Rating scales were used to examine the role of burst intensity and burst position in the perception of the stop consonants [d] and [g]. Bursts and formant transitions were combined to form synthetic CV syllables with conflicting (e.g., d‐burst with g‐transitions) and nonconflicting (e.g., d‐burst with d‐transitions) sets of cues. In separate experiments, burst intensity and burst position relative to voicing onset were varied. Subjects were asked to identify and to rate the adequacy of the stimuli with conflicting cues; stimuli with nonconflicting cues were presented in pairs, and subjects rated the adequacy of the consonant of the second syllable relative to that of the first. Within a limited range of burst intensities or positions relative to the following vowel, the nonconflicting burst and transition integrated to form an optimal [d] or [g]. There were substantial individual differences in the way in which subjects responded to a conflicting set of cues. However, results suggest that the conflicting burst is most likely to influence perception when it falls within its optimal range as determined above. [Work supported by NINCDS.]
