The effects of lexical neighbors on stop consonant articulation

Lexical neighbors (words sharing phonological structure with a target word) have been shown to influence the expression of phonetic contrasts for vowels and initial voiceless consonants. Focusing on minimal pair neighbors (e.g., bud - but), this research extends this work by examining the production of voiced as well as voiceless stops in both initial and final syllable/word position. The results show minimal pair neighbors can result both in enhancement and reduction of voicing contrasts (in initial vs final position), and differentially affect voiced vs voiceless consonants. These diverse effects of minimal pair neighbors serve to constrain interactive theories of language processing.
