INTEGRATION OF ARTICULATIONS IN SPEECH

这一提议的中心假设是，有些发音是不同的 因为它们的声学效果是 整合在感知中，而不是因为这些表达是 在生理上彼此相连。这一假设将得到检验。 使用两个旨在评估知觉整合的范例 正交刺激维度：加纳(1974)评估范式 不同发音协变量在元音高度上的整合 和[声音]的对比，以及Nearey(1990)的范式来评估 唇辅音中冗余特征与明显特征的整合。 这组实验侧重于选定的对比，但调查 他们中的每一个都是全面的。如果可以在以下方面展示集成 在这些独特的声音中，不同发音的声学效果 特征和细分，然后这方面的听众的反应 语音信号实质上有助于降低 发音自由允许演讲者，通过选择那些发音 最佳地服务于 听众。在其他方面，这一结果意味着收购 或者，对发音控制的补救最好由 苛刻而不是宽容的倾听者。

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.
