汉语是一种声调语言。文章从三方面总结了汉语声调加工的脑神经机制研究:1)声调加工是语言性质,还是语音性质;2)声调加工和音段音位加工的异同;3)声调加工与语调加工的异同。首先,汉语声调加工是语言性质,虽然有右脑的参与,但主要表现为左脑偏侧化。其次,汉语声调是一个独立的语音单位,声调加工与音段音位加工的脑神经机制存在一定程度的分离。最后,声调加工与语调加工在脑神经机制上有一定相似性也有很大不同,虽然汉语语调加工主要是语言性质,但存在明显的语音性质。
Chinese is a tonal language. The paper summarizes the research on the mechanism of cranial nerves in Chinese tonal processing from three aspects: 1) whether tonal processing is of a linguistic nature or of a phonological nature; 2) the similarities and differences between tonal processing and phonological processing; 3) the similarities and differences between tonal processing and intonation processing. First of all, Chinese tone processing is a linguistic nature. Although there is involvement of the right brain, it is mainly manifested as lateralization of the left brain. Second, the Chinese tone is an independent unit of speech. There is a certain degree of separation of the cranial neural mechanism of tone processing and phonetic processing. Finally, there is a great difference between the processing of the tone and the processing of the intonation in the neural mechanism of the brain. Although the processing of Chinese intonation is mainly of a linguistic nature, there is a clear phonetic nature.
