Place of articulation cues for voiced and voiceless plosives and fricatives in syllable-initial position
 

Summary: Place of articulation cues for voiced and voiceless
plosives and fricatives in syllable-initial position

ABSTRACT
In this paper, the acoustic correlates of the labial
and alveolar place of articulation for both plosive
and fricative consonants are investigated, and the re-
sults are analyzed in terms of vowel context, voicing
and manner of articulation. Several measurements,
including formant and noise measurements, are
reported for CVs spoken by two male and two
female talkers. It was found that the spectral
amplitude of frication noise relative to F1 at vowel
onset results in 84% or better correct classi cation
for the fricatives in 3 vowel contexts. For plosives,
a measure which quanti es the amplitude of noise
at high frequencies relative to F1 at vowel onset
(Av-Ahi 8]) resulted in 81 % or better correct
classi cation in the three vowel contexts. Formant
