Several psycholinguistic and computational models have examined the perception of illusory vowels, where listeners of a language insert an epenthetic vowel to repair illegal consonant clusters, perceiving VCCV as VCVCV. This study investigated whether these top-down effects can be extended to pitch patterns and induce illusory pitches, where a pitch was perceived on the epenthetic vowel. Tokyo and Kinki Japanese are two dialects in Japan with the same phonotactics, but Tokyo and Kinki Japanese regard LLH (low low high) and LHH as illegal tonal patterns, respectively. We controlled an index representing linguistic exposure to the Tokyo pitch pattern and used an AXB discrimination task to investigate whether the pitch patterns influence the perception. We found that Tokyo dialect listeners with the high index, who have long exposure to the Tokyo pitch pattern, perceived "H” pitch between L and H, whereas the subjects with the low index did not show any preference. These results indicated that pitch patterns were also used in the perception of illusory pitches and were reproduced in a simulation study.
