ABSTRACT:
A speech synthesis apparatus appropriately transforms a voice characteristic of speech. The speech synthesis apparatus includes an element storing unit in which speech elements are stored, and a function storing unit in which transformation functions are stored, an adaptability judging unit which derives a degree of similarity by comparing a speech element stored in the element storing unit with an acoustic characteristic of the speech element used for generating a transformation function stored in the function storing unit. The speech synthesis apparatus also includes a selecting unit and voice characteristic transforming unit which transforms, for each speech element stored in the element storing unit, based on the degree of similarity derived by the adaptability judging unit, a voice characteristic of the speech element by applying one of the transformation functions stored in the function storing unit.
