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.
