The central hypothesis of this proposal is that some articulations covary in distinctive features and segments because their acoustic effects are integrated in perception, rather than because those articulations are yoked to each other physiologically. this hypothesis will be tested using two paradigms designed to assess perceptual integration of orthogonal stimulus dimensions: the Garner (1974) paradigm to assess integration among a variety of articulatory covariates in vowel height and [voice] contrasts, and the Nearey (1990) paradigm to assess integration of redundant with distinctive features in labial consonants. This set of experiments focuses on selected contrasts, but investigates each of them comprehensively. If integration can be demonstrated among the acoustic effects of the covarying articulations in these distinctive features and segments, then this aspect of the listener's response to speech signals contributes substantially to reducing the degrees of articulatory freedom allowed the speaker, by selecting those articulatory aggregates that best serve the integrative perceptual mechanisms in the listener. Among other things, this result implies that the acquisition or remediation of articulatory control would be best served by a demanding rather than tolerant listener.

这一建议的中心假设是，一些关节共变 因为它们的声学效果 整合在感知中，而不是因为这些表达是 在生理上相互结合。 这一假设将得到验证 使用两种范式，旨在评估知觉整合的 正交刺激维度：加纳（1974）范式评估 元音高度中各种发音协变量的整合 和[声音]对比，和Nearey（1990）范式来评估 唇辅音中冗余特征与区别特征的整合。 这组实验集中在选定的对比，但调查 每个人都是全面的。 如果可以证明， 在这些独特的声音中， 特征和片段，那么这方面的听众的反应， 语音信号实质上有助于降低 发音自由允许扬声器，通过选择那些发音 最好地服务于整合感知机制的聚合物 倾听 除此之外，这一结果意味着， 或发音控制的补救将最好由一个 要求而不是宽容的倾听者。
