Researchers often use metalinguistic judgments to investigate phonological representations. The representations are assumed to govern speech motor control and thereby shape articulatory and acoustic characteristics of speech. Yet little is known about the relationship between metalinguistic judgments, phonological representations, and motor control. This paper reports on an experiment that directly investigates the relation between metalinguistic judgments and articulatory control, hypothesizing that the two share a common representation. This hypothesis predicts that differences in judgments should be correlated with differences in the acoustic characteristics of responses. An experiment was conducted in which syllable count judgments and productions of words with tense vowel/diphthong nuclei and liquid codas were obtained from native speakers of English. A subset of these words have previously been shown to exhibit ­variation in syllable count judgments. Acoustic analyses of productions showed that rime ­durations and formant trajectories differed between words associated with monosyllabic vs. disyllabic syllable count judgments. These results support the hypothesis that a common representation is utilized by the processes responsible for metaphonological judgments of syllable count and speech motor control.

共享表征是隐喻判断和言语运动控制的基础

研究人员经常使用元语言判断来研究语音表征。假设表示控制语音运动控制，从而塑造语音的发音和声学特性。然而，人们对元语言判断、语音表征和运动控制之间的关系知之甚少。本文报告了一项直接研究元语言判断和发音控制之间关系的实验，假设两者具有共同的表示。这个假设预测判断的差异应该与响应的声学特征的差异相关。进行了一项实验，其中从母语为英语的人那里获得了音节计数判断和带有时态元音/双元音核和液体尾音的单词的产生。这些词的一个子集以前已被证明在音节计数判断中表现出变化。产生的声学分析表明，与单音节与双音节音节计数判断相关的单词之间的韵母持续时间和共振峰轨迹不同。这些结果支持了一个假设，即负责音节计数和语音运动控制的隐喻判断的过程使用了一个共同的表示。产生的声学分析表明，与单音节与双音节音节计数判断相关的单词之间的韵母持续时间和共振峰轨迹不同。这些结果支持了一个假设，即负责音节计数和语音运动控制的隐喻判断的过程使用了一个共同的表示。产生的声学分析表明，与单音节与双音节音节计数判断相关的单词之间的韵母持续时间和共振峰轨迹不同。这些结果支持了一个假设，即负责音节计数和语音运动控制的隐喻判断的过程使用了一个共同的表示。
