在10名正常人、10名非流利性失语症患者和10名流利性失语症患者中评价了延迟听觉反馈（delayed auditory feedback，DAF）的效果。言语产生任务包括重复声音和单词;命名物体;从给定的刺激词产生句子;回答问题;背诵童谣和阅读。两个延迟使用，180和360毫秒。两个独立的法官评级的强度，持续时间和语音质量的变化患者的反应。所有受试者包括所有流利型失语症患者均表现出一定的失语效应。流利的失语症患者比非流利的失语症患者表现出明显更小的重复效应。传导性失语症患者似乎受损最轻。总体上，180 ms的记忆效应大于360 ms。最大的记忆效应发生在回答问题，其次是重复，阅读，童谣，句子生产和命名，在该顺序。重复一个复杂的单词比重复一个简单的声音产生更大的噪音效果。在研究中使用的3项措施上发现了不同的效果。两个独立的监测系统的变化显然会产生干扰效应。一个系统与言语强度的变化有关，似乎不受失语症的影响。另一个负责言语的持续时间和质的变化，并与产生失语症的病理学有关。
The effect of delayed auditory feedback (DAF) was evaluated in 10 normal human controls, 10 non-fluent aphasics and 10 fluent aphasics. Speech production tasks consisted of repeating sound and words; naming objects; producing sentences from given stimulus words; answering questions; reciting nursery rhymes and reading. Two delays were used, 180 and 360 ms. Two independent judges rated patients'' responses for changes in intensity, duration and quality of speech. All subjects including all the fluent aphasics showed some DAF effect. Fluent aphasics showed a significantly smaller DAF effect than non-fluent aphasics. Patients with conduction aphasia appeared to be the least impaired. Overall DAF effect was greater with 180 ms than with 360 ms. The largest DAF effect occurred during answering questions, followed by repeating, reading, nursery rhymes, sentence production and naming, in that order. Repetition of a complex word produced a greater DAF effect than repetition of a simple sound. A differential effect of DAF was found on the 3 measures used in the study. DAF effects apparently result from changes in 2 separate monitoring systems. One system is related to changes in the intensity of speech and does not appear to be affected by aphasia. The other is responsible for duration and qualitative changes in speech and is differentially affected in relation to pathology producing aphasia.
