Method
for the location of burst-onset spectra in the auditoryperceptual space: A study
of place of articulation in voiceless stop consonants
Allard Jongman
and James D. Miller
| A method for distinguishing
burst onsets of voiceless stop consonants in terms of place of articulation
is described. Four speakers produced the voiceless stops in word-initial
position in six vowel contexts. A metric was devised to extract the characteristic
burst-friction components at burst onset. The burst-friction components,
derived from the metric as sensory formants, were then transformed into
log frequency ratios and plotted as points in an auditoryperceptual space
(APS). In the APS, each place of articulation was seen to be associated
with a distinct region, or target zone. The metric was then applied to a
test set of words with voiceless stops preceding ten different vowel contexts
as produced by eight new speakers. The present method of analyzing voiceless
stops in English enabled us to distinguish place of articulation in these
new stimuli with 70% accuracy. |
