我们报告了一位只会讲日语的单语女性，她在额下沟及其周围的中央前皮质和运动前皮质（布罗德曼 6 区）梗塞后患上了外国口音综合症 (FAS)。对于我们会说中文和日语的双语合著者来说，她的讲话听起来像是中文或韩文。对单词和句子的定量声学分析表明，音高（基本频率变化）和强度方差似乎降低，全浊声门脉冲减少。这些发现表明，喉部功能障碍是导致 FAS 病例出现异常言语的原因。这可能是由于控制喉功能的运动皮质和前运动皮质的受限区域受损所致。
We report a Japanese-speaking monolingual woman who developed foreign accent syndrome (FAS) following an infarction in the precentral and premotor cortices (Brodmann Area 6) at and around the inferior frontal sulcus. Her speech sounded Chinese or Korean to our bilingual coauthor who speaks Chinese and Japanese. Quantitative acoustic analyses of words and sentences showed that pitch (fundamental frequency variation) and intensity variances appeared lowered and fully voiced glottal pulses were reduced. These findings suggest laryngeal dysfunction that contributes to the unusual speech production in a case of FAS. This may be caused by damage to a restricted area of the motor and premotor cortices that controls laryngeal function.
