Abstract
A weighted-constraint analysis of laryngeal neutralization in Georgian word-initial consonant clusters. This study examines the phonological and phonetic nature of laryngeal neutralization in Georgian word-initial consonant clusters, proposing a novel generalization based on detailed phonotactic and phonetic considerations. Previous studies have argued that laryngeal neutralization in Georgian occurs primarily in ‘harmonic clusters’ (e.g., Déprez 1988), where the two obstruents obligatorily share laryngeal specifications. However, a systematic re-examination of the phonotactic distribution and phonetic realization of Georgian initial obstruent clusters reveals a more comprehensive pattern: (i) laryngeal contrasts in fricatives are neutralized in all word-initial obstruent clusters, regardless of their phonotactic classification, and (ii) for stops, complete neutralization of laryngeal distinctions occurs specifically in front-to-back clusters (where O1’s place of articulation is anterior to O2), resulting in O1 surfacing as an unmarked voiceless segment. Building upon these refined empirical findings, the current paper develops an integrated phonetic-phonological analysis within a weighted-constraint grammar framework. By employing detailed phonetic realization constraints and articulatory markedness constraints, this analysis explicitly models two distinct yet interacting phonetic mechanisms driving neutralization: the loss of voicing due to the absence of voicing cues, and the elimination of laryngeal contrast due to gestural overlap between adjacent consonants. This approach successfully replaces previous harmonic cluster analyses, which fail to adequately capture the observed distributional generalizations and phonetic details.
