摘要:Allophones are commonly defined as context-specific instantiations of phonemes. For example, the English phoneme /p/ has two allophonic variants in onset: aspirated [ph] syllable-initially (£each) and unaspirated [p] if preceded by /s/ (speech). To account for this variation (among other findings), linguists and psycholinguists have traditionally distinguished between two broad levels of processing: a phonological level where phonemes are represented (i.e., where [p] and [ph] have the same representation: /p/); and a subsequent level where context-specific allophones are represented. However, the claim that phonemes constitute psychologically-real representations has recently been questioned (e.g., Port & Leaiy, 2005).
