Abstract
Previous work on automatic VOT measurement has focused
on positive-valued VOT. However, in many languages
VOT can be either positive or negative (“prevoiced”).
We present a discriminative algorithm that simultaneously
decides whether a stop is prevoiced and
measures its VOT. The algorithm operates on feature
functions designed to locate the burst and voicing onsets
in the positive and negative VOT cases. Tested on
a database of positive- and negative-VOT voiced stops,
the algorithm predicts prevoicing with >90% accuracy,
and gives good agreement between automatic and manual
measurements
