对84名单侧半球损伤的右利手患者（50名失语症患者，12名非失语性左脑损伤患者和22名右脑损伤患者）和53名无脑损伤的对照患者进行了音素识别测试，该测试检查了S [受试者]识别两个音素之间的声学边界的能力，/d/和/t/，以声音起始时间（VOT）表示。音素识别缺陷（PID），参照对照组的性能定义，仅限于失语症患者;在超过70%的人中，沿着VOT连续体的浊音和清音辅音之间的边界区的识别是不可能的或异常的。虽然语言的流畅性-非流畅性维度和理解水平都与PID无关，但一些证据表明，紊乱的音素输出是失语症的一个维度，与PID特别相关。
Right-handed patients (84) 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 [subject] ability to identify the acoustic boundary between 2 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 limited to aphasics; in over 70% 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 was crucially associated with PID, some evidence pointed to disordered phonemic output as 1 dimension of aphasia that was specifically related to it.
