本地语言音素以非本地方式结合在一起可能会被误解，以使其符合本地音调学，而英语听众有偏见听到音节初始[tr]而不是非法[TL] ;感知和心理物理学60（1998）941。什么样的语言知识会导致语音感知偏见？比较了两类模型：单位模型将偏差归因于听众在每个群集的不同经验（例如它们的不同频率）和结构模型，这些模型使用抽象的语音概括（例如禁止[Coronal] [Coronal] [Coronal]序列）。听众（每个实验中的n = 16个）判断合成6 x 6个隔音簇的阵列，其中两个辅音都模棱两可。对于每个刺激令牌，分别评估了停止判断对超声判断的对数比值比的影响，以提供独立于刺激的偏见度量。实验1比较了感知偏差与侵犯不同的结构约束但均为零频率的感知偏差[BW]和[DL]。实验2比较了CCV和VCCV环境中的[DL]的偏差，以研究音节化与分段主义的相互作用，并排除实验1的赔偿账目1。这两种实验的结果都有偏爱结构模型（NSF支持） 。 （c）2002 Elsevier Science B.V.保留所有权利。
Native-language phonemes combined in a non-native way can be misperceived so as to conform to native phonotactics, English listeners are biased to hear syllable-initial [tr] rather than the illegal [tl] (Perception and Psychophysics 34 (1983) 338; Perception and Psychophysics 60 (1998) 941). What sort of linguistic knowledge causes phonotactic perceptual bias? Two classes of models were compared: unit models, which attribute bias to the listener's differing experience of each cluster (such as their different frequencies), and structure models, which use abstract phonological generalizations (such as a ban on [coronal][coronal] sequences). Listeners (N = 16 in each experiment) judged synthetic 6 X 6 arrays of stop-sonorant clusters in which both consonants were ambiguous. The effect of the stop judgment on the log odds ratio of the sonorant judgment was assessed separately for each stimulus token to provide a stimulus-independent measure of bias. Experiment 1 compared perceptual bias against the onsets [bw] and [dl], which violate different structural constraints but are both of zero frequency. Experiment 2 compared bias against [dl] in CCV and VCCV contexts, to investigate the interaction of syllabification with segmentism and to rule out a compensation-for-coarticulation account of Experiment 1. Results of both experiments favor the structure models (supported by NSF). (C) 2002 Elsevier Science B.V. All rights reserved.
