Listeners often perceive illusory vowels when presented with consonant sequences that violate phonotactic constraints in their language. Previous research suggests that the phenomenon motivates speech-perception models that incorporate surface phonotactic information and the acoustics of the speech tokens. In this article, inspired by Bayesian models of speech perception, we claim that the listener attempts to identify target phonemic representations during perception. This predicts that the phenomenon of perceptual illusions will be modulated not only by surface phonotactics and the acoustics of the speech tokens, but also by the phonological alternations of a language. We present the results of three experiments (an AX task, an ABX task and an identification task) with native Korean listeners, and native English listeners as a control group, showing that Korean listeners perceive different sets of illusory vowels in different phonological contexts, in accordance with the phonological processes of vowel deletion and palatalisation in the language.

Previous research shows that aspiration and sonorancy can have inconsistent consonantal effects on vowel F0 across languages, and even within the same language in different studies: they are reported to either lower F0, raise F0, or have neutral effects. This paper is interested in such inconsistent consonantal effects on vowel F0 in Cantonese and Mandarin. The results of a series of production experiments show that: (1) consonantal effects on vowel F0 are language-specific; (2) the consonantal effects can be conditioned by lexical tones. The findings also provide insights for puzzles in historical tone change.
