Abstract：In view of the problem that it is difficult to fully capture useful information from a single phonological feature and the waste of data resources caused by fixed length phonological training,this paper proposes to use the method of multi feature fu-sion to preliminarily extract the features of the phonological signal,so that the model can receive comprehensive audio information and effectively solve the problem of under fitting caused by a single feature.The sequence length of different speech features is uni-fied to 1 by using the mean value of sequence features,it not only solves the problem that the indefinite length speech cannot be trained,but also solves the disadvantage of data waste caused by the fixed length phonological training.Dialect classification is car-ried out by using a model structure similar to WaveNet,which further improves the feature extraction ability of dialect classification.The experimental results show that compared with other methods and models,the classification accuracy of the proposed method is significantly improved under the data used in this paper.
