Grammatical features of fluent aphasic speakers have not received as much attention as those exhibited by non-fluent aphasic speakers. In part, this neglect reflects the difficulty of applying consistent analytical procedures to fluent aphasic speech. For the analytical process to be meaningful, the methodology must be robust, replicable and capable of dealing with the voluble and non-specific output which is often typical of these speakers, and yet be sensitive enough to reveal subtle grammatical differences between aphasic and normal speech. In this paper the methodological problems encountered in applying analytical procedures to spontaneous speech data are discussed. Two different procedures for analysing speech data are compared and applied to samples of fluent aphasic and normal speech. Both procedures reveal that (compared with normal speakers), although these aphasic speakers are capable of producing some well-constructed grammatical structures, the distribution of these structures may differ compared with the distribution exhibited by normal speakers. These results suggest that complex aspects of grammatical organisation may be compromised in some fluent aphasic speakers.
流利型失语症患者的语法特征没有像非流利型失语症患者所表现出的语法特征那样受到同等程度的关注。部分而言，这种忽视反映了将一致的分析程序应用于流利型失语症患者言语的困难。为了使分析过程有意义，该方法必须稳健、可重复，并且能够处理这些患者通常典型的冗长且不具体的输出，同时又要足够敏感，以揭示失语症患者与正常言语之间细微的语法差异。本文讨论了将分析程序应用于自发言语数据时遇到的方法学问题。比较了两种不同的言语数据分析程序，并将其应用于流利型失语症患者和正常言语的样本。两种程序均表明，与正常说话者相比，尽管这些失语症患者能够生成一些结构良好的语法结构，但这些结构的分布与正常说话者所表现出的分布可能有所不同。这些结果表明，一些流利型失语症患者的语法组织复杂方面可能受到损害。
