We investigated the influence of lexicality, stress, and vowel amplitude in the perception of vowel allophony in Brazilian Portuguese using an ABX speeded discrimination task. Stress position and lexicality seem to influence the detection of incorrect allophones. We discuss these findings in the context of possible extensions of Articulatory Phonology, a phonological model which can predict lexically specified allophones and gradient word properties.
