评估了失语症和右脑受损的非失语症患者标记和辨别发声时间(VOT)不同的合成语音连续体的能力。这些能力与失语症类型和语言理解能力之间的关系进行了调查，并探讨了知觉和VOT差异产生之间的关系。如果受试者不能辨别刺激，他就不能可靠地标记它们；具有正常辨别功能的受试者可能无法可靠地标记刺激。这些结果被解释为与两个处理水平有关；一个基于一组属性检测器的功能，另一个利用这些属性进行语言处理。后者的水平似乎在失语症中选择性地受损。对VOT产生的分析表明，前部失语症患者在语音的发音编程方面存在缺陷；后部失语症患者在选择合适的音素方面存在缺陷。VOT的知觉和产生能力可能部分地与语言理解能力脱节。
Aphasic and right brain-damaged non-aphasic patients'' ability to label and discriminate a synthetic speech continuum differing in voice-onset time (VOT) was assessed. These abilities were investigated in relation to type of aphasia and language comprehension facility, and the relation between perception and production of VOT distinctions was explored. If a subject could not discriminate the stimuli, he could not reliably label them; a subject with a normal discrimination function might be unable to label the stimuli reliably. These results were interpreted in relation to 2 levels of processing; one based upon the function of a set of property detectors, the other making use of these properties for linguistic processing. The latter level seems to be selectively impaired in aphasia. Analysis of VOT production indicated that anterior aphasics have a deficit in the articulatory programming of speech sounds; posterior patients have a deficit in selecting the appropriate phoneme. Performance on the perception and production of VOT may be partially dissociated from language comprehension ability.
