The contemporary view is that a disruption in phonological encoding underlies the speech production deficit in conduction aphasia. We therefore expect to observe a commonality in phonological errors regardless of task - speaking, reading, or writing. A case report is presented of an oral reading task performed by a Thai conduction aphasic with evidence of localized damage in the left temporoparietal zone. He was instructed to read aloud selections from elementary school materials printed in Thai script at his own pace. A phonological analysis of substitution errors revealed that syllable-initial consonants were more vulnerable to disruption than vowels or tones. Tonal errors were seen to be a secondary consequence of a substitution error involving the syllable-initial consonant. His impaired performance is interpreted as evidence in support of a sensorimotor interface system that converts phonological representations derived from visual orthographic input into articulatory motor representations for speech output.

泰国传导性失语症的口头阅读揭示的感觉运动接口组件的功能缺陷

当代观点认为，语音编码的中断是传导性失语症中言语产生缺陷的基础。因此，我们希望观察到语音错误的共性，而不管任务如何——说、读或写。一份病例报告介绍了由泰国传导性失语症患者执行的一项口头阅读任务，并有左侧颞顶区局部损伤的证据。他被要求按照自己的节奏大声朗读用泰文印刷的小学教材中的选集。对替换错误的语音分析表明，音节首辅音比元音或声调更容易被打断。声调错误被认为是涉及音节首辅音的替代错误的次要后果。
