ABSTRACT:
A speech synthesis apparatus for outputting synthesized speech on the basis of a parameter sequence of a speech waveform includes a parameter generation unit which generates a parameter sequence for speech synthesis on the basis of a character sequence input by a character sequence input unit, and stores the generated parameter sequence in a parameter storage unit. A waveform generation unit is also provided that generates pitch waveforms each for one pitch period on the basis of synthesis parameters and pitch scales included in the parameter sequence, and generates a speech waveform by connecting the generated pitch waveforms in accordance with frame lengths set by a frame length setting unit.
