A Re-Examination of Stop Identification from Vocalic Transitions: Language-Specific vs. Perceptually Universal Factors (Evidence from Russian)

Previous studies of relative importance of initial (CV) and final (VC) vocalic transitions as cues for identification of deleted stops have revealed the role of various factors that may be roughly classified as linguistic and perceptual ones. The present paper describes two experiments designed to investigate the interplay of these factors, using Russian speech as the source of the test stimuli. Results of the first experiment concerned with identification of voiceless palatalized and nonpalatalized stops in initial, final and intervocalic positions have shown high significance of all linguistic factors and some of their two-factor interactions. Perceptual dominance of VC transition was evident only in the case of palatalized stops. In the second experiment the method of conflicting transitions was applied to investigate perceptual weight of the formant transitions for recognition of intervocalic stops. The major finding of the experiment was that no asymmetry between initial and final transitions was established either for palatalized or nonpalatalized stops. As a rule, linguistic factors outweighed perceptual ones. But in those cases where the former were neutralized the effect of perceptual factors was apparent.
