To evaluate articulatory models of perceptual center (P-center) location, listeners performed perceptual adjustments on stimuli which were extracted from a corpus of articulatory data. To avoid streaming effects, the stimuli were not edited to obtain temporal variation; instead, they varied in stress and segmental content. Adjustments were evaluated as to their simultaneity with acoustic and articulatory events. The first experiment yielded various articulatory and acoustic correlates of P-center location; the second yielded different articulatory predictors and no acoustic effective predictors. Multiple correlation analyses showed a variation from P-center locations predicted by the articulatory events that were associated with other predictors. Thus, P-center locations do not correspond to any particular kinematic articulatory event, but rather to a complex of events taken from throughout the stimuli. These results are discussed in terms of their relevance to a model of P-centers as indices of underlying gestural timing.
为了评估感知中心（P中心）位置的发音模型，听众对从发音数据语料库中提取的刺激进行了感知调整。为了避免流效应，未对刺激进行编辑以获得时间变化；相反，它们在重音和音段内容上有所不同。对调整与声学和发音事件的同步性进行了评估。第一个实验得出了P中心位置的各种发音和声学相关因素；第二个实验得出了不同的发音预测因素，没有声学有效预测因素。多重相关分析表明，与其他预测因素相关的发音事件所预测的P中心位置存在差异。因此，P中心位置并不对应于任何特定的运动发音事件，而是对应于从整个刺激中提取的一系列复杂事件。根据这些结果与作为潜在手势时间指标的P中心模型的相关性进行了讨论。
