In this study, the tone of the Tibetan dialect in the pinyin language was taken as the research object. The experimental design is based on the Oddball paradigm stimulus sequence stimulated with tone 55. When the deviations stimuli tone 53, 13 and 114 are randomly presented in the sequence, the brain has a significant negative deflection in the ERP induced by the pre-attention phase deviation stimulus compared with the standard stimulation-induced ERP, and a larger mismatch negativity occurred in the left auditory cortex compared to the right, which is consistent with the results of studies on patients with impaired brain. That is to say, the vocabulary and tone processing shows the advantage of the left hemisphere.
