This paper reports on indications of the nature of the neurolinguistic connection between phonological and lexical components of language, based on a case of phonemic jargon aphasia. Following bihemispheric embolic infarcts, the subject presented with severe fluent aphasia, characterized by fluent strings of phonemes, with virtually no intelligible utterances. Despite nearly total jargonized output, the fundamental phonological processes of speech were largely intact. Specifically she demonstrated: (1) English phonotactics and English stress-timed rhythmic principles, (2) aspirated stops word-initially and glottalized stops word-finally, (3) utterance final declination of pitch, and (4) stressed syllable vowel lengthening. Additionally, regional-specific (Southern American English) phonological processes, including monophthongization, in-gliding, and front vowel backing, were also preserved. Overall, the investigation reveals an example of an intact phonological rule system operating on a grossly disturbed input (lexical representation).
本文报告了基于一例音素性杂乱性失语症病例，语言的语音和词汇成分之间神经语言学联系本质的指征。双侧栓塞性梗死之后，该受试者出现严重的流畅性失语症，其特征为一连串流畅的音素，但几乎没有可理解的话语。尽管产出几乎完全杂乱化，但言语的基本语音过程在很大程度上是完整的。具体而言，她表现出：（1）英语音位规则和英语重音计时节奏原则，（2）词首送气塞音和词尾喉塞音，（3）语句末尾音高下降，以及（4）重读音节元音延长。此外，特定地区（美国南部英语）的语音过程，包括单元音化、滑音和前元音后缩，也得以保留。总体而言，该研究揭示了一个完整的语音规则系统在严重紊乱的输入（词汇表征）上运作的例子。
