Abstract
Theories of acoustic invariance propose that stop consonant place identification can be made independently of full consonant-transition information. Consonant and vowel identification is possible within a few milliseconds of stop release, although the distribution of the acoustic energy in the consonant onset spectrum is frequently inconsistent with the distribution for the following vowel. The presence of oral physiologic impairment may be expected to influence whatever consonant-vowel interaction may contribute to syllable perception. The purpose of this study was to examine consonant/vowel identification for two glossectomee speakers and one normal control. For the most impaired speaker, removal of poorly identified vowel information enhanced consonant identification. For the normal speaker and the less impaired speaker, full CVs were well identified. Removal of vowel information diminished correct consonant identification for the glossectomee speaker but for the normal speaker affected only those consonants that had spectra consistent with the following vowel. The data show that when onset spectra are ambiguous, the vowel spectrum weights the onset spectrum to influence identification of the intended consonant place of articulation.
