In phonetics, voice-onset time (VOT) is a
feature of the production of stop
consonants. It is defined as the length of
time that passes between the release of a
stop consonant and the onset of voicing,
the vibration of the vocal folds, or,
according to other authors, periodicity.
Some authors allow negative values to
mark voicing that begins during the period
of articulatory closure for the consonant
and continues in the release, for those
unaspirated voiced stops in which there is
no voicing present at the instant of
articulatory closure.
