Much of the perceptual information for a stop consonant in an [s]-stop cluster inheres in temporal properties of the acoustic signal local to the period of low energy corresponding to stop closure. However, stop percepts in this context are also influenced by the rate of speech in a precursor phrase to which the cluster is appended. The two experiments in this paper attempt to explore the dissociability of these local and longer-term perceptual influences, and to investigate the interactions between them. The results of the experiments reveal a complex pattern of interactions which suggests that a simple distinction between segmental and suprasegmental temporal information for phonetic contrasts is unrealistic.
在[s]-塞音组合中，关于塞音的许多感知信息都存在于与塞音闭塞相对应的低能量时段局部的声学信号的时间特性中。然而，在这种情况下，塞音的感知也会受到该组合所附属的前一个短语中语速的影响。本文的两个实验试图探究这些局部和长期感知影响的可分离性，并研究它们之间的相互作用。实验结果揭示了一种复杂的相互作用模式，这表明对语音对比的音段和超音段时间信息进行简单区分是不现实的。
