Voice onset times of /d/ and /t/ were measured for 16 adult subjects (age range 21 to 26 years) under conditions of sobriety and intoxication. Subjects consumed beer to reach intoxication levels between 0.075 and 0.100% as measured using a portable breathalyzer test. Analysis indicated consistent variabilities over time for each subject and resistance of VOT variability to alcohol influence.
