PROBLEM TO BE SOLVED: To solve the problem that proper voice pattern models for conversa tional voices cannot be provided. SOLUTION: An m-phoneme set extraction part 10 and a model learning part 3 are provided, and the part 10 uses reading voice m-phoneme set models to recognize 3-phoneme sets held in a conversational voice learning data memory 8 and extracts m-phoneme sets having low recognition rates, and the part 3 uses a time series of feature vectors of tokens held in the memory 8 to learn conversational voice m-phoneme set models with respect to only m-phoneme sets extracted by the part 10.
