在一组精心挑选的家族性阅读障碍成年受试者的言语知觉进行了调查。三个合成语音连续的感知进行了研究：/a/-//，其中稳态频谱线索区分元音刺激; /ba/-/da/，其中快速变化的频谱线索是不同的;和/sta/-/sa/，其中的时间线索，沉默持续时间，系统地变化。这三个连续体，不同的性质的声学线索之间的歧视对，被用来评估受试者的能力，使用稳态，动态和时间的线索。阅读障碍和正常的读者参加了一个识别和两个歧视的任务，每个连续。结果表明，阅读障碍的读者需要更大的沉默时间比正常读者将他们的看法从/sa/到/sta/。此外，虽然有阅读障碍的受试者能够标记和区分合成语音连续体，但他们不一定像正常读者那样使用声学线索，他们的整体表现通常不太准确。
Speech perception was investigated in a carefully selected group of adult subjects with familial dyslexia. Perception of three synthetic speech continua was studied: /a/-//, in which steady-state spectral cues distinguished the vowel stimuli; /ba/-/da/, in which rapidly changing spectral cues were varied; and /sta/-/sa/, in which a temporal cue, silence duration, was systematically varied. These three continua, which differed with respect to the nature of the acoustic cues discriminating between pairs, were used to assess subjects’ abilities to use steady state, dynamic, and temporal cues. Dyslexic and normal readers participated in one identification and two discrimination tasks for each continuum. Results suggest that dyslexic readers required greater silence duration than normal readers to shift their perception from /sa/ to /sta/. In addition, although the dyslexic subjects were able to label and discriminate the synthetic speech continua, they did not necessarily use the acoustic cues in the same manner as normal readers, and their overall performance was generally less accurate.
