在世界上大多数语言中，词汇声调是传达意义所必需的语音对比。各种听力、言语和语言障碍影响感知或产生词汇音调的能力，从而严重损害个体的交际能力。声调语言使用者的数量正在增加，即使在其他英语国家，但对词汇声调障碍的临床评估和康复重视不够。词汇音调和其他语音之间的相似性和差异性使得对其生理基础的更丰富的科学理解对于更有效地补救言语和语言障碍至关重要。在这里，我们讨论了词汇声调的认知和生物学基础，强调支持其获取，感知和认知表征的神经结构和网络。我们提出了新兴的研究在听力，言语和语言的临床疾病的背景下，这一机构的研究将有助于解决的词汇声调学习。
Lexical tones are a phonetic contrast necessary for conveying meaning in a majority of the world’s languages. Various hearing, speech, and language disorders affect the ability to perceive or produce lexical tones, thereby seriously impairing individuals’ communicative abilities. The number of tone language speakers is increasing, even in otherwise English-speaking nations, yet insufficient emphasis has been placed on clinical assessment and rehabilitation of lexical tone disorders. The similarities and dissimilarities between lexical tones and other speech sounds make a richer scientific understanding of their physiological bases paramount to more effective remediation of speech and language disorders in general. Here we discuss the cognitive and biological bases of lexical tones, emphasizing the neural structures and networks that support their acquisition, perception, and cognitive representation. We present emerging research on lexical tone learning in the context of the clinical disorders of hearing, speech, and language that this body of research will help to address.
