Speakers typically invest less effort in the articulation of sounds and words that are highly predictable from their contexts. Recent research reveals a perceptual corollary to this behaviour, showing that listeners pay less attention to acoustic signal in predictable contexts. The present paper expands on this finding by testing the acceptability and discriminability of sequences of speech with varying levels of predictability. Stimuli are contrast pairs and are either phonotactically attested or else contain an illicit nonhomorganic consonant cluster. Such clusters violate Japanese phonotactics and have been found to elicit perceptual epenthesis in Japanese listeners. The results show that..
