Abstract

PURPOSE:To register a new sound by storing only a character string by providing a sound rule synthesizing part to convert the contents of a storage part, which stores characters, words and sentences, into sound signals and controlling the storage part so as to output the sound corresponding to a result to hear the output sound signal. CONSTITUTION:A sound rule synthesizing part 12 is provided to convert the contents of a storage part 11, which stores the characters, words and sentences, into the sound signals and the contents of an input part 14 to input the result for a user to hear the output sound signal are compared with the contents of the storage part 11. Then, the storage part 11 is controlled so as to output the sound corresponding to the result. Thus, the registration or change of the new sound can be executed only by changing the character strings, which are the contents of the storage part 11, and further only one storage part 11 can be made enough.
