On the Structure of the Vowel Nucleus: Experimental Evidence.
Derwing, Bruce R.; And Others
A study of consonant-vowel linkages focused on the nature of the vowel boundaries with onset and codas. Subjects judged the status of various word pairs as possible exemplars of a particular manipulation they had been taught to listen for in model nonsense words. The models were of three distinct tasks: (1) a nucleus substitution task, to replace the vowel sound with /I/; (2) an onset deletion task, to delete everything before the vowel; and (3) a coda substitution task, to replace everything after the vowel sound with /ps/. Analysis of the results was performed from the perspective of classical signal deletion theory. Overall, the results showed a coherent pattern corresponding well to other evidence of real-time phonological organization. Pre-vocalically, all resonants are effectively separable from following vowels, though glides are less so than others. There was also some evidence that pre-vocalic liquids /l/ and /r/ are more vowel-sticky than nasals. Post-vocalically, glides are absolutely vowel-sticky, with listeners finding it almost impossible to separate such glides from vowels. Post-vocalic /r/ was found to be somewhat less tightly bound to the vowel than glides, and /l/ even less so. Only nasals showed unequivocal consonant-stickiness in all tasks. (MSE)
