Phonotactic constraints and sub-syllabic structure: A difficult relationship

Abstract

Of late, a controversy has arisen over the internal structure of Korean syllables. While there is general agreement that non-phonotactic criteria argue for left-branching, Lee & Goldrick's (2008) left-branching phonotactic analysis is contradicted by Berg & Koops's (2010) claim as to a phonotactically symmetrical syllable structure. A comparison of the methodologies of the two studies, a revisit of the previous data and a new analysis cement the conclusion that there is neither a left-branching nor a right-branching phonotactic effect in Korean syllables. An investigation of the phonotactic structure of Finnish CVC syllables, which exhibit a psycholinguistic left-branching bias much like Korean, reveals that word-initial syllables possess a largely symmetrical organization whereas word-final syllables tend to show a right-branching slant. This curious set of results is consistent with the following three hypotheses: (i) The phonotactic criterion has an inherent VC bias. (ii) Symmetrical syllable structures represent a compromise between left- and right-branching effects. (iii) The strength of phonotactic constraints increases from earlier to later portions of words. The bottom line of this analysis is that, contra all previous claims, phonotactic constraints cannot be used as an argument for sub-syllabic constituency. We discuss the proposal that the basis of the left-branching bias in Korean syllables is instead to be found in the high degree of coarticulation between the onset consonant and the following vowel.
