This article begins with a review explaining the different purposes of biological taxonomies. Taxonomic units are often dependent on the purpose for which the taxonomy has been constructed. Biological taxonomies provide an analogy that we use to emphasize some of the distinctions among the units of phonetic transcription systems, competence phonologies, and performance phonologies. The units of both phonology and phonetic transcription are considered as possible units of the speech motor system, and some of the difficulties of this assumption are explained. Although phonemic units, like units of phonetic transcription, are useful for many purposes, it is not theoretically necessary to use units derived as part of competence phonologies in systems attempting to explain phonological performance or speech motor performance. In this regard, we challenge the concept of coarticulation, because it is based on assumptions about the role of phonological or phonetic units in speech motor control. We offer an integrated perspective that has implications for research in speech motor control and deficits of the speech motor system. We see speech motor deficits as distinct from, yet possibly interacting with, phonological deficits.
本文开篇是一篇综述，解释了生物分类法的不同目的。分类单位通常取决于构建分类法的目的。生物分类法提供了一个类比，我们用它来强调语音转录系统、能力音系学和表现音系学单位之间的一些区别。音系学和语音转录的单位都被视为言语运动系统的可能单位，并解释了这一假设存在的一些困难。尽管音位单位与语音转录单位一样，在许多方面都很有用，但在试图解释语音表现或言语运动表现的系统中，从理论上来说，并不一定需要使用作为能力音系学一部分而派生出来的单位。在这方面，我们对协同发音的概念提出质疑，因为它基于关于音系或语音单位在言语运动控制中作用的假设。我们提供了一个综合视角，这对言语运动控制研究以及言语运动系统缺陷研究具有启示意义。我们认为言语运动缺陷与音系缺陷不同，但可能相互影响。
