Aiming at automatic extraction of F0 control parameters based on a generation model, we proposed an automatic extraction method using utterance information. In the proposed method, constituent phrase information is used for the prediction of initial value of F0 control parameters in the optimal value search. Extraction experiments using short and long sentence sets showed higher extraction accuracy than the extraction without utterance information. The extraction accuracy difference between single sentence samples and major phrases in long sentences showed the need of further information on neighboring phrases for further improvements of extraction accuracy in long sentences.
