PROBLEM TO BE SOLVED: To efficiently create high quality synthesis voice by connecting a plurality of phonemes. SOLUTION: A system comprises: a phoneme storage section for storing a plurality of phoneme data; a synthesis section for creating a voice data which indicates synthesis voice of a text by reading and connecting a phoneme data corresponding to each phoneme, which indicates pronunciation of the input text, from the phoneme storage section; a calculation section for calculating an index value which indicates unnaturalness of the synthesis voice of the text, based on the voice data; a paraphrase storage section for storing a second notation which is paraphrasing of a first notation by relating it to each of the plurality of first notations; a replacing section for replacing the searched notation with the second notation corresponding to the first notation, by searching notation which corresponds to any of the first notation from the text; and a determination section in which the created voice data is output on condition that the calculated index value is smaller than a reference value, and in which the text is input to the synthesis section so that the voice data of the replaced text may be further created, on condition that the index value is the reference value or more.
