A conceptual framework and mathematical model of the control of articulatory timing are presented, in which feedback systems play a fundamental role. The model applies both to relatively small timescales, such as within syllables, and to relatively large timescales, such as multi-phrase utterances. A crucial distinction is drawn between internal/predictive feedback and external/sensory feedback. It is argued that speakers modulate attention to feedback to speed up and slow down speech. A number of theoretical implications of the framework are discussed, including consequences for the understanding of syllable structure and prosodic phrase organization.
本文提出了一个发音时间控制的概念框架和数学模型，其中反馈系统起着基础性作用。该模型既适用于相对较小的时间尺度，如音节内部，也适用于相对较大的时间尺度，如多短语话语。文中对内部/预测性反馈和外部/感官反馈进行了关键区分。研究认为，说话者会调节对反馈的注意力来加快或减慢语速。本文还讨论了该框架的一些理论意义，包括对音节结构和韵律短语组织理解的影响。
