We present results from an experiment which
shows that voice perception is influenced by the
phonetic content of speech. Dutch listeners were
presented with thirteen speakers pronouncing CVC
words with systematically varying segmental
content, and they had to discriminate the speakers’
voices. Results show that certain segments help
listeners discriminate voices more than other
segments do. Voice information can be extracted
from every segmental position of a monosyllabic
word and is processed rapidly. We also show that
although relative discriminability within a closed
set of voices appears to be a stable property of a
voice, it is also influenced by segmental cues – that
is, perceived uniqueness of a voice depends on
what that voice says.
