Vowel Harmony and Subsequentiality
نویسندگان
چکیده
Attested and ‘pathological’ vowel harmony patterns are studied in the context of subclasses of regular functions. The analysis suggests that the computational complexity of phonology can be reduced from regular to weakly deterministic.

Computational Characterizations of Vowel Harmony Patterns and Pathologies
This paper provides a computational analysis of 39 attested vowel harmony patterns in a recent typological analysis (Nevins, 2010), in addition to two unattested harmony patterns which have attracted considerable discussion: ‘majority rules’ (Lombardi, 1999; Baković, 2000) and ‘sour grapes’ (Padgett, 1995). It is shown that these attested patterns, unlike the two unattested ones, are subsequent...
متن کاملVowel Harmony in Korean and Morpheme Correspondence1
The two most controversial aspects of vowel harmony in Korean ideophones are its morphologically restricted nature and the harmonic feature governing these alternations. Not only is the harmony pattern restricted to the ideophone class2, but also the value of the harmonic feature determines the meaning of the ideophone itself. While alternations from one feature to another involve relative lowe...
متن کاملSchwas in Moro Vowel Harmony
Moro is a Kordofanian language spoken in the Nuba Mountains of Sudan. It has a vowel height harmony system that presents an intriguing challenge due to the dual nature of the central schwa vowel. Schwas in some morphemes can trigger vowel harmony, while schwas in other morphemes do not. In addition, schwas can appear with both sets of harmonic vowels within morphemes, raising the issue of wheth...
متن کاملThe Roles of Word Stress and Vowel Harmony in Speech Segmentation
Three experiments investigated the role of word stress and vowel harmony in speech segmentation. Finnish has fixed word stress on the initial syllable, and vowels from a front or back harmony set cannot co-occur within a word. In Experiment 1, we replicated the results of Suomi, McQueen, and Cutler (1997) showing that Finns use a mismatch in vowel harmony as a word boundary cue when the target-...
متن کاملTwo Statistical Approaches to Finding Vowel Harmony
The present study examines two methods for learning and modeling vowel harmony from text corpora. The first uses Expectation Maximization with Hidden Markov Models to find the most probable HMM for a training corpus. The second uses pointwise Mutual Information between distant vowels in a Boltzmann distribution, along with the Minimal Description Length principle to find and model vowel harmony...
