Recognizing reduced forms: Different processing mechanisms for similar reductions

Recognizing phonetically reduced forms is a huge challenge for spoken-word recognition. Phonetic reductions not only occur often, but also come in a variety of forms. The paper investigates how two similar forms of reductions – /t/-reduction and nasal place assimilation in Dutch – can eventually be recognized, focusing on the role of following phonological context. Previous research indicated that listeners take the following phonological context into account when compensating for /t/-reduction and nasal place assimilation. The current paper shows that these context effects arise in early perceptual processes for the perception of assimilated forms, but at a later stage of processing for the perception of /t/-reduced forms. This showsfirst that the recognition of apparently similarly reducedwordsmay rely on different processing mechanisms and, second, that searching for dissociations over tasks is a promising research strategy to investigate how reduced forms are recognized. & 2010 Elsevier Ltd.
