    Abstract: A speech synthesis system utilizes a periodic waveform decomposition and relocation method which is a coding method in which signals of voiced sound interval among original speech are decomposed into wavelets each of which corresponds to a speech waveform for one period made by each glottal pulse and the wavelets are respectively coded and stored. Then the wavelets nearest to the positions where the wavelets are to be located are selected from stored wavelets and decoded and superposed to each other such that original sound quality can be maintained and duration and pitch frequency of speech segment can be controlled.
