Abstract: This paper discussed the performance and cerebral localization of tone error occurred in patients with aphasia. The definition and characteristics of tone and aphasia were introduced briefly, while focusing on the brain lateralization of the tone. Tone is a language signal, but also has characteristics of melodic acoustic. The dual nature affects the cognitive process of tone languages. Therefore studies at home and abroad about tone showed that the conclusion of advantage of lateralization was inconsistent. In this paper, by summarizing the advantage of lateralization of listening perception with different languages, and generalizing the brain damage localization in aphasia patients with voice disorders, the dominant side of the tone in the brain was discussed. This paper also summarized and discussed the characteristics of voice disorder in aphasia.
