Two factors have been proposed as the main determinants of phonological typology: channel bias, phonetically systematic errors in transmission, and analytic bias, cognitive predispositions making learners more receptive to some patterns than others. Much of typology can be explained equally well by either factor, making them hard to distinguish empirically.(More)
In an experimental task with novel words, we find that some lexical statistical regularities of Turkish phonotactics are productively extended in nonce words, while others are not. In particular, while laryngeal alternation rates in the lexicon can be predicted by the place of articulation of the stemfinal stop, by word-length, and by the preceding vowel(More)
Harmonic Grammar (HG) is a model of linguistic constraint interaction in which well-formedness is calculated as the sum of weighted constraint violations. We show how linear programming algorithms can be used to determine whether there is a weighting for a set of constraints that fits a set of linguistic data. The associated software package OT-Help(More)
In the experiments reported here, listeners categorized and discriminated speech and non-speech analogue stimuli in which the durations of a vowel and a following consonant or their analogues were varied orthogonally. The listeners' native languages differed in how these durations covary in speakers' productions of such sequences. Because auditorist and(More)
Mutation has typically been viewed in autosegmental frameworks as an instance of ‘object’-type morphology. The central claim of autosegmental phonology (Goldsmith 1976) is that tones, features, and length/weight (that is, moras, in the currently prevailing view) are representational entities in their own right, not simply attributes of segments. Mutation(More)
The Minor Phrase (MiP, aka accentual phrase) is the prosodic constituent that immediately dominates the prosodic word (PWd) in the prosodic structure hierarchy; it may consist of one or more PWd. In Japanese all MiPs are marked by an initial LH rise. This paper examines the scaling of the initial rise in single-word MiPs in Japanese as a function of the(More)
This paper argues that exceptions and other instances of morpheme-specific phonology are best analyzed in Optimality Theory (OT) in terms of lexically indexed markedness and faithfulness constraints. This approach is shown to capture locality restrictions, distinctions between exceptional and truly impossible patterns, distinctions between blocking and(More)
