Abstract: Speed variation is a kind of speech variation, a speed variation corpus include of fast, slow and normal speech is constructed. The paper implements and improves training and recognition algorithm based on difference subspace methods, proposes multi-path difference subspace method. Theexperimental results show that the system has good recognition performance for variational speed speech.
