Kim, Jonny Jungyun and Eunji Kang. 2021. Phonetic variation of Korean stem-final consonant clusters beginning with a liquid. Studies in Phonetics, Phonology and Morphology 27.2, 161-192. This study presents the results from an auditory analysis of younger Korean speakers’ production of three different double consonant clusters, /lk, lm, lp/ in syllable-final position of 16 monosyllabic word stems. When coda simplification occurred conforming to the syllable structure of Korean, /lk/ and /lp/ were mostly realized as [l], the first liquid element (C₁), whereas few [C₂] tokens occurred. In addition, a substantial amount of [C₁C₂] realizations were identified, indicating the possibility of ongoing sound change towards either [C₁] or [C₁C₂]. Importantly, the degree of [C₁C₂] realizations was conditioned by both the type of C₂ and prosodic factors. Clusters were faithfully realized in the order of [lp], [lm], and [lk], suggesting that articulatory effectiveness and sonority serve as licensing conditions. As an effect of prosodic position, [lm] and [lk] clusters tended to be simplified to [l] phrase-initially, which we interpret as a syntagmatic effect. An effect of contrastive focus was also found for [lk], increasing the degree of [C₁C₂] realization. Implications for the relationship between variant choice and prosodic motivation are discussed.
