我们报道了一位患有严重的新医学术语的患者的案例。新词源于普遍的音素替换和频繁保留整体音节结构（例如/revolver/ --> /reveltil/）。单词和非单词阅读以及图片命名同样受到影响。没有发现频率、形象性和语法类别的显着影响。与这种严重的言语障碍形成鲜明对比的是，患者在大声朗读阿拉伯语或拼出的数字时几乎没有出现语音错误，但经常出现单词选择错误（例如 250 -->“四百六十”）。这一观察表明，在语音规划过程中，不同类别的单词由可分离的大脑系统处理到音素选择的水平，比之前假设的更外围的水平。在语音处理过程中，数字词可能会被挑选出来，因为它们构成了特定的语义类别，或者因为它们受益于专门用于产生“自动语音”的特殊大脑机制，或者因为它们是复杂数字产生过程中语音的基本构建块。
We report the case of a patient suffering from a severe neologistic jargon sparing number words. Neologisms resulted from pervasive phoneme substitutions with frequent preservation of the overall syllabic structure (e.g. /revolver/ --> /reveltil/). Word and nonword reading, as well as picture naming, were equally affected. No significant influence of frequency, imageability, and grammatical class was found. In striking contrast with this severe speech impairment, the patient made virtually no phonological errors when reading aloud arabic or spelled-out numerals, but made frequent word selection errors (e.g. 250 --> "four hundred and sixty"). This observation indicates that during speech planning, different categories of words are processed by separable brain systems down to the level of phoneme selection, a more peripheral level than was previously assumed. Number words may be singled out during phonological processing either because they constitute a particular semantic category, or because they benefit from special brain mechanisms devoted to the production of "automatic speech", or because they are the elementary buildings blocks of speech during the production of complex numerals.
