REGULAR VOICE SYNTHESIZER

摘要

PROBLEM TO BE SOLVED: To provide a regular sound synthesizer capable of implementing the sound synthesizing process via a smaller quantity of calculation with a memory device having a smaller memory capacity than the conventional example. SOLUTION: An acoustic parameter network connected with multiple arcs via nodes for each phoneme based on a sound data base and added with acoustic feature parameters corresponding to the arcs is stored in a memory 21, the connection state of at least three phonemes is expressed based on it, and a connection point distortion table indicating the connection state on each process phoneme is stored in a memory 22. A unit selection section 1 searches the arc series corresponding to each phoneme of the phoneme series in reference to the table based on the inputted phoneme series and reads out and outputs the acoustic feature parameters corresponding to the searched arc series in reference to the network. A parameter time series generation section 2 generates and outputs the time series of the acoustic feather parameters corresponding to the phoneme series, and a sound synthesis section 3 generates the synthesized sound signal corresponding to the phoneme series.
