title: The distribution of perceptual cues in English prevocalic fricatives.
abstract: Two experiments involving deletion of selected segments of syllables were undertaken to investigate the distribution of perceptual cues and the role of right-to-left coarticulation in fricative vowel monosyllables. From 12 original syllables (/f, theta, s, integral/ in combination with /i, u, a/), manipulations were made so that a group of listeners were exposed to transitionless syllables and isolated segments of syllables. Consonant and vowel recognition scores under these conditions showed that right-to-left coarticulation effects are perceptible, but do not contribute to consonant identification. The vocalic effects shown for many monosyllables were consistent with a normalization hypothesis. In agreement with previous literature, spectral cues in frication determine /s, integral/ recognition. These cues also contribute to the identification of many /f/ and /theta/ syllables.
