摘要： There is provided a waveform processing device for changing power of each pitch waveform of a segment in order to acquire a natural synthesis speech. A power calculation means 71 selects pitch waveforms one by one from a group of pitch waveforms corresponding to a segment, and calculates a scalar indicating power of a selected pitch waveform. A normalization degree calculation means 72 calculates a degree of normalization which is an index indicating a degree of normalization of a pitch waveform selected by the power calculation means 71, as a function value of an increasing function using the scalar as a variable. A change coefficient calculation means 73 calculates a change coefficient for changing an amplitude value of a pitch waveform selected by the power calculation means 71 based on the scalar and the degree of normalization. An amplitude change means 74 multiplies an amplitude value at each sampling point of a pitch waveform selected by the power calculation means 71 by the change coefficient.

摘要： A method for synthesizing a voice waveform includes compressing voice-element data in a fixed length scheme that uses data from a preceding or succeeding frame. The compressed voice-element data of each voice section is expanded, and the preceding or succeeding frame of the expanded voice-element data is discarded. The remaining voice-element data is synthesized after discarding portions of the expanded voice-element data.

摘要： A method and a system of producing a synthesized voice is provided. A voice sound waveform is provided at a voice sampling frequency based on pronunciation informations. A voice-less sound waveform is produced at a voice-less sampling frequency based on the pronunciation informations. The voice sampling frequency is converted into an output sampling frequency to produce a frequency-converted voice sound waveform with the output sampling frequency, wherein each of the voice sampling frequency and the voice-less sampling frequency is independent from the output sampling frequency. The voice-less sampling frequency is converted into the output sampling frequency to produce a frequency-converted voice-less sound waveform with the output sampling frequency.
