The distinction between the processing of musical information and segmental speech information (i.e., consonants and vowels) has been much explored. In contrast, the relationship between the processing of music and prosodic speech information (e.g., intonation) has been largely ignored. We report an assessment of prosodic perception for an amateur musician, KB, who became amusic following a right-hemisphere stroke. Relative to matched controls, KB's segmental speech perception was preserved. However, KB was unable to discriminate pitch or rhythm patterns in linguistic or musical stimuli. He was also impaired on prosodic perception tasks (e.g., discriminating statements from questions). Results are discussed in terms of common neural mechanisms that may underlie the processing of some aspects of both music and speech prosody.
音乐信息处理与片段语音信息（即辅音和元音）处理之间的区别已得到充分研究。相比之下，音乐处理与韵律语音信息（如语调）之间的关系在很大程度上被忽视了。我们报告了对一位业余音乐家KB的韵律感知评估，他在右脑中风后患上了失音乐症。与匹配的对照组相比，KB的片段语音感知能力得以保留。然而，KB无法辨别语言或音乐刺激中的音高或节奏模式。他在韵律感知任务（如区分陈述句和疑问句）中也存在障碍。我们将根据可能是音乐和语音韵律某些方面处理基础的共同神经机制来讨论这些结果。
