Previous work suggests that learning to perceive speech categories in infancy may be influenced by the distributions of acoustic cues that underlie them. However, studies on this topic have focused on distributions of single cues, especially voice onset time (VOT), whereas natural phonetic categories are typically defined according to multiple cues and, moreover, VOT may constitute a special case as nonhuman animals are known to exhibit categorical perception of this cue. In order to explore the role of cue distributions in a more natural context, and to extend this research beyond the domain of VOT, in this study we exposed infants to different distributions of cues to a non-native contrast of place of articulation in fricatives. Results suggest that young infants are indeed able to track multiple acoustic cue distributions at once, and that these distributions shape infants' perception after a brief exposure, possibly by enhancing the perceptual similarities between acoustically similar tokens.
