通过对构音障碍成年人的知觉学习研究表明，构音障碍言语的适应是由信号的可预测性（说话者属性）和灵活的言语感知系统（听话者属性）驱动的。在这里，我们将适应性调查扩展到青少年人群，并检查成人和青少年听众是否可以学会更好地理解患有构音障碍的青少年说话者。方法按发育阶段分类，成人（n= 42）和青少年（n= 40）听众完成了三阶段知觉学习协议（前测、熟悉和后测）。在前测和后测期间，所有听众都转录了一名患有与脑瘫相关的痉挛性构音障碍的13岁青少年的演讲。在熟悉过程中，一半的成年人和青少年的听众进行结构化熟悉（音频和词汇反馈）的讲话的青少年扬声器构音障碍;和另一半，与讲话的神经典型的青少年扬声器（控制）。然而，听众谁收到构音障碍的熟悉取得了更大的可理解性的改善比那些谁收到控制熟悉。此外，有一个显着的发展阶段，在那里的成年人取得了更大的可理解性改善相对于adolescents.ConclusionsThis研究提供了第一批证据，青少年构音障碍的语音是学习的发现，即使是青少年听众的语音感知系统尚未完全开发。考虑到社会交往在青春期的形成作用，这些提高可理解性的发现提供了重要的临床意义。
PurposeAs evidenced by perceptual learning studies involving adult listeners and speakers with dysarthria, adaptation to dysarthric speech is driven by signal predictability (speaker property) and a flexible speech perception system (listener property). Here, we extend adaptation investigations to adolescent populations and examine whether adult and adolescent listeners can learn to better understand an adolescent speaker with dysarthria.MethodClassified by developmental stage, adult (n= 42) and adolescent (n= 40) listeners completed a three-phase perceptual learning protocol (pretest, familiarization, and posttest). During pretest and posttest, all listeners transcribed speech produced by a 13-year-old adolescent with spastic dysarthria associated with cerebral palsy. During familiarization, half of the adult and adolescent listeners engaged in structured familiarization (audio and lexical feedback) with the speech of the adolescent speaker with dysarthria; and the other half, with the speech of a neurotypical adolescent speaker (control).ResultsIntelligibility scores increased from pretest to posttest for all listeners. However, listeners who received dysarthria familiarization achieved greater intelligibility improvements than those who received control familiarization. Furthermore, there was a significant effect of developmental stage, where the adults achieved greater intelligibility improvements relative to the adolescents.ConclusionsThis study provides the first tranche of evidence that adolescent dysarthric speech is learnable—a finding that holds even for adolescent listeners whose speech perception systems are not yet fully developed. Given the formative role that social interactions play during adolescence, these findings of improved intelligibility afford important clinical implications.
