| summary | Research shows that speech segmentation arises from mechanisms involving both lexical/sentential knowledge and sublexical cues (e.g., stress, allophony, phonotactics). However, few studies have indicated how these mechanisms operate in a complex, multi-cue environment. Our research delineates (a) the default hierarchy of weights among segmentation mechanisms/cues, (b) how the hierarchy changes as a function of some interpretive conditions (e.g., signal degradation, lack of lexical or contextual information), (c) the extent to which lexical and sentential knowledge modifies our perception of low-level cues for word boundaries. |
