This study investigates listeners' ability to track individual speakers' habitual speech rate in a dialogue and adjust their perception of durational contrasts. Previous studies that found such adjustments are inconclusive as adjustments can be attributed to exemplars of target structures in the dialogue rather than perceptual calibration of habitual speech rates. In this study, English listeners were presented with a dialogue between a fast and slow speaker, containing no stressed syllable-initial voiceless stops. Listeners then categorized /pi/-/bi/ syllables differing along a voice onset time continuum. Results did not show conclusive evidence that listeners' response differed systematically depending on speakers' habitual speech rate.
本研究调查了听者在对话中跟踪单个说话者惯用语速并调整对时长对比感知的能力。先前发现这种调整的研究结果并不确定，因为这种调整可能归因于对话中目标结构的范例，而不是对惯用语速的感知校准。在这项研究中，英语听众被呈现了一个语速较快和较慢的说话者之间的对话，其中不包含重读音节起始的清塞音。然后，听众对沿嗓音起始时间连续体的 /pi/-/bi/ 音节进行分类。结果并未显示出确凿的证据表明，听者的反应取决于说话者的惯用语速。
