The effects of orthography and morphological decomposability in production of -ly complex words
Hye Jeong Yu (Hanshin University)
Abstract
This study aimed to investigate gemination arising from the suffix -ly in Korean
English learners through two experiments. Experiment 1 examined gemination
through the suffix -ly in terms of absolute duration, preceding vowel duration, and
relative duration by Korean English learners and English speakers and compared it
with gemination in simplex words. The results showed no geminate-singleton
contrast in -ly complex words and simplex words for English speakers, but as the
base words contain more orthographic lateral consonants before the suffix -ly,
absolute durations increased. Similarly, Korean English learners at an advanced level
tended to produce longer absolute durations in -ly complex words with more
orthographic lateral consonants in the base word. However, Korean English learners
at both advanced and intermediate levels showed no durational differences associated
with gemination when the preceding vowels were stressed. But they produced longer
absolute durations for double laterals through the suffix -ly than for single laterals.
Simple word had longer absolute durations for double laterals but shorter preceding
vowel durations, resulting in longer relative durations for double laterals. In
Experiment 2, sixty-two Korean English learners rated familiarity and semantic
segmentability of -ly complex words. The results showed that familiarity and
segmentability ratings were correlated, and that weak morpheme boundary by lower
segmentability led the laterals across morpheme boundary to undergo phonetic
reduction, resulting in shorter absolute durations. The duration of -ly complex word
seems to be influenced by spelling information, but morphological decomposability
more strongly affects phonetic reduction of absolute durations of double laterals at
morpheme boundary.
