Bold numbers indicate correct response rates. All sibilants were equally well perceived, but within the group of non-sibilants, perception of kV was significantly less accurate. There were no other main effects or interactions. Methods and Procedure Twenty new listeners were recruited. Procedures were identical to those of Experiment 2.

A comparison of Experiments 2 and 3 reveals that fricative perception is better on the basis of fricative-vowel syllables than fricative noise alone. Also, given vocalic information improvement is much greater for the non-sibilant fricatives as compared to the sibilant fricatives. Regression analyses were performed to determine the extent to which the acoustic parameters could account for the perception results. In order to account for the results from Experiment 3 in which listeners heard fricative-initial syllables, all acoustic properties were entered into a stepwise linear analysis. Since Experiment 2 involved the frication noise only, those acoustic properties relating to other portions of the original fricative-vowel syllables were excluded from the analysis.
