PURPOSE:To obtain a synthesized voice having a desired voice property by using voice data of plural human beings having different voice properties in a voice synthesis device. CONSTITUTION:Synthesis unit data obtained from voices of plural human beings are made to be stored as a data-base 24. When a text and voice wanted to be synthesized into the synthesized voice is inputted, synthesis unit data nearest synthetically in reagard to a phonemic environment, a power, a pitch and a voice property are selected with respect to respective voice synthesis units composing the text. Next, whether the voice property of the speaker of selected synthesis unit data is different from a voice property wanted to be synthesized more than a certain degree or not is checked and in the case the difference is greater than the degree, the voice property of the selected synthesis unit data is converted into the same voice property as the voice property wanted to be synthesized by executing a voice transformation to synthesis unit data. |
