose a set of constraints to account for Kihnu Estonian vowel harmony patterns, and show that they can be used to produce a restrictive grammar for Kihnu Estonian vowel harmony. With this constraint set, I model the acquisition of Kihnu Estonian vowel harmony via the application of the Gradual Learning Algorithm (Boersma and Hayes, 2001). Antagonistic constraints in the set I adopt pose obstacles to successful learning of the vowel patterns attested in the learning data. These obstacles can be circumvented via use of the update rule from the Calibrated Error-Driven Ranking Algorithm (Magri, 2012).This update rule has been argued to be detrimental to learning variation in stochastic OT. However, though it was originally proposed to address the Credit Problem (Dresher, 1999), I show that it is in fact an elegant solution to the learning problems caused by oscillating constraints when modeling acquisition of Kihnu Estonian vowel harmony

Vowel Harmony in the Kihnu Variety of ­Estonian: A Corpus Study

This paper investigates back/front vowel harmony in the Kihnu variety of Estonian. Data from the Estonian Dialect Corpus are analyzed to inform the description of harmony in this dialect, a phenomenon that has been understudied in the literature. Previously reported patterns of categorical harmony (/u/-/y/ and /É/-/æ/ pairs) and transparency (/i/) are confirmed. However, the corpus provides insufficient direct evidence to either support or refute previous descriptions of the /o/-/ø/ pair as non-participatory. Subtleties of a relationship previously described as variable (/e/-/ɤ/ pair) are explored in more depth, with /e/ proposed as a second transparent vowel. Vowel harmony is also explored in Kihnu Estonianâs rich inventory of diphthongs, with intra-syllabic harmony in diphthongs shown to occur at a similar rate to that of inter-syllabic harmony between monophthongs

The Productive Status of Laurentian French Liaison: Variation across Words and Grammar

There are competing views in contemporary phonological theory about how to best represent processes that are pervasive, frequent, and phonologically motivated, yet still lexically sensitive. To what extent can – or should – a process that applies idiosyncratically to different morphemes, words, and even phrases, be represented in a way that allows it to generalize to novel forms? We examine this question by looking at prenominal liaison as it is used in contemporary Laurentian French, spoken in Canada. We present the results of an online production study that compares application of liaison in real vs. nonce nouns, and that considers the effect of nonce nouns’ phonological properties and morphosyntactic context on the process. We interpret our results as evidence that liaison behaviour is driven jointly by lexical representations and an abstract grammar, with properties of the real-word lexicon affecting liaison rates in nonce words. We further show that there is considerable variation in the population in the extent to which speakers produce liaison with real h-aspiré words, but that all speakers nonetheless share an understanding of what types of words are more vs. less likely to undergo liaison
