ABSTRACT
Voice onset time (VOT) was measured for voiced and voiceless velar stop consonants across three vowel contexts (/i, a, u/) in healthy young adult and older subjects. Analysis showed that mean VOT values for both /k/ and /g/ across the three vowel contexts did not differ between the two groups; however, differences in VOT variability (standard deviation) approached significance; the older subjects exhibited increased variability. This apparent increase in variability may be related to the subtle anatomical and physiological changes with age.
