Lublinskaja (1996) has reported that dynamic changes in the spectral center-of-gravity (c-o-g) in selected Russian vowels led to changes in vowel identification. Movement of the c-o-g was effected by simultaneous amplitude modulation of two formants placed at the end points of the desired frequency transition. Experiment 1 of the present study explored whether c-o-g effects extend into the processing of consonant-vowel transitions in /da/-/ga/. Three different stimulus sets were synthesized in which the F₃ transition was a formant, a frequency modulated (FM) tone, or a Virtual Frequency (VF) glide. Listeners' identification of /da/ or /ga/ was not affected by changing the means by which spectral changes were made to F₃. Experiment 2 examined whether subjects could identify the type of F₃ transition in /da/ (formant, FM tone, VF glide) after a short training period. Responses did not differ with the transition type, thus, processing of transition information does not depend on the method used to elicit the perception of a frequency change. Experiment 3 was conducted to eliminate a possible confounding of transition cues in the VF stimuli used in Experiments 1 and 2 and to test listener performance in a dichotic listening condition. The results indicate that the dynamic c-o-g effect is evident in identification of English CV's just as it was for Russian vowels. The results lend support to the proposition that neural activity rather than signal energy is summed in the spectral integration process.
