Abstract: A Chinese dialect identification system based on a mixed SOM neural network and SVM is proposed in this paper.Hunan dialects have been selected as the research object.SOM is applied to cluster for the MFCC of various dialects，and SVM is used as the final implement of decision and identification.The results show that this system has better real-time property and identification rate than the conventional methods especially at a low signal-to-noise ratio.
