Eight-four right-handed patients with unilateral hemispheric damage (50 aphasics, 12 non-aphasic left brain-damaged and 22 right brain-damaged patients) and 53 control patients without cerebral lesions were given a test of phoneme identification which examined the S's ability to identify the acoustic boundary between the two phonemes, /d/ and /t/, expressed in terms of voice-onset time (VOT). Phonemic identification defect (PID), defined with reference to the performance of the control group, was found to be virtually limited aphasics; in over 70 per cent of them, the identification of the boundary zone between voiced and voiceless consonants along the VOT continuum was either impossible or abnormal, While neither the fluency - nonfluency dimension of speech nor the level of comprehension seemed to be crucially associated with PID, some evidence pointed to disordered phonemic output as to one dimension of aphasia that is specifically related to it.
84名单侧半球损伤的右利手患者（50名失语症患者、12名非失语症左脑损伤患者和22名右脑损伤患者）以及53名无脑部病变的对照患者接受了一项音素识别测试，该测试考察了受试者识别两个音素/d/和/t/之间声学边界的能力，这两个音素通过语音起始时间（VOT）来表示。根据对照组的表现定义的音素识别缺陷（PID）实际上仅见于失语症患者；其中超过70%的患者无法或异常识别沿VOT连续体的浊辅音和清辅音之间的边界区域。虽然言语的流畅性-非流畅性维度和理解水平似乎都与PID没有关键关联，但一些证据表明，音素输出障碍是失语症中与PID特别相关的一个维度。
