Abstract :
The perceptual interaction between the consonant and the vowel in fricative+vowel syllables is evaluated. A set of conflicting cue stimuli was used to measure the relative importance of: (a) the influence of the vowel in the previous consonant, and (b) the influence of the fricative in the following vowel. It is concluded that the perceptual interaction between the consonant and the vowel in fricative-vowel syllables can not be explained only by the coarticulatory influence of the consonant or vowel on adjacent segments. The influence of the vowel in the previous fricative is perceptually irrelevant, while the influence of the fricative in the following vowel is more important for the identification of /θ/ and /f/ than for /s/ and /∫/. Actually it is perceptually irrelevant for /∫/ and a little important for /s/. Besides the influence of the fricative in the following vowel is notably dependent on the particular vowel
