Abstract
To investigate how temporal features of speech sounds are processed,
elechophysiological data (AEP) were registered in a
deviant detection task. Stimuli were presented in an oddball
design, employing a 5-step voice onset time (VOT) continuum
from [ba] to [pa]. Deviant AEPs showed both an enhanced Nland
N2b component compared with standard AEPs. Moreover,
when standards had a longer VOT than deviants, deviant AEPs
showed a substantial reduction ofthe P2 component. This effect
was missing when the same stimuli were presented in a context
of standards having a shorter VOT. It appears that this effect is
due to an earlier onset of the N2b component in the former
condition, indicating that conscious detection of deviant stimuli
is easier under conditions where a short VOT is matched asainst
a template of a long VOT.
