PURPOSE:To obtain satisfactory tone quality similar to the vocalization of a person by connecting shrinkably a VCV(vowel-consonant-vowel) phoneme by changing the degree of shrinkage of a parameter corresponding to the kind of label information, and synthesizing voice by using a base filter and an index approximate filter by a Fourier circuit network. CONSTITUTION:The VCV phoneme are connected shrinkably by changing the degree of shrinkage of the parameter corresponding to the kind of the label information, and the voice is synthesized by using the base filter and the index approximate filter by the Fourier circuit network. In other words, a character string is inputted to a rhythm generator 2, and pitch data is generated, and simultaneously, the character string is also inputted a parameter control part 3, and the kind of a VCV parameter and an interpolation operation are decided. A VCV decided at the parameter control part 3 is drawn out from a VCV parameter file 8, and is connected in a parameter interpolator 7 with a method decided at the parameter control part 3, and is stored in a parameter buffer 6. At the interpolator 7, the linear interpolation of a parameter between V and V is performed when the VCVs are connected mutually. In such a way, it is possible to obtain the satisfactory tone quality similar to the vocalization of the person. |
