Articulatory Effects on Speech Perception : Adaptation Test of Voicing Feature Detectors.

Abstract

1) In the articulation of voiceless stop consonants, the shift of phonetic boundary occurred even in the case when the identification stimuli and the articulating syllables were from different series, but the repetitive articulation of voiced stop consonants did not show any systematic effects. The cross-series effects of voiceless stop consonants imply that the detectors are selectively sensitive to voiceless feature and they function as a phonetic feature, not as a unit. 2) Repetitive articulation of voiceless stop consonants caused the VOT values to shorten in some subjects. The shortened VOT values in articulation may cause the shift of phonetic boundary, the boundary being displaced toward voiceless category.
