本文通过一系列实验研究了[s]后中间位置塞音的位置和方式的声学信息模式。在产生和感知中，停顿位置的信息包括偏移处摩擦音的频谱、无声闭合间隔的持续时间、停顿释放爆发的频率与随后的周期性激发共振峰之间的频谱关系以及第一共振峰过渡的频谱和时间特征。类似地，用于停止方式的信息包括无声关闭的持续时间、释放时第一共振峰的频率、第一共振峰转变的幅度以及释放时第二共振峰和第三共振峰的接近度。一个关系被证明存在于感知之间的频谱特性的第一共振峰和持续时间的沉默关闭所需的听到一个停止。这似乎是互惠的这些参数在生产中的不同地方的发音和不同的声乐背景的协变。知觉敏感性的存在，以广泛的生产的声学后果的问题的有效性帐户的言语感知的信号分解成基本的声学线索，然后整合，以产生一个语音识别。有人认为，这是不恰当的归因于心理状态的线索，其唯一的现实是他们的操作角色的物理参数，其操作可以改变信号的phenotic解释。有人建议，语音感知的信息的度量不能是线索，而是，应该寻求一个度量，其中声学和发音动力学是同构的。
A series of experiments is reported that investigated the pattern of acoustic information specifying place and manner of stop consonants in medial position after [s]. In both production and perception, information for stop place includes the spectrum of the fricative at offset, the duration of the silent closure interval, the spectral relationship between the frequency of the stop release burst and the following periodically excited formants, and the spectral and temporal characteristics of the first formant transition. Similarly, the information for stop manner includes the duration of silent closure, the frequency of the first formant at the release, the magnitude of the first formant transition, and the proximity of the second and third formants at release. A relationship was shown to exist in perception between the spectral characteristics of the first formant and the duration of the silent closure required to hear a stop. This appears to reciprocate the covariation of these parameters in production across different places of articulation and different vocalic contexts. The existence of perceptual sensitivity to a wide range of the acoustic consequences of production questions the efficacy of accounts of speech perception in terms of the fractionation of the signal into elemental acoustic cues, which are then integrated to yield a phonetic percept. It is argued that it is inappropriate to ascribe a psychological status to cues whose only reality is their operational role as physical parameters whose manipulation can change the phenotic interpretation of a signal. It is suggested that the metric of the information for phonetic perception cannot be that of the cues; rather, a metric should be sought in which acoustic and articulatory dynamics are isomorphic.
