Spectral moments distinguished at least three places of articulation at all window locations, and four places in the majority of cases. Bonferroni post-hoc tests indicated that all four places of articulation were significantly different from each other in terms of normalized amplitude. Bonferroni post-hoc tests indicated that all four places of articulation were significantly different. These CVC tokens were then edited to include only the frication noise portion, using the segmentation criteria described in Jongman et al. Stimuli were presented to listeners in random order at 3-s intervals.
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. Bold numbers indicate correct response rates.
