Differences in perceptual strategies for lexical segmentation of moderate hypokinetic dysarthric speech, apparently related to the conditions of the familiarization procedure, have been previously reported [Borrie et al., Language and Cognitive Processes (2012)]. The current follow-up investigation examined whether this difference was also observed when familiarization stimuli highlighted syllabic strength contrast cues. Forty listeners completed an identical transcription task following familiarization with dysarthric phrases presented under either passive or explicit learning conditions. Lexical boundary error patterns revealed that syllabic strength cues were exploited in both familiarization conditions. Comparisons with data previously reported afford further insight into perceptual learning of dysarthric speech.
先前有研究报道[Borrie 等人，语言与认知过程（2012）]，中度运动障碍性构音障碍语音的词汇切分在感知策略上存在差异，这显然与熟悉过程的条件有关。本后续研究旨在检验当熟悉刺激突出音节强度对比线索时，是否也会观察到这种差异。40 名听众在熟悉了被动或显性学习条件下呈现的构音障碍短语后，完成了一个相同的转录任务。词汇边界错误模式表明，在两种熟悉条件下都利用了音节强度线索。与之前报道的数据进行比较，进一步深入了解了构音障碍语音的感知学习。
