This study investigated the effects of the age of Korean speakers, place of articulation, and phonation types on voice onset time (VOT) of stops. Twenty-five preschoolers, 25 schoolers, and 25 adults who had no history of speech and language impairment produced plosives in /VCV/ words in isolation. A three-way (3?3?3) mixed design was used with the age of speakers (preschoolers, schoolers, adults) as a between-subject factor, the place of articulation (bilabials, alveolars, velars) and phonation types (plain, tense, aspirated consonants) as a within-subject factor. The dependent measure was the VOT values. Results revealed that three main effects were statistically significant. Preschoolers exhibited longer VOTs than adults (p<.05). There were significant differences in VOTs among the place of articulation, showing that speakers had the longest VOTs for velars (velars > alvelars > bilabials) (all p<.05). In addition, the VOTs for aspirated consonants were longer than those for plain and tense consonants, and the differences were significant among three phonation types (aspirated > tense > plain) (all p<.05). The current results suggested that VOTs would be linked to age and development, and schoolers over the age of 11 years had achieved adult-like VOTs. Moreover, the place of articulation and phonation types in Korean stops showed marked factors in normal speakers’ VOT patterns.
