Coarticulatory Effects in Perception

Santiago Fernández, Sergio Feijóo

The perceptual interaction between adjacent CV segments is studied in Fricative-Vowel syllables from a coarticulatory point of view. The results of a perceptual experiment with conflicting-cue stimuli are analyzed under the assumption, supported by the results, of the possible influence of F-to-V carryover coarticulation on the integration process. The DAC scale was used to estimate the degree of F-to-V carryover coarticulation in the original syllables. The magnitude of the coarticulatory effect permitted us to derive a prediction of the perceptual results based on the articulatory compatibility between the fricative and the vowel. The correlation between actual and predicted decrease in perceptual identification caused by the insertion of a conflicting transition was computed. The results show that the coarticulatory processes cannot explain the outcome of the perceptual experiment. Nevertheless, the perceptual role played by the /i/ transition can be effectively explained as a consequence of the F-to-V coarticulation.
