Contextual additive structure models can representcomplicated dependencies between acoustic features and contextlabels using multiple decision trees. However, its computationalcomplexity of the context clustering is too high for fullcontext labels of speech synthesis. To overcome this problem,this paper proposes two approaches; covariance parameter tyingand a likelihood calculation algorithm using matrix inversionlemma. Experimental results show that the proposed methodoutperforms the conventional one in subjective listening tests.","subitem_description_type":"Other"},{"subitem_description":"NICT/ATR, Kyoto, Japan,
