Residual, long-term effects of cortical injuries upon speech production are rarely examined. In this study, we examined the articulation and discrimination abilities in twelve subjects who received focal, cortical injuries in Vietnam during 1968-1971. The subjects were divided into two groups based upon the hemisphere (right or left) of lesion. Data revealed the left-hemisphere injured group produced a greater number of articulation and discrimination errors than the right-hemisphere injured group. Articulation errors occurred more often than discrimination errors in both groups. However, a feature analysis revealed the left-hemisphere injured group made predominantly combination errors and the right-hemisphere injured group made predominantly place errors. Taken overall, the data suggest the left-hemisphere injured group may experience residual difficulties with the encoding of phonological units while the right-hemisphere injured group appears to have residual problems that may be related to the spatial correlates of speech.
皮质损伤对言语产生的残留长期影响很少被研究。在本研究中，我们考察了1968年至1971年期间在越南遭受局灶性皮质损伤的12名受试者的发音和辨别能力。受试者根据损伤的半球（右或左）分为两组。数据显示，左半球损伤组比右半球损伤组产生了更多的发音和辨别错误。两组中发音错误比辨别错误更常出现。然而，特征分析显示，左半球损伤组主要出现组合错误，而右半球损伤组主要出现部位错误。总体而言，数据表明左半球损伤组在语音单位编码方面可能存在残留困难，而右半球损伤组似乎存在与语音空间相关性有关的残留问题。
