Listeners are exquisitely sensitive to fine-grained acoustic detail within phonetic categories
for sounds and words. Here we show that this sensitivity is optimal given the probabilistic
nature of speech cues. We manipulated the probability distribution of one probabilistic
cue, voice onset time (VOT), which differentiates word initial labial stops in English (e.g.,
``beach" and ``peach"). Participants categorized words from distributions of VOT with wide
