音节结尾液体的某些属性可以影响后续停止辅音的发音位置。为了证明这种感知上下文效应，[al-da]、[al-ga]、[ar-da]、[ar-ga] 的自然标记的 CV 部分被切除并替换为从 [da]-[ga] 连续体中提取的紧密匹配的合成刺激。然后将所得的混合双音节呈现给听众，并标记液体和塞音。天然 CV 部分对合成 CV 的感知有两种不同的影响。首先，存在流动类别的影响：听众在 [al] 的上下文中比在 [ar] 的上下文中更频繁地感知到“g”。其次，由于 [al] 和 [ar] 的标记在 [da] 或 [ga] 之前产生，因此产生了效果：当在 [g] 之前产生的液体之后停止时，会出现更多的“g”感知。原始话语的频谱图支持了一种假设，即每种感知效果在语音产生中都存在相似之处。这似乎是另一个例子，其中言语感知的发现反映了言语产生过程中协同发音的补偿。
Certain attributes of a syllable-final liquid can influence the perceived place of articulation of a following stop consonant. To demonstrate this perceptual context effect, the CV portions of natural tokens of [al-da], [al-ga], [ar-da], [ar-ga] were excised and replaced with closely matched synthetic stimuli drawn from a [da]-[ga] continuum. The resulting hybrid disyllables were then presented to listeners who labeled both liquids and stops. The natural CV portions had two different effects on perception of the synthetic CVs. First, there was an effect of liquid category: Listeners perceived “g” more often in the context of [al] than in that of [ar]. Second, there was an effect due to tokens of [al] and [ar] having been produced before [da] or [ga]: More “g” percepts occurred when stops followed liquids that had been produced before [g]. A hypothesis that each of these perceptual effects finds a parallel in speech production is supported by spectrograms of the original utterances. Here, it seems, is another instance in which findings in speech perception reflect compensation for coarticulation during speech production.
